do i have to run synthetic motor oil in my 93 or is conventional oil ok? the reason i ask is since i bought the car i have run synthetic oil in it. right after buying the car though, i ran it for about 1,ooo miles before changing the oil. during that time the car didn't smoke that i noticed. since i changed oil and ran synthetic it has been burning oil and smoking. is this coincidence or could it be more prone to because of the nature of synthetic? also, if i need a rebuild, and it is out of warranty, where would you recommend, say, east of the mississippi? Where would be the best source for rings, pistons, etc. thanks a lot!
