Some people happen to like information about things they otherwise wouldn't have known. Not everything is tailored toward the impatient

I know the people who build these vehicles and write up the manuals know what they're doing but the manual for my truck suggests you can go up to 16000 kms (10000 mi) between oil changes. Maybe I'm a bit old school but theres no way I'm gettting even close to that before I change my oil.

It's nice to know the "Why" of things

The 2020 Toyota corolla suggests 87 (Research Octane Number 91) or higher. So is it 87 or 91? Any why would they say "or higher"? Why?

What are you talking about? There is a lot of good info in here

Not entirely true my Nissan has sticker that says its recommended but the manual says 91-96 octane.

@@jonathanjuillerat9831 then it is true

Not really true. So car companies started to do recommend on cars that should be on higher octane. Like for example turbo cars yes it may say require 87, but we recommend 91 because that does do better to prevent knock which is a issues with turbo cars especially the older it gets. Turbos cars have mire steps to maintain then people know

Now for natural aspirated engines can do just 85 unless it doe say so less carbon build up

Theres quite a few turbos now certified to run on regular. I OWN one. On average per my data logger I loose 8 degrees of timing -2 after TDC on takeoff for regular with ac on vs 12 degrees BTDC on takeoff with premium! So 14 degrees difference in timing.

But do most people have turbo chargers? I see a lot in Houston, but ifk if that's regional or not

@@jessicacole8404 they do now. A lot of manufacturers have moved towards forced induction, low displacement engines. The main thing to look at is the compression ratio. If it’s more than 10:1 I’d definitely run higher octane fuel, if it was my car. Also keep in mind that the ECU/ECM on many newer vehicles will detune your engine if you run lower octane fuel. It doesn’t hurt to run higher octane, but you can do a lot of damage if you run too low of octane fuel.

My VW 1.8 TSI (turbo stratified injection) specifies 87 octane, and they mean it! Turns out the ECU will not advance spark timing even if the knock sensors are dead quiet, it's simply unable to benefit from the higher octane. OTOH my first gen. Insight with a 1 liter 3 cylinder specifies 87 octane too, but it has 10.8:1 compression, an ECU that wants to run lean whenever possible (as a fuel saving measure) and I go wide open throttle up every hill to keep the speed up so I fill it with 93, at least with 44 mpg in mixed driving it doesn't hurt that bad.

@@evancourtney7746 I was going to say, VW had to fake data to meet emissions regulations I’m not surprised lol. If the engine isn’t experiencing knock, there’s no danger. It’s not a good idea in my opinion for them to tell people they don’t “have” to use higher octane fuel. When they bend a rod or pop a hole in a piston, it’s too late lol.

Yeah this video is really overdue lol A lot of cars now are using forced induction which means it needs higher octane to be more efficient This video would have been helpful if it was released 10 years ago

So simple and yet so not followed by the masses. The exact same thing goes for oil changes. Change your oil by what your owner's manual says, not what your dealer or Jiffy Lube say.

Then again, you may want to avoid buying cars that require it if possible.

Exactly. Just read the manual.

Not many people considering it is the high performance vehicles that need higher octane. Who is going to buy a Ford Mustang or Dodge Charger and put cheap gas in it? And with high compression engines you can really feel the cheap gas- its more sluggish. With a normal engine you don't really feel a difference with high octane. And even in some cases can ping the engine occasionally if the fuel is too rich. I use high octane gas in motorcycles because they get better performance and more gas mileage out it. I can feel the difference in octane because motorcycles are almost always high compression engines. Maybe once in a while if I feel cheap I'll do midgrade. They will run on regular but you feel a reduction in performance and kind of sluggish sometimes. Usually the owner manual on a motorcycle will recommend mid grade or better. On some of the sports cars low octane gas is bad for the engine. But in a regular car or truck high octane makes no difference. It isn't a high enough compression engine to use the octane and can even sometimes ping if the fuel is too rich. There are other factors. Like usually when I talk about "premium gas" I don't mean high octane. I mean like BP or Shell. They have better quality gas compared to most other brands. This does make a difference if you compare a low octane BP gas to low octane Chevron. They have better fuel additives and they also test their gas. A lot of these other brands they don't test their gas and you have shady gas station owners that water down their gas with ethanol and stuff- so you get bad gas mileage. Like my 20 year old junker SUV I have high octane fuel doesn't do anything for it, but it gets a lot better gas mileage with BP gas. And also gets better mileage and performance with ethanol free gas. Motorcycle doesn't seem to be much difference with BP or ethanol free, but does perform better with high octane. Though I try to use a name brand like shell or something in most cases.

