What the f*ck is wrong with you you simple minded moron? We have already played this silly ass game with you. No matter what you think, running gasoline with a higher octane rating than your car requires WILL NOT INCREASE FUEL ECONOMY
! Your Hyundai is optimized to run on 87 octane. Using higher octane gas is at best a waste of money and at worst can actually cause you to lower your fuel mileage and cause damage to your catalytic convertor.
I don't care what you think. This has been tested over and over ad infinitum by manufacturers, oil companies, private research firms, car magazines, etc. Unless you want us to believe the you are the one and only person on the face of the earth that sees decreased consumption when increasing octane in an engine that isn't designed for it, then just STFU... Moron.
