Re: Another oil change completed......
that is the oil i use on my 1990. No smoke because 90's dont have exhaust valve seals, quiet, no chain noise at all and plenty of zinc to keep everything very smooth inside. I recently had some engine work and inside the engine was very shiney and clean. My mechanic said it looked new inside the cam covers and the cams looked great. I will stick with my high zinc mobil 1 for as long as I have my Z.
