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

  • Published: 15 October 2019
  • 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.

    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: https://amzn.to/31kHwhk

      this isn't really related to this video but one of my cars rear speakers is busted and i can't figure out how to get the panel over the speaker off. i have a 2008 Pontiac g6 gt 3.9l v6 hardtop convertible. i dont have the owners manual and have looked all over the internet for videos and nothing. i have even been on a Pontiac owners forum but they weren't much help. i was wondering if there was anyway you might be able to help with my problem? if not its cool.

      ChrisFix great video! I wonder if you could every do a video on exchanging transmission fluid on a sealed transmission like on a 2008 toyota tundra 5.7 with no dipstick from the manufacturer. Thanks!

          Great video! For those of us that need to run Premium, my (informal) testing shows three brands that work really well (Shell VPower, BP/Amoco Ultimate and Sunoco Ultra), and others that don't work well at all (Mobil, Exxon and generics). My 2005 Saab 9-5 Aero has a high-output factory turbo, and requires 93 Octane fuel. It also has a Trionic engine management system (so it can anticipate knocks and dial back the boost and spark advance to prevent detonation, and allows temporary overboost if the fuel is good enough). My winter driving (from the NYC area to the mountains of New England) is great for testing - includes consistent fast highway driving and big hills. If I'm using anything other than the three brands listed at the beginning of this post, my car a) gets lower gas mileage, b) has less power going up the hills (have to downshift when I normally wouldn't have to), and c) won't allow overboost. Where I live, Shell V-Power and Sunoco Ultra command a higher price that Amoco Ultimate from BP. The V-Power generates more power/overboost, while Sunoco Ultra provides slightly better gas mileage. The Ultimate does neither (but car runs absolutely fine) at a better price point. Note that my observations may play differently on cars without a Trionic system or overboost. Enjoy.

                E-85 (FlexFuel) vehicles will typically have a FlexFuel emblem on the trunk lid or tailgate.

                          Amazing video Chris! I guess i cant even imagine how much work you put into making this video, moving all those cars back and forth and making those animations. I just started my own car fix channel and it takes alot of work just to film a simple oilchange. There is so much extra work with moving cameras, camera lights running out of battery, people coming and going, etc etc so something that normally takes 30 minutes takes 3 hours instead. Keep up the good work! I dont know whats up with the helmet but be who you are, you are above all anyways!

                          Alot of love

                                Putting an additive like corn/ethanol is makes the gas mileage go down! High octane sales pitch is that they offer no ethanol blending.

                                    My 2016 gmc Denali 5.3 uses 93 octane to pull a trailer. If I use 87 it will detonate. I don’t get better mileage by using 93, actually worse, just smoother performance at redline with 7800lb going up a hill.

                                                  In my country there is no such thing as 87, we only have 89 (95 and variants) and 93 (98 and variants). We don't have the ship stuff... :'( *cries in Octane*

                                                    My 2004 BMW 325i was only getting 15 mpg and always had very low power.
                                                    I had this car for 3 years.
                                                    I put some fuel injector cleaner in the tank. Didn't notice any difference.
                                                    However, after a while on the next tank full it suddenly had what felt like a Doubling in power!
                                                    It actually pushes me back in the seat now.
                                                    I haven't checked the mileage yet, but I assume I should be getting around 20 mpg or more.
                                                    I didn't think it would really make much difference.
                                                    For around $10, it's worth trying.

                                                                            I appreciate the steering wheel clock video.

                                                                            But I know a lot about Priuses after having so many of them.
