This Site Might Help You. RE: Do automotive oil additives really protect your engine? From STP oil treatment to Slick 50. Do they work?
you are responsible for the smog you bought it as-is, and most auto zone places will not erase the codes at least in Arizona its against state law. also like others have said start with the lowest cost part, emission controls on vehicles can be costly this is probably why the vehicle was in an auction to begin with.
You have found out why it is not a good idea to buy an auction vehicle.start with the least expensive repair (a new fuel cap) and go from there to the next least expensive item; you will probably need to keep going back to autozone to have them clear the code, then wait a day or so to see if the code /light reappears PS while at autozone, have them show you each part that shows as needing replacement
1. check the fuel cap, it might be loose, tighten if needed 2. if that does not solve the problem, try a new one, they are cheap. 3. otherwise, you will need to take it to a shop for further testing.
My father has been a mechanic for over 36 years. He had previously rebuilt a motor on our pickup. We had been running Mobil 1 Synthetic oil and had also put in Slick 50 once. He said that the inside of the engine looked extremely clean and almost new in some areas. We put Mobil 1 in a few other vehicles. In one of our pickups, it seemed to start using (burning) the oil afterwards. We didn't worry too much and simply added what it needed between oil changes (every 5000 or 7500). We never had problems with those engines.
