TheGrundig81 no, in most if not all high performance engines, save for some direct injection engines high octane or premium fuel is REQUIRED. No iffs ands or buts

User Name To be fair, there's almost always ifs ands and buts. Manufacturers aren't going to pump out cars that break when you use the wrong octane gas. Some people will use regular regardless (and sometimes, though rare, it may be all that's available). Engineers account for this, so when you use a lower octane fuel the ECU retards the timing so you don't have to worry about knock. Now I'm referring to production cars, and you certainly shouldn't drive it like you stole it on lower octane, but generally it will not cause problems. Kit blocks built for performance will generally be tuned for a very specific fuel, and you'll have to alter that tuning if you decide to cheap out.

Engineering Explained I disagree. I worked for a dealership group for several years while in college. We got performance models of various sorts in all the time with torched pistons, rings, valves, etc. Vast majority of the time we would send the fuel out and it was 87 octane. We would finish up with a nice stamp on the customers 8 month old car work order that said claim denied. The only outlier was Subaru. We would get the occasional turbo model that would blow ringlands.

That's a common misconception about fuel octane levels. High octane (basically 97 onwards) burns more evenly, meaning that you get a more even combustion in each cylinder, making your car accelerate smoother, and runs more efficiently.

+symawd they are doing this for the vast majority of people who do not own a car that requires premium. The point of this video is to show that the cars that just about everyone drives on their daily commute do not need the premium gas and that they are spending extra money that is not required.

+symawd I think you're missing the point of this video Symawd. They're primarily focusing on cars that require regular fuel and how in some places they recommend putting higher octane gas in cars that won't benefit from it. In cars that require higher octane, it needs higher octane. A car that recommends regular won't benefit. That's the main focus of this, mainly people being ignorant about what they should buy.

Eldor Luedtke It's worth mentioning that a lot of "econo-box" cars these days have turbo charged eco options. Those need higher octane fuel to appreciate the fuel efficiency benefits of said lower displacement turbo engines. It often makes me wonder if the fuel economy improvements are worth the increase in fuel price.

Eldor Luedtke What did the 'Corvette' guy say? He said for 'regular driving' regular is fine'...and I assume he upgrades to a higher octane for racing on a track. (as you know, the 'Vette' has different driver-controlled settings for engine performance, so obviously under 'max power' settings, he'd use a 'hotter' fuel)

MrGencyExit64 Eccono-box cars do not, once the turbo goes on that insult goes. I remember a turbo four in a Mustang that beat stock 302 for that year.

Eldor Luedtke Not when the turbo is only there because the engine is so pathetic without it. Going back to Ford as an example, they manufacture a 1L 3-cylinder turbo charged Fiesta. That's about as econo-box as you can get :P

Gerry Nightingale Yes, and performance was lost, my point. Premium gas is not hotter, it resist pre detonation better. Regular gas has as much energy as premium but would explode making that ping or clatter in high compression high performance engines.

ford taurus v8... the sleeper car. its fast but it looks like a soccer mom car. i have to agree with you on this side. some car do required premium gas. not all cars is the same. it depend on the ecu and the compression of the piston i believe. i have experience of witness, friends car that required 91 and put in 87, it would ping specially on a hotter days. ecu, normally would change its timing to reduce its pinging if the knock sensor detect it. thats how people feel its losing performance since the timing either retard or advance to protect the engine from ping. this show didnt even bother poping its gas cap to show what rating of octane its required. cars that required 91 can used the middle 89 one and be fine.

@@DebbieTomkoSUNSHINE this couldn't be any more wrong, have fun with a blown motor.

Even in premium recommended cars, lower octane gas will have the engine pull timing, and fuel economy and performance will drop.

Exactly my Lexus recommends 91 octane or higher but you can use regular if absolutely needed but not recommended. I’ve ran my car on regular and it ran horrible. It’s not good for your knock sensors to run regular if your car recommends premium as the pistons won’t burn all of the fuel that is being injected!!

I don’t know why I’m watching this video. I drive a diesel full size truck.

Higher octane is made for higher compression engines. These engines also knock sensors to compensate for poorer gas. You don't need premium gas on most daily drivers. If you put regular gas into a high compression high output engine it will have less performance. Basically high octane self ignites at a high compression. I hope this helps.

