What is the BEST Fuel to Use in Your Car or Truck and WHY

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

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

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

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!

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

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

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

The gas price 4y ago 😭😭😭😭😭

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

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 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.

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!

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

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

Damn ChrisFix, normally i don't take the time to put a comment on a video.
But i watched so many of yours, and every single one of them has an explanation that makes me understand it!
So much effort goes in your videos and this can not go unnoticed.
Thank you for sharing your knowledge you genius!

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.

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

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

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.

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

Oh man $2.37 sounding really good right now

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 💪

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 😊

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

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

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!

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

*Cries in Californian*

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.

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

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

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 !

Thank you so much! I didn't know about octane boosters!
I need medium octane in a vehicle I rent out and you wouldn't believe how many people just put the lowest octane in it even when I remind them that it requires medium octane.

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?"

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

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 🙏

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 KRplus!!

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

No one:
Chrisfix: 👌🏼👍🏼☝🏼👈🏼

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...👍🏾

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

This man deserves everything he has

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.

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

Drinking game: take a shot of gasoline every time Chris says “Octane”

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

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

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

Chrisfix: Thanks to Shell
Shell: Turns into Speedway

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.

Tell us about the 85 octane we have in high altitude areas. I have heard that this was to compensate for the lower atmospheric pressure, which results in less compression in the cylinder, and thus less tendency for knock. But I also heard that this was first done in the days of carbureted engines, and these days nearly all engines are fuel injected. The car manuals all say to use at least 87 octane. Do we really need that higher octane at a mile high or not these days?

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

Diesel owners: I only have 1 choice.

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

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.

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

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

It literally depends on the vehicle you have. The only car I've ever had where you could tell the octane made a noticable difference was a 2017 Sr turbo nissan sentra and it picked up a few ponies with 91 octane no doubt. That might be true of all turbo/supercharged cars and unless the vehicle is tuned for the fuel, it'll only be a small difference but will burn cleaner.
I'd say any car that has a 4cyl or 6 banger with 300hp should use 91, and any v8 over 350hp should use 91, especially since those hp nunbers say you have a $40K+ car, why settle for less?
My first car out of high school was a built 87 Lx mustang converted to mass air and had a gt40 crate motor from ford with all the goodies and it was tuned for 91 so I always used it, of course this was in 2005 when even 100 octane was only $5gal. I ended up putting a low compression 331 stroker in it but it was untuned so I ran it at just under 30 degrees of timing and it loved the 91. The 100 octane didn't help much because it was built for boost with such low compression soo when I was low on funds or was going on a long drive, I would bump the timing down and put 87 in it and it wouldn't run funny.

Thank you for settling the Recommended versus Required debate 😊

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. 👍

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

absolute beast for making such an informative video!!

I use premium because i do not drive but maybe 150 miles a month. I use sta-bl fuel additive to save the life of fuel.
I do have higher use from time to time but 80% of the time is 150 or less miles. I bough a used ford explorer in 2012 with 197686 miles for $1000. It had not been taken care of. I fixed the problems it had. Front end comletely replaced. $575 in parts. Saved $1000. Drained all the fluids including the gas tank. Changed all the belts and hoses. Cleaned the fuel system, replaced all the bosch platinum plugs and wires. Fixed intake leak in gasket. Vacvumed car and washed it. Paint was in bad shape when i bought it. I stripped the paint and repainted with primer 5 coats and 4 coats of clear coat. I did it myself. I saved $1500 new tires and bought tire covers. The vehicle by blue book is not worth but $2000. But this Explorer is in better shape than most newly boight vehicles it gets 23 mpg and 14 city. Owners manual says its duppose to get 19 hwy and 11 in city.
If people would just take care of their vehicles they will last.
I don't have thousand of $ in tools either. I have good tools that are good enough for the job. If my parts are stress parts a bought better quality tools for those parts. I may have a $1000 in tools $400 just for a tool box to hold them. I do all my own repar work on both my vehicles my second carcis a 2012 Dodge Grand Caravan bought for $2000 cash. It needed drivers sliding door repaired. Did it myself and saved $1100 dollars in repairs. New alternator save $ 525 in repairs good qualty tires saved $1500. Shop around. Deals are out here. Had TIMP defect from factory. Repaired it saved $1400 oil pump saved $400. Both vehicles run and drive like new.

0:14, tell me this doesn't look like selecting a car in a video game.

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

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

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

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

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

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

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

Felt like i just did some cheat codes on grand theft auto for the first 25 sec of the video 🤣 nice video tho chris , keep up the good work

god only knows how much ive missed $2.37/gal

great info ! I only use 87 octane but it does say , premium recommended . my question is , would it be a good idea to put in that octane booster once in awhile to help keep my motor running smooth and clean ?

Dang looked like I was at the arcade choosing a car to race in lol

as a californian i’ve never seen those gas prices

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

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

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

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

Wow. This was incredibly helpful

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

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

Honestly, this is such an excellent video, I’d never known a lot about cars and your videos really have helped a lot!

Very informative! Thanks for the video

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

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 KRplus. 100% two thumbs up for this guy. Keep them coming. Maybe you can put something up for a V6 Mustang regarding power adders.

Hi Chris fix um I love all of your videos❤they are the best!

Great video great transitions very informative. ❤

I need those gas prices here in California

Chris: And you don’t want engine knock”
me: *looks at my subaru*

As a KIA mechanic around early 2000, there were many pinging issues here in the south. Fuel door claimed “87” but they needed 89 octane to prevent knocking… at least that was how well they built them for the US then.

Very helpful video and great explanation! Thank you!
