For some types of cars, gas octane really does matter, and putting low octane into a car that requires high octane can cause problems. Here's how to fix them.
Accidentally pumping regular 87 octane gas into a car that requires 93 octane may cause the “Check Engine” light to come on. Although the car’s computer is smart enough to detect the pre-ignition knock caused by the lower octane and compensate by retarding the ignition timing, sometimes that’s not enough to prevent misfires and you can end up with a “Check Engine” light.
There’s an easy fix, though. Just zip on down to the auto parts store and buy a few bottles of octane booster. Follow the directions on the label for the correct amount to add to your tank. Then drive the beast and refill with 93 octane when you reach a half tank. The “Check Engine” light should go out by itself and the computer should return your engine to normal soon thereafter.
Avoid last-minute shopping trips by having all your materials ready ahead of time. Here's a list.