Mine says 87 or higher so I’m not really sure if using the premium would give my car a good cleaning

+dregsta its pretty much the same. its because canada uses a different standard to USA, and Europe does in Europe etc (where we use metric as well I might add LOL) We use RON Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane. in canadia they use MON Motor Octane Number (MON), is determined at 900 rpm engine speed instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern pump gasoline will be about 8 to 12 octane lower than the RON, but there is no direct link between RON and MON. Pump gasoline specifications typically require both a minimum RON and a minimum MON in America they now use the AKI index Anti-Knock Index (AKI), and often written on pumps as (R+M)/2). It may also sometimes be called the Posted Octane Number (PON). In the end the fuels remain about the same Vs other countries and their respective numbers. Supreme in Canadia is the same as 98 octane in Europe and 91 in US of A Side note. Canadia is about to shift to the AKI index as well.... Sigh lets all just get along and use Metric system and the RON. world peace achieved!

+jack black Canada isn't "just about to shift to the AKI as well". It has been using AKI (RON+MON/2) for many years. Certainly as long as I have been driving and that is 39 years.

*ethanol

Even then Ethanol causing issues depends on the particular car, the materials used in fuel system components, how often the car is driven/refueled, how the ECU or carburetor is tuned, etc etc etc. Most cars on the road today won't have issues with ethanol unless they sit for months without running, usually you only see problems with ethanol as a fuel in cars made before the 90s, and even then it depends on the conditions the car is put through. As someone that tunes Bosch ECUs and wrenches on a lot of cars both at work and in my free time, Ethanol is oftentimes beneficial if used properly, and in a performance application, it's great for both making a lot of power (by having a significantly higher octane and much faster rate of expansion during combustion, allowing for timing to be advanced significantly, and producing less heat, at the cost of taking on water easily, requiring a richer fuel mixture to burn properly as opposed to gas, and having properties that make starting an engine in really cold weather quite difficult without a fuel tank and fuel filter heater. It definitely did leave a huge mark though when it was first introduced.

not to mention every motorcycle ive rode takes 90+ octane fuel...

He didn't ask why it was made available for sale, he asked why it was being "sold"(marketed) to people who don't need it, people who need something else.

+Pis Uhoff octane rating is not resistance to detonation. Its fuel burn rate.

SW6 horsepower number do increase with higher octane but not by much. High performance Engine use Premium 91 for a better compression ratio.

Street48 - horsepower numbers do increase, but if they wanted to measure that they should have done a wide open throttle test to see the max numbers. Otherwise you're just measuring how much horsepower it takes to spin the dyno drum and all of the losses involved in doing so (tire deformation, friction, etc)...

dre04mach Exactly, full throttle would have shown a increase in HP if there was any.

***** Ignition timing has a lot to do with horsepower. The more you can advance the timing, the more complete the burn - the more efficient/powerful the engine is.

dre04mach If you advance too much then it will lose power.

+Doug Vandegrift exactly, its about the octane rating for knock prevention. At least here in the US there are standards to adhere to for consumer fuels.

+Doug Vandegrift no no no... If you engine is not built for performance than you do not need to put a higher octane fuel in it. Even if it says to put a higher octane in. The more air to fuel ratio (say a turbo / supercharger) than yes you should put in a higher octane because then engine will be under more load and it will cause less wear on the motor (Higher octane = cleaner burn). But if you're engine is naturally aspirated, more than likley you will not need a higher octane. Of course there are some exceptions for some vehicles.

Higher octane =cleaner burn? You can't be serious. I think it's time to mute this post.

***** You've obviously never read up on octanes. Hahahahaha

Justin Dahl I'm just saying you should always put in what your car's manual specifies. I have a Mustang GT and it recommends 88 octane or higher but to not go any lower even in higher altitudes. It also specifies that there's no need to put in higher octane as this will not increase efficiency or performance. Yes I agree most vehicles only need lowest unleaded gas and no plus or premium but the manual will specify as such. Putting in premium every now and again really doesn't add any benefit. In short know your octane number and stick close to it.

Your test is the way to prove which gas is better.

Car in the test?

7% more mileage 20%+ more cost

Exactly. What compression ratio did this engine have?

