I have used over 15 years
From David Cwodzinski of Sevierville, Tennessee on .
I have used Z-Max for over 15 years and am very impressed. I have had several friends that have shown up at my house with their vehicles shaking from poor performance that I have had them put some Z-Max in their oil. Within seconds their cars were running much better. Makes me look like a magician when I tell them how quickly they will see a difference. I now buy by the gallon to keep the cost down.

Awesome lubricant
From Nathan Oscarson of Union Dale, Pennsylvania on .
I have used this lubricant for over ten years and never had a problem. Great for cold weather and long life on internal combustion engines. It will clean your combustion and exhaust system .I just used it for my 2011 Subaru with code 51 It took 36oz to fix but was less than $585 for new cat.
Response from zMAX: WOW! That's great news! Thanks for being a longtime zMAX customer!
