Great Product

This is a great product. I have been using it for years and it does make a difference.
HEMI POWER
From ROBERT LUTGEN of Highland Park, Illinois on .
I take special care of my truck and was impressed with the guys on “TRUCK U” showcasing ZMAX. For me I feel increased throttle response and smooth engine performance. I have stock exhaust and the only way I can tell my engine is at idle is by observing the tachometer. I my be a Chrysler fanatic but my HEMI has never been this smooth.
A must have
From Anonymous of adkins, Texas on .
Worth every penny, I have used on my personal vehicles since 1998 and works the same today as it did then.
Don't be without it.
From Ralph of Grand Blanc Twp, Michigan on .
Have been using this product for years. Once the oil drain plug washer was left out and all the oil leaked out on an hour and half freeway drive at 75 mph. When I exited the freeway the oil pressure gauge went to zero. The engine temp never got hot, did not hear any tapping noise from the lifters. ZMAX truly protected my engine. I will "NEVER EVER STOP USING IT." Have a 1999 Ford Ranger with 289,000 plus miles, engine runs smooth and quite as day one.
Response from zMAX: Awesome that your engine was protected by zMAX. Thanks for being a zMAX customer!
