I have used a bottle of zMAX Engine Treatment faithfully with every oil change since I got my 91 Chevy Astro ext. cargo van in 1996. It had 98k miles on it. Three changes per year x 17 = 51 + 2 = 53 bottles. 53 x $30 = $1530 in zMAX. My van now has 304,000 miles!!! Great investment!

I have a '68 Chevelle 496 Cl, Turbo 400. I push it to the limit on the track. In the past I've kicked rods out the side. Since I started using zMAX, I've had fewer problems. The fact that Carroll Shelby was part of this and Bruton Smith named a track after it, how could I go wrong? I use the oil, fuel and trans products in all my vehicles. A lot cheaper than replacing a motor, trans or injectors. Thanks for making a quality product.

325,000 Miles and Still Going! I decided to use zMAX in my 2002 Saturn SC2 DOHC. Well, I've driven that vehicle 325,000 normal miles. The engine has spent over 90% of its life running between 2,500 to 3,000 RPM. I've built my share of engines. I lost compression in one cylinder and diagnosed it as being valve related. I went on a search for a used head. While doing so, I noticed the typical accumulation of oil "crud" you see inside the valve cover. All the ones I looked at had about 90,000 miles on them. I purchased a nicely rebuilt head. While removing the head, I immediately noticed there was virtually no crud, just a film, and the cams had a goldish, burnished sheen to them I had never noticed before on such components. After removing the head, one exhaust valve was burnt, the source of the problem. I noticed it was very easy to remove the carbon from the tops of the pistons. This never happened before during the valve jobs I've done over the last 40 years. What really grabbed my attention was there was no wear whatsoever on the engine cylinders, none. I could not discern by touch even a hint of ring grooving at all. You could readily see the cross hatching from the factory cylinder hone. I replaced the entire timing chain set as it was at its wear limit due to stretch, the old cam and crank sprockets matched almost identically with the new ones showing very little wear at all. Simply amazing in my book. Based on past experience, I can safely attribute this to using zMAX. Who knows how long this engine will last but I'm going to see if I can find out. Many thanks and keep up the good work.

I've tried many oil 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 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!!!

This stuff works! Suburban-215K, GMC-310k, Camaro-185k, GMC-265k, Envoy-175k... over 1 million miles plus the hours on my equipment. I know zMAX works!
- T. Atkins
My Acura TL SH had been burning oil between oil changes, resulting in a rough engine. On the way home from a business trip I sat next to a car expert, who recommended zMAX. I added one bottle to the crankshaft and one bottle 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 it's brand new at 140k miles. Thank you zMAX!
- A. Patel
My Sante Fe just had the 100K mile checkup and still no valve adjustment. They said the inside of the engine still looks like it just came from the factory. Putting over 80 miles one way each day, I can say your product works! Keep up the good work.

zMAX stopped oil smoke from my old 89 Dodge Caravan and raised the idle to 200 rpm. This bottle is also going into my 87 Plymouth Voyager just to have it in the motor. Thanks!

My tranny has over 400,000kms on it and shifted very rough and took forever to shift. I added zMAX to the tranny. Within an hour of driving, it shifted like it did when it had 200,000kms on it. I hardly notice it shift anymore. Before it shook the whole truck really bad, now just beautiful. Maybe I'll get another 100,000kms or so out of it!! Highly recommended for any vehicle with any age to keep it running strong for years to come.

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 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 new step was to replace the pump at the huge price tag. I paid what I thought at the time was a lot of money for that little bottle of zMAX. I added it to my power steering. Started up the engine, turned the wheel back and forth 5-6 times and it got quieter with every turn. Drove the van around the block and by the time I returned, the noise had completely stopped and the steering was smoother and easier. I am a new fan and believer. That little bottle was worth every penny! Thank you!

Just want to say that I believe zMAX saved my motor. Over the weekend, I broke an oil line on my car and the motor went dry in less than 60 seconds. Had the car towed to my job and the car had less than 2oz of oil in it. Fixed the line, filled it back up with oil and it's perfectly fine. No metal in the oil. All oil pressures are normal even after the car is warmed up and I think the only reason is because I regularly use zMAX every 3-4 oil changes. It's unbelievable to me that none of the bearings were hurt. Just wanted to say THANKS A LOT and I'll be using zMAX on every vehicle I own.

I changed the oil and added a bottle of zMAX to the fuel and 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!

I decided to try your transmission product for my 124k GMC Sierra. My transmission was shifting very hard with noticeable clutch shuddering. Within 10 minutes of adding your product to my transmission, I started noticing a dramatic change in shifting smoothness. Amazing! I was so excited that I didn't have to spend money on a rebuilt transmission that I told all my friends at work about my success with your product. Thanks! Best money I've ever spent!

I bought zMAX Transmission Formula for my Lexus ES 300 2003. The 1st gear was slipping and creating a disgusting noise. My mechanic recommended I replace the transmission. I decided (at 195,000 kms) to add zMAX instead and 3 hours later no more noisy transmission! This product is awesome!

First car I owned was a 93 Accord nearing 200k miles. I used zMAX in the engine, trans and oil and after about 3k miles when the car was running, you couldn't even tell it was on from zero vibration. I've continued to use it in every vehicle, motorcycle, and outdoor equipment machinery I've owned since I was 18 and will continue for the remainder of my lifetime. No other additive comes close to the cleaning results I've seen firsthand of zMAX for the internal workings of the cylinder heads, valves, and fuel system itself!