I noticed a big difference with fuel consumption when I tried both 87 and 89 octane on a new Toyota Corolla I rented recently while exploring different places in BC. With the regular 87 octane gas, my fuel tank went from full to empty really fast unlike with 89 octane which lasted a lot longer.

tong po They said that in the video

tong po yup that guy in spike hair is dem ess, specially mustang they start ticking if cheap gas use

tong po Higher cylinder compression causes the fuel to explode sooner and faster. It can be described as more of a flash than a burn and the power of the explosion can be gone before the power stoke is complete. The higher the pressure the faster it burns. Premium fuel is designed to burn slower, so it'll still be burning all the way through the power stroke. In fact, before knock sensors could control timing it was common to still have unburned fuel left during the exhaust stroke. Normal cars with normally lower compression burn regular fuel just fine since the compression is matched to the octane. The reason your Subaru had problems is because the regular fuel burned up before it got done pushing the piston; multiple explosions at the beginning causing the knock and burning off before pushing the piston all the way causing low power.

tong po I think most turbo vehicles are required or recommended to use premium. The way I think about it is, the mileage increase from the turbo evens out the cost for premium.

tong po wich is true ive checked everywhere asked almost every gear head i know and any mechanicwho knew and they said the same thing for some cars it works beter and for some it dosent

Finally someone else understands!

octane is the percent of isooctane, end of story.

octane rating used to refer to the percentage of eight carbon chain hydrocarbons in fuel, which burn slower than typical 6 chain hydrocarbons. Modern fuels use other additives to slow the burn rate, so octane rating refers to the rate of fuel burn. Slower burn means less detonation in high compression engines. Premium fuel just burns slower. One way to increase octane rating is add ethanol, and some premium fuels do this. if you want truly clean burning fuel, use E85, but you need a FlexFuel motor to do this.

+okleydokley explaine me why i was wrong, u said the same thing except that u did a mistake and said six carbon chains, but gasoline is made of heptane and isooctan

@@pifoeko4580 usually premium diesel fuels resist "gelling". Gelling is where diesel fuel begins to freeze due to extreme cold.

Not just high-compression, but higher boost as well. Higher boost is similar to having a higher-compression engine, however.

@@WSKRBSCT correct 👍 pre-ignition, or "knock" is when the fuel ignites before the spark plug ignites it. This "detonation" is very damaging to internal engine parts and can cause catastrophic engine failure. Higher octane fuels resist this detonation because they have a higher ignitability rate, AKA flash point but when they do ignite they do so with more energy. Guys all this info can be found via a 10-minute Google search. I could assume that the Civic in the video was producing higher emissions due to unburned fuel, AKA hydrocarbons. Simply put, there was so little air and fuel in the combustion chamber, it was hard for the ignition system to completely burn the higher octane fuel. Now take a high-performance vehicle where the air-and-fuel is very densely packed via boost or high compression, suddenly that air-and-fuel mixture is very easy to get ignited under heat and pressure. Now that mixture pre-ignites AKA detonates. Thus the need for a higher octane fuel. Keep in mind as the boost, compression and power goes up, so does the need for higher octane fuel! Infact, some very high performance street engines that guys have modified for performance, (high compression pistons, aftermarket cam, free flowing cylinder heads, hot tunes, advanced ignition timing, big turbo, injectors or large carb etc) need E85 which is equivalent to 103-105. Furthermore, some race engines run on C16 116 race gas! That is simply not needed on your mom's 96 Honda Accord Automatic however, and since most people drive average cars, that's the point they're trying to make most people do not need premium fuel.

What this guy said ^

Good point besides the fact that shell v-power nitro+ doesn't contain any ethanol, thus boosting its energy per volume. 91 octane with no ethanol has ROUGHLY and I say ROUGHLY 4% more energy per volume than 91 octane E10 (10% ethanol blended gasoline). I personnaly use 91 octane from Ultramar here in my town there is a pump where it's specified wich fuel is blended and wich isnt and that specific location pumps 91 octane no ethanol (2ZZGE with 11:1 C/R engine with 91 octane recommended by manufacturer)

91 the best one I drove more miles with 91

You have more to worry about than just the octane number you also need to either have high strength valves and seats to run modern gas in an old car or buy an additive like zinc to lubricate the older valve train components. Why do we have to do this ? the oil companies removed the lead lubricant that was needed for the emissions problems.

