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

      ChrisFix I know this is a late question, but, if there is a extreme difference in temp like a late or early winter, should I switch to winter gas if I filled up on summer gas before the stations switched?

    So 87 is you regular and 93 your premium? Where I live 95 is regular 98 is the good basic stuff and then comes 99 i believe wich is the premium here.

          i'm from Belgium and i'm surprised by the low price of gazoline.. Here we speak about liter and not gallon (1 gallon = 3,78 liters) so if we compare the price of 1 liter in America and Belgium, in America 1 liter = +-0.77 cents (euros) and in Belgium we have to pay 1.45 € for the same amount. That's crazy.

              We have 95 fuel, then 99-100, and over 104+. Why in america the gas has so low octane number?
              Even with your super octane gasoline, 93, at 3 bucks per gallon, at 45 liter tank, you pay 36 usd. and we pay double with the 95 octane fuel for a full tank...

                Octane is a number given to denote a fuel's resistance to turning to vapor.
                A fuel that vaporizes too easy for your combustion chamber design can pre. Ignite (ping)
                Or detonate ( knock)
                Just read your owners manual and question your dealership service department as required to stop your engine damage as you hear it
                They test local fuel to know whose works.
                Some brands and situations can cause issues .

                  Great video! I liked above! I am preparing to buy a 1970 muscle car which had high compression (for the day) , and it's also from the pre-leaded fuel days. Since it ran on leaded gas back in the day, do I have to use a lead additive? Maybe a rebuild of the heads with proper valve components would make it OK for modern unleaded gas?

                          I used to work for Wayne Fueling providing level 2 tech support for techs in the field working on gas pumps. A fun fact to save some money is that the mid grade is actually a mix of the premium and low grade gas. It's not 3 separate the pumps inside the fueling pump, it mixes the gas. Gilbarco pumps also work this way too. Chris is right about Shell stations. I've spoke with techs about the actual tanks underground and Shell is reported to be a lot cleaner in general, followed by Chevron. Be sure to never get gas when you see the trucks filling up the tanks underground. There is water in there that's measured by a floater and has to be pumped out when it reaches a certain level. When the tank underground is being filled that water gets mixed in and pumped through the lines if you're filling up, going into your gas tank. Best to drive to another station if you can. I say for $.50 a gallon and the longevity of your car, use premium. Hope these tips help!

                            What is the negative effect of using premium on a car that recommends 87 octane, other than price? I've heard people say that it improves their fuel efficiency, but I don't think you directly addressed this when explaining the actual differences between the grades. Also, what about topping off? I've heard it's a bad thing to do, but it seems like people do it all the time.

                                                                        I plan to go the BAJA route bigger injectors twin intake and headers & T304 exhaust with high flow fuel injectors & tune it they can tune it for anything right?

I also just installed new E3 spark plugs, put in high mileage oil, and replaced my air filter. Just trying to keep my car running at it's best. Please comment if you have an answer. Thank you!

I'm always curiose about if it really does clean out carbon deposits. I've always been curiose and there is no decent video that goes to your lengths of testing.
