Just bought an 89 'Stang. Need Mod advice

[Phantom5oh]

Synthetic oil is good and might be worth a few, but don't use a blend. They aren't worth it. The blends are like 5% synthetic, 5% chemicals, and 90% regular oil, with modifiers so it can work with the synthetic. You should never mix the 2!!! The blends do thier job well, but aren't any better than regular oil or synthetic alone. If you use regular oil use 10-40, 5-30 is too thin for a hi po V8. Bosch plugs are very good if you like them use them, they are good. Fram filters are ok, thats what I have, they are good for a cheaper filter, one of the best cheap filters. But they are cheap and easy to find. Hope this helps.
