I hope you guys like the animations and all the extras that went into this video! It took a while to do (you guys who follow me on Instagram know lol) but I think it is worth showing you examples instead of just taking my word for it! For those asking, here is where I got the fuel injector cleaner/tester: amzn.to/31kHwhk

He literally took all his family car to the gas station for an intro. That's dedication.

Cashier: 911 I got a strange man talking to his car and pumps again.

Hurts to watch this in 2024..

The gas price 4y ago 😭😭😭😭😭

just the fact that this dude went to the gas station 7 times to take a perfect picture he deserves a like

We just gonna ignore the fact he pulled up to this gas station in like 10 different cars without a change in lighting

This video is legit the gold standard of gasoline explanation videos. Thank you for taking your time to make this!

I've never seen or had someone teach/explain to me the difference in gasoline like the way this guy does. It's actually very informative and easy to follow. Thanks a bunch!

0:15 the fact that he took ALL 7 OF HIS FAMILIES CARS to a station for one clip, just goes to show the amount of effort he puts into these videos and i love it

I literally learn 1 or 2 months of automotive and engine school in 16 minutes... this dude is amazing

$2.37 for 87 octane.. those were the days.

Chris, what a great informative video. You covered all the bases, and it really shows how beneficial higher-octane fuels can be.... for vehicles that require or recommend them. Love the way you clarified the benefits for vehicles that 'recommend' higher octane. Perfect example: my 2021 Ford Edge St has a twin turbo v-6 (2.7 ecoboost). The service manual specifies that the engine will run fine with 87 (thanks to the knock sensors), but for optimum performance or under high load (towing a trailer) applications, premium is recommended. I definitely notice a performance benefit. Kudos to the knock sensors. Also, how older vehicles with high mileage can benefit. Knocking and pinging from carbon hot spots can really do some damage over time. For those of us who know, not a good sound to hear! I have found that Chevron Complete fuel system cleaner works awesome for cleaning carbon out of older engines. Also appreciate the breakdown on fuel additives and additive packages added by the brand. Shell and Chevron both seem to go above and beyond when it comes to putting in more than just the minimum required. I'm sure there are others. Your video covers all the bases and it's truly well made. Thanks!

Shell Employee: Have you seen the strange guy that keeps coming back to pump number 6 in different cars to talk to the pump?

My engine thinks it’s a comedian but I don’t like knock knock jokes

I know ABSOLUTELY ZERO about cars, my 2006 scion is starting to give me problems and this channel has been extremely helpful! Not a car enthusiast but you got a new sub because your videos are easy to follow.

Good video! I had a ‘95 del Sol DOHC VTEC and still one of my favorite cars I’ve ever had, nice to see one still looking good!

Did you notice during the montage of cars, the tires were parked in the same exact place? Guys a perfectionist

*Gas attendant looks out the window* "That guy with the camera is back with another car."

There is a reason why ChrisFix has so many subs, I don't even know about cars but I'm starting to get into them.

This video should be a must-watch for every first time car owners. 💪🏼

“I put in diesel to save money” -Michael Scott

Oh man $2.37 sounding really good right now

We generally only have 2 different grades in the UK. I've only ever bought the higher octane when I had an RX8. Was always told high octane is just for sports cars. Now I know lots more on the subject. Great video as ever.

Love the video, this has cleared up my confusion on which fuel to use for my SUV. I was trying to go cheap (87 Octane), but realized that I have to use at least 91 and above 💪

"She can take regular all day long" -Chris fix 2019

Imagine driving and seeing a guy recording and moving his hands a lot. And the people getting gas. "Can this guy just get his gas?"

Wow how long did it take to make this video so clear very specific, this guys deserves everyone credit ….. thump up 🆙 for you man.

Shell costs a lot more compared to other gas stations in my area but its good to know their fuel is much better and has more additives 😊

I've gone to bed every night for my entire life wondering what the difference is between the gas numbers. I can now sleepy soundly at night. Thank you.

Just realize he had to drive every single one of his cars to the gas station for a 4 second clip. Respect

Excellent tutorial video, thank you for clearing some areas about what type of gas to use😊 keep up the good work

Holy crap thanks for making this video. I daily drive a Toyota Camry 97 V6 and I’ve been noticing some poor fuel mileage and less power. I may replace my fuel injectors as I had to do with the sparks as most of the parts when I got the car were from out of factory production. But I will try and look up if the pro gas will help clean my engine or not. Thank you 🙏

Before video: I know nothing about cars... After video: I'm a mechanic.

Chris is the type to point to his mom when he talks to her.

Great information, great video! Loved the animation and all of the explanations...very thorough!! This is one of the most informative videos I've seen on UKposts!!

This was a fantastic video explaining octane and which ones you should use and why.

No one: Chrisfix: 👌🏼👍🏼☝🏼👈🏼

The first 30 seconds looked like a car selection screen for a game😂

Man you don't know how much you just helped me ! I feel so good that I just learned so much watching this video. I'm going to Shell when I leave work today !