True. I have a budget Hyundai and the manual says to use regular octane gas, and only regular octane. Apparently higher octane fuels can damage the engine.

Allen, is this why some cars have engine knocks? I noticed on my Harley, that if I put in regular, under acceleration stress (I am gunning it) I will get knocks and hesitation at times. When I put in premium, I do not get that at all. Now the engine I have is an older 1999 Screaming Eagle, so it is considered higher performance. So is predetonation causing a "misfire" at the wrong time resulting in knocks/pings? So the regular gas is detonating in the cylinder before the pistons go top dead center? (Is that the right term???)

Gerald Burgos you now have a higher compression engine if you did pistons that raised your compression ratio. Your 1999 Harley does not have an ECM that can adjust your engines timing. It is an AIR cooled engine also that doesn’t have the ability to run at a more constant temperature. You get higher octane gas at lower altitude. Thin air at high altitude can use less octane which means less engine or no predetonation. You can run Shell, Exxon, Chevron, Texaco, etc gas and be more assured of the octane ratings. My Harley is modified at 10.0:1 compression ratio. Gas at convenient stores and especially Valero gas causes engine knock which can put a hole in your piston. The single best thing you can do is install an adjustable ignition. My favorite is Daytona Twin Tec model TC88 on my ‘01 FLHR. You can set it up for 10 different run conditions. I travelled from sea level to 10,000 feet of altitude in Colorado and just dialed in a preset curve to eliminate knocking. Another excellent one is from S&S that can detect engine knock and adjust timing. I used one of these but it did not work well. I now feel this was due to the HSR 42 flat side Mikuni card that can rattle. I also have a high lift short duration cam with heavy valve springs that knocks a little bit. The rocker shafts were very noisy on mine until I installed rocker locks. www.amazon.com/ROCKOUT-Rocker-Products-001-inserts/dp/B014O6XOZS. This was after I tried the S&S ignition. The tapping noise is so quiet now. The guy I sold my S&S ignition to has no problems and it works PERFECT on his engine. I also tried the Screaming Eagle ignition but it didn’t give me results I wanted.

The majority of motorcycle engines, as well as any small performance engines, make incredible power for their size and weight. To do this, they need incredibly high compression ratios, so much so that motocross racers pay in excess of $20 per gallon for high octane fuel. Considering this, I would say it is highly likely that you are experiencing pre detonation from low octane fuel.

I agree but in my experience in running low powered cars and high powered cars the premium gas in Europe at least works better no matter what type of car you use it in.

Surprise - the 1.4L Turbo in the Cruze actually DOES see a gas mileage increase when operating in the hot summer months where heat can cause knock to occur, meaning an occasional premium top-up isn't a bad idea.

Works best for turbo engines..

Cruzes (turbo) run better on premium and also has a popular tune that requires it. So yeah, the cruze I used to own is the only vehicle I ever regularly bought premium for.

Unless it has a turbocharger, which some Cruzes do.

So does it work the other way around... if I pay for 87 octane am I also getting premium and regular out the nozzle?

chief tp which ones, do you know?

hhahhahah! that's what i was thinking. and how come that nature loving woman is driving a gasoline powered car, wtf is that?

Commander Erik Hobo pissed/wrote his name on that tree and she be kissing it and shiiieet. . lmao!

nothing crazy, just you typical canadian liberal hippy yogi greenie feminist vegan type

She can kiss my wood anytime and call it baby... 🤷🏾‍♂️

Premium is higher octane and is less likely to explode on compression.( engine knock) detonation... Does it burn slower?, Less chance of it exploding, so in a way YES. run the lowest and cheapest octane you can, and still not have detonation.

Bladed Angel hey it’s the one and only!!!

So right By the way, you make great videos.

Did you also watch the actual expert's testimony who drives a corvette and puts in regular? Last I checked a corvette isn't a regular car and he's using regular gas (even though it says on his gas cap "Premium only" and as such the video probably did need to be longer to explain why he does so and the research and testimony of experts on the affects of regular vs premium gas on vehicles.

Dylan k - it didn't say premium only it said premium recommended. Some (not all) premium only cars will have detonation issues if you use regular(some do not have knock sensors). Premium recommended cars do have knock sensors and will pull timing when run on regular if they start to have detonation (pre ignition) issues.

