gasoline question

[adamrobert79]

ok so I need to know if its ok to run a full tank of plus unleaded in my car and then switch back to regular unleaded.

Need more info plz, is the car NA or SC?

If your Naturally Aspirated(NA) then you can run whatever your wallet can afford.

If your Supercharged(SC) then you need to run 91-93.

it is not SC. that I know. well whats your opinion on running premium all the time. will that effect the engine since I have been running it on unleaded for the past year?

Running premium in a NA GP is a waste of money. Octane is just knock preventer. The more octane, the harder it is to burn. The if it doesn't burn right, you will lose power and gas mileage.

Sure thing little buddy.

A higher octane isnt harder to burn, just harder to ignite becuase of its higher flashpoint. The burn time is also slower compared to lower octane fuel.

Running premium will not affect the mpgs or anything in a NA 3.8. At WOT you'd see less kr and more power because of what the fuel does.
