you’re only wasting your money with the higher octane on that p.o.s. stick with the 87…
all the octane we have here is 87 89 and 91
it won’t harm your car it might even help it
You won’t tell any difference.
903 is the size of the old Fiat Abarth engine – same block, but in your car different heads and pistons, con rods, and crankshaft. Your motor should be very happy running on anything fom 87 to 90 octane, 87 being “Regular” gas. There is no real advantage to going to a higher octane number. If you find that under heavy accelleration the motor ‘knocks’ a higher octane might help – but you’d be much better off to just check the ignition timing and set it up to run on 87 octane. Saves a few bucks, and face it, your beast is not a dragster and doesn’t need premium gas.
It won’t hurt it but will cost about another .10 cents a gallon.
