”I’ve built over 100 different kinds of cars… Shelby Cobra, over 20,000 Shelby Mustang, the Viper…at 77, I wanted to see if I could build another good automobile like the Cobra. I call the car the Series One. We’re putting zMAX in each and every one that leave the factory. It penetrates the metal, decreases the friction, cleans the carbon residue out of the engine. Therefore it gives you a more efficient engine and a lot more durability. I’ve got my reputation to protect and I wouldn’t recommend zMAX unless I knew it worked.”

325,000 Miles and Still Going!
I have a 2002 Saturn SC2 DOHC that I purchased brand new. As I intended to drive this vehicle until it died, I decided to use zMAX as it simply made sense to me. Well, I've driven that vehicle 325,000 normal miles. That's well over once around the world each year. The engine has spent over 90% of its life running between 2,500 to 3,000 RPM. Not loafing along by any means. While not a professional mechanic, I've always repaired my own vehicles and having once been a motorhead, I've built my share of engines. I lost compression in one cylinder and diagnosed it as being valve related. Not having a lot of time for the vehicle to be down, 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 from a motor head once planning to do a turbo project. While removing the head, I immediately noticed their was virtualy 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 very easy to remove the carbon from the tops of the pistons simply by using a putty knife after a little soaking in carb cleaner. This never happened before and I've done plenty of valve jobs 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 indentically 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 your product. I've never endorsed anything before and have hi-resolution photo's of the cylinders to back it up. 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.

Michelle Chestnut, a 17 year-old long range rifle competitor, uses ZMAX lubricant on her rifles to reduce the effects of copper and carbon fouling. Michelle competes in sanctioned matches with 50 bmg rifles at a range of 1000 yards. She is a two-time world champion in her age group . She and her ZMAX lubricated rifle achieved her highest score of any class at the world championship.
Thanks so much for helping me out with my order via phone this morning. You made spending money with zMAX an enjoyable and un-scary experience on this Friday the 13th.
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, and with moisture added to that 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 machines tend to rust quickly and seize so that if 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 when they are needed.
It is my pleasure to whole-heartedly endorse such a fine and proven product. And it gets even better: zMax is made in the U.S.A.!

Let me start off by saying that I have never really believed in products that claim to improve the workings of my vehicles engine. In the past I have used products like Slick 50, Restore, and other such products. Unfortunately I really never had any luck with them - That is until now. I started off by trying to use zMAX in my 2007 Chevy HHR. I guess it was to new of a vehicle, because I never saw any change that I noticed. Recently, I started using zMAX in my old 1993 Toyota Pickup. When I inherited the truck I was getting around 14 miles per gallon. The first thing I did was do a tune up on it - changed the plugs, plug wires, distributor cap, and rotor (that was around 106,000 miles). That helped boost my Mpg up to around 18 miles per gallon. Then at around 109,000 miles I decided to try your product. To my amazement my Mpg went up to around 20 miles per gallon. I recently did an oil change at 112,000 miles and added zMAX again. I now have a little over 114,000 miles on my truck and I am getting, on average, around 23 miles per gallon. I think that adding zMAX to that old truck was the best thing I could have done to it. I plan on using zMAX with every oil change from here on out - until the engine stops running or the body rust off. With it being a Toyota R22 engine - I believe the body will give out first.

My name is Bob. I'm from Apache Junction, AZ. I own a 2006, Scion xB and have used your product since purchasing the car brand new...changing the oil every 5000 miles (Valvoline 10w-30) and always adding your oil and fuel treatment with every change.
I've put on 122,000 miles in the 5 years I've owned my car and have had zero mechanical issues. Actually, the only part I've had to replace is the dipstick tube O-ring (other than routine maintenance). I commute 70 miles each day to and from work (the little guy has been cross country several times as well). As you know, Arizona has some pretty harsh summers where day time highs exceed 110 degrees F quite regularly. To this day, I don't burn a drop of oil and he still runs like a scalded dog. I did some performance bolt on upgrades around 60,000 miles...headers, performance exhaust, cold air intake, and a Greddy supercharger just to give me a little more get up and go and I believe that your product continues to provide the extra protection I need to get many more trouble free miles out of my little car.

I use your product religiously and would like to display my appreciation. From the first time I used your oil/fuel additives, I immediately felt the change in both fuel consumption & oil treatment. Immediately after using, my Jeep felt as if I had a 40 mph tail wind behind me! Idle was smooth, mpg were extended. I'm on my 5th treatment and tell friends what a difference zMAX makes.

Hello, I just want to give you all a great big THANK YOU, I have been a zMAX user since around 1997?. I first saw a TV infomercial, so I ordered. It was funny actually. I received the engine oil and fuel additives, and also small bottle for small engine oil, I put bottle of additive in my small air compressor, the next morning I found a puddle of oil under compressor, but the engine oil is still inside of engine, I found the drain plug was just loose enough to let fine zMAX out, but tight enough to keep engine oil in.
That was when I was a true believer in your product, I have been using zMAX in every vehicle I have owned since then. And My nephew has grown up with me has been using zMAX in his vehicles since he started driving.
I received a check from you back in 99 or 2000, from a lawsuit, I do not know what it was about. But I took the money, and spent it on zMAX for my vehicle at that time, and just what you to know, I am still a user of zMAX.
Thank You, I am so happy to see your product name on SPEED channel on Monsterjam and on Passtime, I sure am glad to see you support such programs.

