Hey guys.....just curious on the product called Zmax. I know that the others like Duralube and Slick 50 are not good for the performance engines because of the teflon...but I was wondering if anybody tried Zmax and their opinions...Just curious because I just saw it on TV again and figured I would ask.

 

Don't.

Personal note to you - avoid any additives to any performance engine if possible. If your having trouble with your engines performance, try adding BG 44X or GM Top Engine Cleaner to the fuel at fill-up. Give it a while to work, and check your fuel filter after your next fill up. Carbon can cause a lot of fouling and loss of performance. But as for other additives - We could say the cure can be worse than the disease!