@@raymondkidwell7135 The high performance vehicles owners will most likely for sure use higher octane fuel yes. But there are a lot of regular cars that recommend and some even require it that I'm referring to like Mitsubishi outlanders v6, GM's 2.0L turbo vehicles like regal, equinox ect..

I have a car that has been sitting for more than 3 years. Besides replacing the fuel, what else should I replace? Motor oil, trans fluid?

@@IntrovertedN00b Regular gasoline, especially with the added ethanol, will go bad after a month or so, and so I would drain all the gas out of the tank, add fresh gas, then run the fuel pump and discard the first few cups of gas, to be sure to get all the old gas out. I just had to do this with a motorcycle which had 2.5 year old gas and just would not run on all four cylinders. The other fluids will be fine. Be a good idea to start with a fresh oil change so as to keep track and change it every 3000 miles (or 5000 with synthetic). Trans fluid can be changed at its regular interval of every 50K miles. Keep in mind that all vehicle fluids need to be replaced at regular intervals, including power steering fluid (at 100K miles) and brake fluid (100K miles).

HA! Mazda has done the high compression engine correctly with their skyactiv G engine at a 13-1 compression ratio running on 87 octane ;)

It's the same price as premium - and significantly less available. Plus there's the corrosion issue as well.

Ethanol doesn't cause corrosion in any modern motor vehicle back to the 90s.

E85 will clean the carbon in your motor and usually clogs stuff up if you always ran regular gas that corods everything e85 does not cause corrosion

completely left out the part of ethanol being less energy dense and lower MPG than gasoline for some reason, too.

Ya you lose like 2mpg compared to gas henry ford was making his cars to run on ethenal to help the farmers but he wasnt able to out due john Rockefeller and gasoline

Because your car can detect if your duel octane is higher then 87. If you had a turbo car that needs 92+ premium then it will pre ignite and damage your engine if you use regular 87. Your jeep most likely is a 4 cylinder so 87 should be its gas.

@@inorite4553 yes. Newer ‘regular’ cars should be able to detect. (Highly dependent on specific vehicles) But not all cars. Usually high performance cars will require 91 octane minimum (at sea level) and the ECU will assume that’s the minimum in the tank any lesser.... well it’s bad news. Better Fuel eco linked to vehicles that run higher than recommended octane (for vehicles requiring regular gas) have some current issues it is experiencing such as carbon build up (which increases cylinder pressure and increases chance of knocking, the knock sensor usually pulls back some ignition timing from the range it is allowed to), to extreme heat environment, (more fuel to cool cylinder) to low quality low octane gas, to towing. In this situation, sometimes running mid grade works fine to improve this temporary or permanent situation. In non extreme duty situations (like daily driving), sometimes changing to a different gas station can yield some better quality 87 octane gas that can restore fuel eco without the need for mid or prem gas.

This is shown in the video in a close shot of a pump (see at 1:20). The US uses AKI, or Anti-Knock Index, which is defined as (RON + MON)/2. RON, Research Octane Number, measures the performance of the fuel at low temperatures and low speeds. MON, Motor Octane Number, measures the performance in high temperatures and high speed. So, let’s say, a fuel which is RON 92 and MON 82 is the same as AKI 87.

I once saw a video that explained how its calculated. Basicly US 85 and EU 95 is the same. Just different measuring style.

Not always. Again, you have to look at your auto manual and see what it says. The 1.5T Civic for instance, does not require "premium". Some forced induction engines have been tuned so that the timings don't cause pre-ignition for 87+ octane fuel.

My car has turbocharger. It does not need premium

@@KennyakaTI You need to tune your car for higher octane

Normally a turbo will need a minimum of 89 Gasoline

@@outremer91 I don't need to tune it. It's fine. The recommended gas is regular and that's what I'll use.

@Romero Bryan ok? But HOW is it cleaner? Lol

People will say whatever they want to support their own perception, no matter how false.

