My friend has an '01 Cobra he just bought. It immediately starting knocking a week after and now he's wanting to trade it in instead of replacing the motor. Question is, would adding some 80w90 or 74w140 fix the problem and make the motor quiet enough to go trade it in at a dealership?
I realize this is pretty dishonest but he financed the cobra and doesn't have the money for a rebuild.. so he's between a rock and a hard place. Just trying to figure out what a temporary "fix" would be.
I can't remember if '01 32 valve Cobras take 6 or 7 quarts.. but how many quarts of gear oil vs quarts of 5w20 should be added if this is an option?
