What Does 93 Octane Gas Do?
The octane rating for gasoline has nothing to do with the amount of power locked inside of it. It relates to just how much a fuel can be compressed before igniting. The higher the number, the less likely it is to ignite under pressure.
More aggressive engine management schemes can turn up the compression to a high level. Sports cars tend to require much higher octane gasoline to avoid knock. Gasoline is sprayed into a cylinder by a fuel injector and mixed with oxygen. It should remain in vapor form until it is time for the spark plug to light it up. This causes the explosion that drives the piston down to generate horsepower. The timing of this explosion is critical. Gas that ignites too early causes ‘knock’. Knock reduces engine output and efficiency, and can damage an engine.
You won’t see a power or fuel efficiency increase by running 93 octane fuel in an engine that designed for Regular gas, unless you've got your car running an ECM tune for 93. Nor will doing so perform any extra ‘cleaning’ inside the motor.
Running low octane fuel in an engine built for Premium can increase the risk of engine damage, and will impact performance.
Find93.com recommends you follow the instructions in your owners manual regarding what kind of fuel to put in your gas tank. 91 or 92 octane is a decent substitute for people who live in California or remote areas where 93 octane gas cannot be found.