@@thefuzzypickle8277 Generally speaking premium doesn't contain ethanol. Ethanol - which is in virtually all "regular" gas is corrosive, attracts water, breaks down faster, and is harmful to engines that aren't built to deal with it - and will decrease engine life in said engines. Fortunately virtually all modern cars are built to handle small amounts of ethanol mixed in to fuel, so it generally isn't an issue any more (although it will cause the gas to go bad sooner - but that generally isn't an issue for cars that are regularly used) Long story short, cheaper gases are technically worse because of their additives, but are "fine" and won't damage modern cars. If your car is made in the last 20 years, don't worry about it. (never use cheap fuels in small engines like chainsaws, snowmobiles, etc - it will damage your engine, especially if it's allowed to sit unused) And you probably don't want to use regular gas in vintage cars, they weren't built for ethanol and will suffer the negative effects.

^This, surprised more aren't saying this. Premium is recommended for my vehicle, but during a local gas shortage in 2020, I had to briefly run 87 because that's all that was available; car sounded awful & 'drove' like absolutely crap. Running a lower octane would save me somewhere between $41 - $175/year, but my engine hates it; not even worth it IMO.

ANY substance added to gas that helps prevent, or delays pre-ignition with give gasoline a higher octane rating but, they will not cause the fuel to burn hotter or burn out carbon anymore than a lower octane fuel.

But their drama is so entertaining 🤗

My car recommends 32psi. I find 38psi is much better. Car handles much better, rides better, noticable mpg bump up, and the tires don't look flat. On road trips I set to 40psi.

@@carnage50x 👍🏼obviously manual recommendations are an educated guess to handle most climates and conditions. Higher PSI would mean less drag on your tires, hence better MPG. That could also result in less traction depending on how and what surface you drive. As long as you're aware of what you're putting in and why, you can obviously make adjustments that suit your needs.

@@carnage50x Tire inflation recommendations are a bit different because Engineers cannot control the quality of the air you use. Fuels are regulated to ensure uniformity across markets which allows Engineers to design better performing engines and provide more accurate recommendations for fuel use.

When you are supposed to have premium it’s pretty noticable

Spoken by a complete idiot there is absolutely no difference in performance between your regular and premium and new difference in gas mileage either it's all a dog and pony show to get more money I'm a pilot I used 87 octane in my plane there was a hundred available at the airport tried some absolutely no difference in consumption or performance

If you don’t run premium in a corvette that Mofo gonna build up carbon and ping

@@camerongoff1081 I agree with you because it actually happened. Some other guy called me an idiot for saying that but I got rid of him. I don't have time for childish folks.

@@kenneycooper6199 I have an 02 c5 LS1 and I only run 93 but sometimes I’ll mix in 100 octane with it

Fr. Like yes I’m surprised my gti says use 91 or higher but it’s gonna get 91 of higher even if it seems overkill

100%

I had a Ford Svt car that needed premium only. Ran out of gas in middle of nowhere, someone stopped and gave me some regular gas to get to the gas station. Had to change a sensor because it fowled it up and cause the car to run like ass.

Yes that's the only time you should vs using premium...

My WRX says premium required and I'm not gonna risk messing up my turbo.

Can attest to that my truck allows me to put 87 or 89 or 91 I tried all 3 to see what kind of mileage I would get. On 87 I get about 11 mph, during the week I tested it out, with the 87 I had to fill up twice during the week Filled up on Sunday night, then Wednesday after work. With the 89 I got till Thursday night, while With 91 I made it till Friday. I drive to the same site for work and take the same route to work, minimal traffice and yet I was able to see a difference. While I do pay 10 bucks more per fill up I only have to fill once up on 91.

@@shadowspire That is probably due to the fact that premium grade has no ethanol, therefore more BTU's of energy per gallon.

My 2015 Acura idles perfectly on Premium fuel, gets goes 100 km on 7-9 Litres of fuel in the summer, and the top of the engine is clean--- no carbon or sludge because of the extra additives that are NOT present in Regular fuel. I've got over 110,000 km on the factory spark plugs--- they look like they did when I bought the car.

My wife's Volkswagen golf Tsi requires

Volkswagen lies about their gas mileage so take your mileage with a gain of salt

MID GRADE AT THE LEAST

IF IT SAYS REGULAR IS GOOD BUT PREMIUM IS FINE OR RECOMMENDS PREMIUM BUT REGULAR IS FINE...THEN MID GRADE WHEN ITS CHEAPER AND FUEL PRICES ARE LOWER IS PREFERABLE
