Highly Recommended
From Michael Christie of Saint James, New York on .
Noticed within one day my engine running smoother,quieter,and better performance.
Amazed!
From A. Patel of Jacksonville, Florida on .
My 2010 Acura TL SH had been burning nearly 4 quarts of oil between oil changes, which resulted in a rough engine (especially when I was running low on oil). All the online forums indicated this could be normal, so I was close to trading in my car. On the way home from a business trip I sat next to a car expert, who recommended I try zMax to see if it would help. I added 1 bottle to the crankshaft and 1 to half a tank of gas. To my amazement I went through a whole oil change without adding any oil, plus my car runs like a brand new car at 140,000 miles. Thank you zMax!
Engine runs steady and smooth!

Ok, I want to start out by saying that I've tried many oil additives and fuel treatments over the years that claim to do this and that. Well today I decided to add the zMAX oil and fuel treatments to my 2007 Jeep Wrangler with 107,700 miles on the odometer. Before adding zMAX the jeep had a very slight lifter tick at every cold start up, which would go away after oil got flowing. I read the instructions and added your product as instructed and WOW!!!! I'm in complete amazement! Instantly the tick went away and the engine idles extremely steady and smooth, with zero noise! After being blown away by the results I quickly ran out and bought zMAX for my 2015 Chevy Silverado, my 87 Buick Grand National and my wife's 2011 Mercedes SUV. I will forever use this product in all my vehicles at every oil change! zMAX works as advertised!!!!!
Thanks zMAX!

Just wanted you to know how great zMAX is. I have 7 cars/vans and been using your product for about 12 years. I drive with confidence knowing I have zMAX in my vehicle. Thanks!
Your product works!
From W. Boedecker of Dallas, Texas on .
I just bought a new mower to mow six acres a week. I'm looking to get the same results as I do using zMAX in my Santa Fe. Just had the 100,000 mile check-up and still no valve adjustment. They said the inside of the engine still looks like just came from the factory. Putting over 80 miles one way each day, I can say your product works! Keep up the good work.