Not recommended but required. A Highlander recommends 89 but needs 87. We put 87 in that car. A Mercedes Benz requires 91.

+Tuan Nguyen What about a low compression ratio car?

+Alan Fox scientists found out that octane ( 8 carbons chain) has the highest compression pressure before it spontaneously ignite; as the result, car with smaller chamber volume can get the same power as bigger engine if the smaller engine has a higher compression pressure. So if the engine ( normal in high performance car such as infinity, lexus, bmw.....) has high compression ratio, it needs high octane gas to prevent premature ignition. Putting high octan gas in a regular engine , let's say a chevy cruze in this video, will not do anything. However, if you put a lower octane gas in high performance engine will cause pre-mature ignition and causes knocking. do some research about it and you will see.

+Alan Fox i bet you if the guy take his Corvette and test it, he will see the output different.

Thank you for the insight.

I drive an old beat up car so I will save money and buy the cheap gas.

Pure gas is the way to go

You're capacity to understand is ???? So I probably should not take the time to try to explain! !!

The truest comment one here by far. It's just a subsidy paid by all of us for farmers to grow crops that aren't needed.

regula!!!

Eli buuwe yeah my 528i bmw says clear as day on the gas cap and manual "Minimum 91 octane".

George Parkermi

My friend told me to use regular gas and never drink or text and drive.

Back ta mayheeco, speedy gonzales!

HOTSPIT666...TRUST ME, I THINK AS YOU DO YOU ASSWIPE!!!!

So I suppose 'a government department told me' is better? ;)

CountryHouseGent,...No...how about doing a little research and EDUCATING YOURSELF.

She should be driving a prius lmao

No cars.....How about a bicycle? In my country, there's more bikes than people, and many people (including me and my husband) use their bikes to go to work. over 95% of schoolgoing children and even university students use bikes to get to school/uni.

Julie It depends on the country. When I lived in Madrid, absolutely, we would walk or use public transportation for everything. Had a nice car that we would never use for anything besides getting groceries (only once a week). Now I live in Canada and having a car is a MUST. The city is spread over hundreds of kilometers. Though it takes me only 5 minutes to get to my local supermarket by car, it would take 20 minutes by bike, and I wouldn't be able to carry all my groceries for the week. It's actually less energy efficient.

Thanks for your input, Dennis, but I do believe your logic with regard to grocery shopping is flawed. You cán do your groceries if it's only 20 minutes by bike. That simply is better for the environment ánd saves you time in the gym. There are plenty of ways to be able to transport sufficient amounts. That said, Canada is one of those countries lacking sufficient infrastructure for bikes, as well as have an undesirable organisation of resources within cities (convenience stores vs. actual proper shops, focus on car infrastructure, etc.). We do our groceries once a week as well, by bike, and even the other shopping in the city across the river from our village. Most people do that here, though the elderly tend to use e-bikes nowadays. Obesity rates are linked to high car usage and food waste, which both are detrimental for the environment.

I haven't noticed any difference in my performance as a runner - as I have been eating the EXACT same foods - for the past 5 years .... ( why would I expect a change? ) ... but yet - why does it sound silly when I say it - but NOT - when you state. ... ( haven't noticed any difference in performance since ( he has not ) changed any type of fuel he has been using in his car - since he first got it )

@@tsvandyke you’re comparing biology and machine? Um .. every car and human body requires different things. People change their diets and their cars. Especially the human body changes with time so many make adjustments. It’s your subjective opinion what works for you as it is for anyone else. It’s a terrible argument that you’re comparing your damn diet to fuel intake lol

I did the same and noticed similar. I had an older but decent car, I remember experimenting and seeing no difference. Then I got a different car, did regular for years until price kept going up and I was driving more. Someone mentioned premium helps mileage and I started it. Next thing I knew, I was filling up half the time.. my cars mileage isn’t great but that did help. I also feel city traffic vs. highway traffic makes a difference. Some are very passionate over this and from what most mechanics say, it doesn’t do the harm people say it does. I don’t think it’s worth people screaming over what they feel is better for the engine when people who have spent decades in shops stand by that unless you’re driving a nicer model, it won’t harm the car.

How old is your car