It’s crazy how 4 years ago gas was in $2 range.

This man deserves everything he has

As a Californian, seeing your gas prices made me almost cry

Wow, your approach to doing this video is awesome. Just clear and straight forward and well thought out visuals. well done.

Had to sub on this guys content. His knowledge, information and demonstration deliverance was impeccably detailed, organized and smooth. Very interesting & attention grabbing video content...👍🏾

The fact that he brought all the cars to the gas station in the intro just shows his dedication

ChrisFix *walks into shell* Teller: Hello how a- Chris: Hey guys! ChrisFix here!

I can see the dedication in this video. Deserves a subscription 👍🏼

In Norway we have 95E10 and 98E5. 98 is actually ethanol free in Norway, but due to EU regulations we have to label the pumps with E5. The reason why we have 98 as ethanol free is because we have a lot of older cars that usually are parked during the winter. E10 is not good for older engines, and specially if the vehicle is parked during winter. Now we are working on getting 98 into more stations, as more and more people use it.

Chris fix is trending. Nice job, you've earned it!

Chris really traveled all the way to Europe to compare the fuel ratings

Thank you for helping dispel myths. PS - I tried to run 87 in my Jaguar (premium required). After a year, I had to change plugs and coil packs. Switching to 92 fixed the issue.

What a video! I knew these things and I still watched till the end.

This guy made me read the owner’s manual of my car.

I'm a chemist and have worked in a lab testing gasoline and diesel. This is for the protection of the consumers in our state. I'm pretty sure most states have a lab to do this. Most of the information in your video is correct and very useful. Thank you for making sure to emphasize the octane rating you see at the pump is NOT the energy content of the gas. It's all pretty much the same between 87 and 93, unless of course it has a higher percentage of ethanol (Uh can we say E-85? why would someone run this fuel 🙄). Ethanol will decrease the amount of energy in the gasoline, but it's added to make the gasoline burn cleaner and is good up to 10%. Something you didn't emphasize enough though is what "octane rating" actually is. It is NOT the amount of octane in the gasoline. There is little to no octane actually in gasoline (octanes are eight carbon hydrocarbons). The octane rating is the "equivalent amount of octane" in the fuel so that will resists knocking as if it contained that percent of octane. Gasoline is mostly made up of mixtures of toluene, and xylenes. If you ran pure toluene as your gasoline, you'd be getting about a 110 octane rating, but this wouldn't necessarily be good for your engine. When gasoline is made, the manufacturers control the mixture of hydrocarbons to get a clean burn and the proper vapor pressure (vapor pressure is the pressure of the vaporized gas above the liquid, not to be confused with the engine pressure). Also the gasoline must be protected from oxidation (this is why you add fuel stabilizer when storing for a long time) and contamination like water or particulates. Every brand of gasoline has slightly different proprietary ingredients to do this (as you've said at about 6 minutes). Also, the time of year will dictate what vapor pressure the gasoline manufacturers must make the gasoline to deliver to the consumer. Forget octane boosters. A pint of octane booster won't raise the octane rating of a full tank of fuel enough to make a difference. If you have a high performance engine that's been engineered for high compression, you're going to know you need a higher octane rated fuel. You aren't going to hit that 87 button. Are you?🤔 By the way, most mid-grade pumps, mix (in the pump itself) two parts of 87 with one part of 93 to get 89. But if you look at the price per gallon, they usually give you the "mid-price" between 87 and 93 for the 89. You'd be better off cost wise, by pumping 10 gallons of 87 and 5 gallons of 93 if you really want 89. I suppose mixing it well enough in the tank might be problematic for the first few miles. Really, you didn't need the 89 anyways. Octane Rating Tests Explained: One more thing you didn't explain well was how we get the octane rating in the USA. Yes RON stands for Research Octane Number. It refers to an actual test engine and ASTM method D-2699 for testing the octane rating of spark ignition fuels. My lab uses a RON called a Waukesha RON engine. It varies the compression of the cylinder to make the fuel knock while holding other variables at constant values (temperature, fuel/air mix, engine speed, etc). There is another test engine my lab uses, it's called a MON or Motor Octane Number engine and ASTM method D-2700. It too is a Waukesha engine that varies the compression of the cylinder but holds those variables at different values, mostly the engine speed is faster on the MON (900 rpm instead of the RON's 600 rpm), but I believe the inlet temperature of the RON is also kept higher. The RON and MON tests give slightly different results for octane rating due to the differences in these other variables. MON is always lower than the RON, by about 10 octane ratings if I remember correctly. In the USA, when you see the (R + M)/2 on the pump's octane rating label, it's telling you that the gasoline is rated by testing by both the RON and MON methods, and the final number you get is the average of the two test results. I rarely hear this average referred to as "PON", but I know it's not PUMP Octane Number. I had to look that up and if you want to trust Wikipedia it stands for "Posted Octane Number". In Europe, they only test with the RON method, as you've said, so this is why their octane ratings are higher. They don't have the lower MON test averaged into their octane rating. Great information in your video for all consumers. I gave it a thumbs up. 👍

Great presentation and very well spoken not to mention very useful content. Subscribed!!! Thanks for all the hard work you had to go through for us viewers. I see I'm a little late watching it but it still applies. Booyah!

