Using 91 because it's "cheaper" is just false economy, or for those too lazy to work out the real numbers. |
LOL. If the engine isn't designed to run high octane fuel you will not benefit
from extra mileage. The fuel doesn't last longer. Tests have proven this.
If the engine has been modified to benefit from high octane fuel then you
should get more power from the expensive fuel.
If you have a stock engine that doesn't require PULP then I beleive it is a waste
of money buying the premium fuel.
