I HAVE BEEN USING ZMAX SINCE IT CAME OUT AND WILL TILL I CAN'T DRIVE. LIKE ANYTHING GOOD IT BECAUSE PART OF THE ROUTINE AND I HAVE HADE 3 CARS COMBINED WITH THE ZMAX AND MOBILE ONE SYNTHETIC THAT HAVE GONE 250000 AND BETTER ALL LOOK AND RUN LIKE THE DAY I GOT THEM. STAY UP TO DATE WITH SCHEDULED MAINTENANCE AND KEEP THE FLUIDS CLEAN AND YOU CAN LIVE PAYMENT FREE FOR A WHILE. USE IT IN THE YARD EQUIPMENT ALSO AND THEY ARE LIKE NEW ALSO UNTIL YOU GIVE IT TO YOUR SON-IN LAW.

Highly Recommended

It's great! I'm on a fixed income but I've been using it in my vehicle for almost 10 years and my engine runs like the day I bought it.

Response from zMAX: Thanks for being a longtime zMAX customer!

Still running after all these years
From Ralph Spinelli of Effingham, New Hampshire on 7/19/2019.

I can honestly say that this product works. My oil light didn't work after I had my oil changed at a dealership. They forgot to put oil back in my truck engine. I drove my truck home which was over 100 miles. Then the oil light came on I checked it only to find NO oil in my engine. Thanks to zMAX my engine was okay and it is still running after all these years. Thank you, Ralph.

Response from zMAX: Glad to hear you had no damage in your engine. Thanks for being a long time zMAX customer!
