Using an octane rated higher than your vehicle?

HERE THE ANSWERS 👇

  • A

  • Using An Octane Rated Higher Than Your Vehicle

  • Using higher octane than required gasoline will simply cause you to spend more money than you need to on gasoline. The answer is A.

    Now, you may see some temporary improvements with the way your engine runs if you do use high octane gas. That is simply an indication that you are overdue for a tune up.

    It won’t burn your heads or give you any more power. Back firing is a function of timing and/or valve wear.

  • If your vehicle is properly tuned (i.e. correct ignition timing and advance curve) then A is the correct answer. But, if the ignition timing is slightly more advanced and the higher octane fuel is used, there may be an noticeable increase in available torque throughout the power range. This power increase comes at a cost!! Increased intracylinder (flame-front) temperatures but only if you leave your foot on the floor too long.

    Should ya do it?

    If ya can’t stand the heat . . . .don’t race

  • E. None of the above. Octane ratings for your vehicle are determined to

    prevent pre-ignition or engine ping/knock. The higher the octane the slower the fuel burn, which reduces spark knock. Higher compression

    engines will require a higher octane fuel, ie.. race cars with 13 to 1

    compression as opposed to a stock engine with 8.5 to 1 ratio. In the winter time a car with lower octane fuel will actually start easier than the

    same vehicle with a higher octane fuel.

  • The octane rating for your car is the minimum that the manufacturer says it is to be run on. Increasing the octane level does increase the power slightly but it may not be worth the added cost.