Those gas prices make me feel so nostalgic.

"Less than $3 for a gallon of gas?" *Cries in Californian*

Shell Premium V Power : $2.90 California Drivers : I haven’t seen those prices since 1874

Great video. Cleared up a lot of questions on what fuel to use.

Chrisfix: Thanks to Shell Shell: Turns into Speedway

0:16 when you're selecting your vehicle in mario kart

Thank you so much, You explained it soo well and the examples were Amazing!

I’ve been one of your biggest fans for years you are great at what you do.

This is one of the rare premium quality informational videos on UKposts. I actually felt sad when I realized the video was ending, not realizing it had been 16 minutes already. Thank you for your dedication.

Can we appreciate he drove all those vehicles at the beginning.

Thank you for clearing this up! Now the challenge of getting people to listen to me.

Thank you for settling the Recommended versus Required debate 😊

If there's one thing ChrisFix has taught me, it's to read the car's owner's manual.

0:14 Can we appreciate the fact that Chris drove all his cars to the gas station just to make this clip

absolute beast for making such an informative video!!

Excellent video. So grateful where i live i can get minimum 90 octane non ethanol gas. Love running the pure gas through my car. More expensive yes. Worth it yes. Put quality fuel system cleaner in once a month and the engine just purrs on down the road.

ChrisFix: *Talks about what fuel is the right one* Me: *"Diesel, shaken not stirred"*

as a californian i’ve never seen those gas prices

man you really took the time to show the details. much appreciated

god only knows how much ive missed $2.37/gal

After watching this video, I started pumping diesel into my Toyota Prius.

0:14 There's more cars showcased here than there are in any Need For Speed games

The best explanation about the differences between gasoline! Great Job and great animation, though. One more sub!

That was actually very interesting and superbly put together

He literally flew to Europe just to show us a gas pump there. That’s dedication

Lowkey re-watching this in 2021 just so I could time travel to the days when gas prices were in the $2.30 per gallon 🥲 now im paying 4.75/gallon

Great job C! I’ll look at this for my 2014.

Very informative! Thanks for the video

Finally somebody that knows how to hold the camera straight. His narration was great the audio was great the video was great the information was great just an overall solid piece to put up on UKposts. 100% two thumbs up for this guy. Keep them coming. Maybe you can put something up for a V6 Mustang regarding power adders.

The answer is simple: Use the grade of gasoline recommended in your vehicle's manual.

This video was really really helpful I never knew about this.

Love the way he break down the information on his videos. HOPE WHEN HE ITS 10M SUBSCRIBERS, TAKE OFF HIS HELMET! Keep doing more videos for use

Judge: 47 years 69: I know what ChrisFix looks like in person.

Shell: V-Power gives you more performance! Chris: *that is completely false* Shell: bruh...

I use regular 95 octane but once in a while I use 98 octane with a bottle of injector cleaner and fuel system cleaner just to make sure everything works as it should. I had a problem with my engine getting extremely weakened and losing power but after the injector cleaner it runs smoothly and feels much more powerful and has much better acceleration now compared to before

Great video great transitions very informative. ❤

chris fix: *brings 14 cars to the same pump* cashier: "why this man got so many cars and how he drive all of them so much?!?"

Chris getting $2.39 a gallon over here in Cali we’re paying $3.99

Very helpful video and great explanation! Thank you!

thanks for another amazing video chris. i have a turbocharged volvo so this video rly helped

Glad to see The Stig staying active in between seasons of Top Gear.

This video as of today was posted around 4 months ago and Man is still giving comments hearts and replying props to you

Well done! @chrisfix I love all your videos!! I have a 1972 ford v8. Should I run a “ lead substitute “ in regular octane? Or should I run 93 ? Or…!

I know from personal experience about Shell. I drive a Ford with a 3.0 engine which runs on any economy fuel. However my girlfriend has a 6 cylinder Jeep she bought new. She was having problems and the dealer told her it was the fuel pump which was "starting to go". This Jeep already had the transmission replaced at 3 months and head gasket at about a year. This was her work vehicle and they quoted 3-400 for a new fuel pump installed. He jeep was fuel sensitive, the additives used in our town didn't work too well, but the next town north(different distribution point) worked better. I suggested she try the Shell economy fuel, it was the same price or 2 cents more to see if there was a difference. She tried a tank and there was no difference, on the second tankful the problems went away. It ran better and her problem fuel pump lasted another 6 years.She still has it, going on 20 years and she had to stop using Shell, n stations around here anymore
