zMAX Multi-purpose Formula

Box was oily it looked like the product had spilled out but for the most part it was ok I would've liked also if I was notified when they dropped my package at the door cause people steals packages

I have used this on many vehicles. I always believed it was worth it. Just purchased a newer vehicle and put it in. My gas mileage increased by 1/2 mile per gallon, so far

Easy to use and better value than purchasing engine and gas treatments separately. Recommended and used by dealership but better value when purchased from Walmart. Keeps fuel intake and corrosion build up at bay.

always works great. never had an engine blow up or fuel issues. Great product.

use on all my vehicles

The one-quart bottle of Zmax is everything you need to treat an engine, fuel system, automatic transmission, and power steering. The package is marked, making application super easy. The product (I've used it before) does what it says it will do. The product was delivered right on time by FedEx. (shipped free).

Great product from Carol Shelby

Zmax is not cheap, but It works! My engine has 410,000 miles and still runs great! I have been using zmax since truck was new!

The product is Great for your Vehicle but the price for this in not. I went to AutoZone and bought zMax fuel and engine for less then Walmart. Com it was a waist of time ordering this.

I first used in 1999 when I bought a chevy cavalier with a bad motor, I had a junk yard motor put in that ran good but after a week or so I checked the oil n and the dipstick had burnt oil I couldn't even scrape off so I changed it to a better oil n added zmax and I checked the oil just a day later and the burnt oil was gone n I can read the dipstick, was clean as ever. it's an amazing product I've been using since
