Could I get away with puting regular gas in a pontiac grand prix gtp?

Question

or at least plus?

Answer 1

if the manual states that premium is required, then you cannot. higher grades of gas translate into higher detonation resistance. if you use an octane that is too low for your car, that can result in detonation which can cause engine failure.

Answer 2

Bottom line, no. You should use whatever the manufacturer says to use in it. Yes, the computer will try to compensate if you downgrade the octane, but that will lead to at best a loss of power, and at worst a knock which will lead to engine damage.
