Has anyone ever tried any of those engine oil/ tranny additives like ZMax or Prolong? I work in R&* Strauss in Jersey and hear that stupid infomercial all day, and was wondering as to their effectiveness.

Zmax is nothing but Kerosene. They're in big trouble with the FTC for false claims.

Thanks for that one. Looks like I really dodged the bullet there. My friend bought it and refilled the bottles with water and food coloring, and returned it at another store....got his $39 back, but it looks like that'* gonna go towards fixing his engine in a little while....

i have put that "restore" in my oil after i changed it...i noticed right away had a little better run to it cuz it "supposidly fixes compression and blah blah...but for some reason my car seemed to run a little better...and its BLUE!!!!!!!!!!!

David, that'* the ONLY mechanic in a can that I reccommend. That stuff really works in the right situation. Valve stem seals and scored cylinder walls can benefit from it.

Hey David,
What'* it called and where did you get it?
Thanks in advance,
Stylez

Aha! Now I know what you are talking about. Last time I used something it was the valvoline stuff. That stuff worked awesome I thought. I might try them both (on different oil changes of course) and let you all know which I think is better.
