Outstanding product. Engine runs smoother, spools up faster, Valves & Guides running clean, better gas mileage.But a bit pricey!
Reports show zMAX works
From S. Norquist of Los Angeles, California on .
Hello, I wanted to give you a report about my use of zMAX engine treatment. I have a 1998 Ford Escort ZX2. It currently has 272,000 miles on it and is still running strong! For the last 146,000 miles I have added zMAX engine treatment to my oil every other oil change. I change oil every 3000 miles. I recently sent a sample of my oil into Blackstone Labs to see how my car is doing after so many miles. The oil report showed that my car fell well under all the base levels of wear. Also my emissions always test very, very low and surprise the testers. Can I attribute the low wear and low emissions to religiously using zMAX? Maybe so. Here is the summary of the oil report from Blackstone: STEVEN: Thanks for letting us know about the zMAX. That additive won't show up in our testing, but some do, so it's always a good thing to mention. Your Escort really isn't making much metal at an impressive 271,835 miles. Of course, the universal average interval for these engines is about 6,300 miles so low wear on a shorter run is good, but metals are still low enough to show that the oil-sharing parts in this engine are getting along. The TBN is 4.2, which is well above our 1.0 lower limit for that test. Check back with 4,000 miles on the next oil change to start trends.
Worth every penny!

I am impressed with zMAX! Great Product!!! I have been working on and driving motorcycles, hot rods, off-road trucks to family vehicles for 50 years. I have tried many products that make claims that are, in my opinion, rarely met. I took notice of your product zMAX from a commercial on one of the car rebuild/auto programs. I have been having a serious noise problem with the steering pump on my Dodge Grand Caravan for over four years. These pumps are notoriously noisy. I tried everything to no avail. The next step was to replace the pump at a huge price tag. I paid what I thought, at the time, was a lot of money for that little zMAX bottle. I replaced about 6oz of steering fluid with zMAX. Started up the engine, turned the wheel back and forth 5-6 times and it got quieter with every turn. I drove the van around the block and by the time I turned into my driveway, the noise had completely stopped and the steering was a lot smoother and easier. I am a new fan and believer. That little bottle was worth every penny!!
Lifter ticking gone
From Anonymous of Knoxville, Tennessee on .
I changed my oil and added a bottle of zMAX to the fuel and to the engine oil and within a few days my cold-startup lifter ticking was gone. No other additive, flush, oil or filter combination was able to achieve this. Excellent product!
304,000 miles and going
From S. Brown of Sacramento, California on .
I have used a bottle of zMAX Engine Treatment faithfully with every oil change since I got my 1991 Chevy Astro Ext. cargo van in late 1996. It had 98k miles on it. 3 changes per year x 17=51+2=53 bottles. 53x$30=$1590 in zMAX. My van now has 304,000 miles!!! Great investment!
