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

Ever wonder what grade gasoline should you use in your car (what octane)? Are you paying for premium gas when you can just use regular? Are you using regular and damaging your engine? This video will bust all of the myths and tell you the FACTS on what fuel you should use and why.

Many people throw money away and fill their car with the incorrect fuel every day. Running premium or midgrade in a car designed to run regular is a waste of money and has no HP or MPG benefits. You will not make more power or get better fuel economy running premium fuel if the car manufacturer tunes the car to use regular gas in most cases. I also see some people run regular gas in cars that need premium and the knock sensors have to adjust timing significantly to prevent damaging engine knock. I also hear a lot of people say that premium gasoline has more energy or burns cooler or slower so I will put a rest to all of these "myths" with facts.

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.

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

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!

[westonpotter]

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

[Curvee]

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

[stankybudz]

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

[Skeezitts]

my manufacturer recommends regular but ive always put premium in my cars and it feels like it runs way better with better power regardless.

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

[perlamiseriaccia]

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

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.

[dirtydingo]

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

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

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!

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.

[Darkstar]

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

[QsPracticalNonsense]

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.

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.
