Z-Max?
Does anyone have any experience with an additive called Z-Max? I have a friend who swears by it and I was wondering if anyone had any experience with it. Any thoughts would be appreciated. Thanks.

I'm only aware of one additive that Porsche has said is OK to use, and that's Techron, made by Chevron. Directions on the bottle, use the larger bottle for a 20 gallon tank. It is a fuel system/fuel injection cleaner. I use a bottle each spring to clean off the deposits that can form from MTBE additives in our local gas.