My wife had our oil changed at one of those quick change centers. It was only less than a mile from our house. When she got back, I put zMAX in and we drove 40 miles to her mother's house. About half way back, the engine light came on. The car seemed to be running fine, so we continued. Total round trip 80 miles. When I got back, I checked the oil, only to find that the car had no oil. That's right, no oil on the dip stick. Bottom line - the engine shop never replaced the oil after removing it. And I can thank zMAX for saving my motor.
When I bought my 07 Shelby GT, old Carroll said I should use zMAX. I tried it once at 30,000 and was very impressed but decided I didn't need it for every oil change. At 45,000 I tried it again and am now convinced that it makes a tremendous difference in how the engine runs. The oil treatment alone is worth the cost and I will not change oil again without zMAX.

An additive that actually works and cheaper than an engine rebuild. Give zMAX a try and you will most likely be a customer for life. I know I am. My friend has an '88 Vulcan and was having operational issues so I recommended he add zMAX because of my good experiences with the product ('82 280ZX), '84 Camaro Z28, '72 Camaro, '97 Toyota Tacoma and more. It solved his rough running engine and really altered its performance for the best! One hot day he came over for a ride and I noticed a thin line of oil trailing him. His oil plug had dropped off and his crankcase was completely drained of oil but the engine was still running (albeit a little noisy). He had just gotten off the freeway. We immediately shut her down, got oil and a plug and refilled the crankcase. The engine smoothed out, became quiet again and all power was restored. I attribute the lack of engine seizure to zMAX because without it, I guarantee the engine would've completely seized without oil. He still has this bike 4 years later.

My use for zMAX is a bit out of the ordinary. I work in the AG industry as a custom applicator of chemicals and dry fertilizer. The machines I use for the commercial fertilizer applications are constantly in abrasive, acidic, and dusty conditions. With moisture added to the mix, the pins, bushings and pivot points of the machine's booms sometimes will not take grease. The unique zMAX formula works as an ideal penetrating oil to soften the hardened grease while giving the joints lubrication until they can be greased again. zMAX in an impact greaser is the ultimate problem solver for dry and/or rusty pivot points in these harsh conditions. The steel fittings on the hydraulic hoses of the same machine tend to rust quickly and seize so that is a hose needs to be replaced, many times they cannot be easily taken apart. A shot of zMAX on those connections at the beginning of the season penetrates and lubricates the threads so that repairs and replacements are much easier.

I have used zMAX in my cars for years. I was having trouble starting my lawn mower for a few months so I thought I'd see what zMAX would do for it. I put a few ounces in the oil and fuel and pulled the start handle. It started immediately. So now I put a few ounces in when I add fuel and oil and have had no problems starting my old lawn mower. It has started on one pull for over 1.5 years and counting.

I had filled up my bike from a couple of gas cans I had. Afterwards, the bike ran terrible... coughed, sputtered, lost power. I tried bottles of dry gas, gas treatment etc. in the tank. Didn't help. I found a bottle of zMAX in my garage and added it into the tank. I ran the bike for about 15 minutes and the problem started to clear up. No more coughing, sputtering, nothing. I have since treated the gas left in the tank with zMAX and I'm now back on the road. Thank you! You saved me a trip to the dealership to have them flush the tank and lots of service calls and dollars. zMAX is well worth the cost.

zMAX Bolt Lube was a blessing at Georgia Gun Training. We kept looking for a lube that would stay in place on the AR bolt carriers. All the other products gummed up or just disappeared. Bolt Lube is thick enough to stay in place. The zMAX component suspends the carbon and prevents it from sticking to the parts. The Bore Cleaner and Conditioner is the best ultra-penetrating oil, and breaks loose the carbon, copper and lead accumulations. - I. Chandler, GA
Michelle Chestnut, a long range rifle competitor, uses zMAX on her rifles to reduce the effects of copper and carbon fouling. Michelle is a two-time world champion in her age group.
Over many years, I have tried a wide variety of products to lubricate autoloaders with mixed results. I have found zMAX Bolt Lube to be a superior product for AR type actions especially when firing heavy fouling (surplus) ammunition.
- P. Dean
I have used zMAX Bolt Lube exclusively on my Savage 308 bolt gun with perfect results. The real test, however, has been my AR platform rifle in 300 BLK, often fired suppressed. This is a very dirty combination and Boltlube has not let me down. High heat, lots of crud, no problem. I will continue to use and recommend zMAX Bolt Lube.
- B. Barger
zMAX Bolt Lube will give an edge of confidence to any shooter that has durability in mind, even under the earth's most rigorous elements and surprises. Do yourself a favor and buy a bottle of this amazing product for your own peace of mind.

I've been an aircraft mechanic for 12 years. We used to rebuild piston engines. We used AVBLEND and it kept the cylinder walls so clean you couldn't believe it. Since zMAX is the same formula, I had to have it in my truck. It increased gas mileage, smoothed out all the rough ends in my tranny. And when I was four-wheeling, the power was right there. It's a phenomenal product!
As an aerobatic pilot, I need to stay in the air. During an air show over Lake Michigan, I blew an oil line, throwing oil all over the plane. The runway was about 8 minutes away. With complete oil loss, I was still able to get to the runway. I can only attribute this feat to having AVBLEND in my engine. Thanks to AVBLEND, I was able to stay out of Lake Michigan.
