A Qucik Question...

I got my 95 LHS two weeks ago...and my dad filled it up with unleaded. I've been reading around and people suggest to put in Plus, because its an older car and so on and so fourth. My question is, I am going to need to fill up my tank soon...should I wait until like my low fuel light comes on again...because right now its abuot 1.5 notches above E...or do I have to go as far as draining the tank out or something?

Please help...thanks. Sorry for the stupidity... :(

Midgrade or "Plus" Gas (89 octane or higher) is the minimum requirement for the 3.5 Liter engines because of the compression they have. The engines do have knock sensors that will retard the engine timing if they detect a knock just in case the owner does fill the tank with regular unleaded. It won't hurt anything to run it but you may have slightly less performance or mileage with that tankfull. When you need more gas just fill it up with the 89 octane gas and it will be just fine.
