Well...I haven't tried the oil supplements , but My dad has tried the Lucas one and he says it works, and my uncle says so does the STP....So...I guess It's just One's decision on which brand to use.

Has anyone tried some of the various oil and fuel supplements? There are several oil supplements available from STP, such as the 4-cylinder oil treatment. Some guys down the street swear by Lucas oil. Any recommendations? I have a 77 CVCC engine.

Thanks,
Rob
