    1. Pick any oil, I ran rotella and valvoline just about every oil change, they are normally the cheapest. I'd stay away from penzoil. since you live down south, you could run 10w30 if you wanted aswell.

    2. I run napa filters, basically anything that is a wix filter works good.


    3. Either Ac delco plugs or auotlite 606's, just remember that the 606's only last about 15k miles because they are copper cores.

    4. Ac Delco wires are like 30 bucks off rockauto, to me they are the best wire for the car and cheap enough.

    7. Trans fluid is Dexron 3 for that car, I wouldnt run anything else in it personally, you will need 7-8 quarts with a pan drop.


    8. For anything else just check over small stuff. Perhaps replace the PCV, new fuel filter and check to see if teh intake gaskets and coolant have ever been changed.