When I bought my 2007 Shelby GT, Old Carrol said I should use zMAX. I tried it once @ 30,000 & was very impressed but decided I did not need it for every oil change. I didn't use it again until 45000, but now I'm absolutely convinced that it makes a tremendous difference in how the engine runs. The oil treatment alone is worth the cost & I will not change oil again w/o zMAX. The smoothness and response is amazing. It's as good as advertised and more. I can tell the difference immediately.

I am a retired aviator. I have used your product religiously from the time of my military career began and to this day. I had a 99 Jeep Cherokee and I was fishing in Freeport TX about 60 miles from my home. I ran over a piece if angle iron and ripped a 7.5 inch gash in my oil pan. It was about 3:00 am and I decided to try to get as far as I could before calling a tow truck. I never made the call and made it home. Had I not been running your product the motor would have seized within minutes. It makes me laugh when I see the dura-lube and Slick 50 ads running a water hose over an open engine and claiming it is the product. I race cars and tried to get the guy putting on a show at the track one day to stop the water and see how long it would run and was asked to leave. Your product works and has gotten me home in more than my Jeep for what it's worth.

Just a quick note, telling you that your product is amazing!!! I have an '01 Mustang, and I noticed a difference almost right away, once I started using zMAX. I use it regularity, in my oil and fuel. I stand behind your product, recommending it to any other members of the Canadian Military I see. Just to let you know, our mechanics are using it in our vehicles overseas in Afghanistan, where I was for the last 6 months. We all seem to agree. It works!!!

I'm the original owner of a 1996 Trans Am WS6 Harley Davidson Edition, with 27,000 miles. I've been keeping track of my gas mileage from "Day One". I purchased the car with 102 miles on the odometer from a Pontiac dealer in Culver City, CA. I've used it sparingly for around town and to and from work driving. Most of the miles are from "Road Trips" to Las Vegas, Laughlin, NV and Bend, OR. And now, since retiring to southern Alabama, a few trips to the Chicago area. Now you have the background of the car's road usage.
When I purchased the car I changed the air filter to a K&N and installed a B&M Ripper shifter, with a shorter throw. I've also used Mobile 1 from about 6,000 miles. At first I got 9-10 MPG in town, you know "Los Angeles traffic sucks", and on the first trips we got between 19 & 23 MPG. As the mileage on the car increased, of course so did the gas mileage, and the best ever was 26.25 MPG after the addition of the K&N filter.
This year, May 2009, I went to the Chicago area to visit my children and grandchildren. Before the trip I had the oil changed, and after seeing a zMax commercial I thought I'd give it a try. I bought it at my local "Advanced Auto Parts" store. With some city and some highway driving on the first tank of gas I got 26.01 MPG, a bit of a surprise, as I figured it would be closer to 20 to 22 MPG. The next tank after 333.5 miles and some stop and go due to road construction was 26.68 MPG. Then to my amazement at 357 miles 29.26 MPG. WOW !! A performance Automobile and this kind of mileage!! With the traffic and construction in and around the Chicago area my next tank was only 20.5 MPG with 280.2 Miles on that tank of gas. As the return trip to Alabama progressed and another 395 miles I got 28.21 MPG. My last tank on the road was an even bigger surprise at 29.56 MPG.
I've been a professional Mechanic for over 40 years and have used other oil additives, but none with the same kind of results as zMAX, this is great stuff! I DO BELIEVE IN zMAX!! We'll be using it in all of our vehicles in the future!

I used it on my mustang with 50K miles and before I used it I noticed that my valve train had a yellowish tint on the metal surfaces and after a did a zMAX it cleaned everything up and made it look so shiny and new I was amazed. I will be using it in all my 4 vehicles every 6K miles.

Three years ago I bought a used 2003 Mitt.Lancer ES with just under 60k on it. I was averaging around 25-26 mpg. I have done/bought a few things to the car (K&N air filter, E3 spark plugs, and changed to Royal Purple oil) and all of these combined has increased my horsepower and mpg. The first time that I used your product-WOW! I noticed a difference in the horsepower/pickup of my car. Without the zMAX (and having done the above) I went to 30 mpg, but ever since using zMAX, I am now averaging just under 35 mpg!!. The car just recently turned 100k and is so smooth. In the past, I had tried those so called oil treatments (slick50,Duralube) and they did nothing like what zMAX has done. I will continue to use your product and I am always recommending it to my friends/relatives. Keep up the good work.

The company I work for purchased a 1995 Ford Ranger pick-up several years ago with 84,000 miles on it. I use synthetic oil and service it every 5-to-6,000 miles and add zMAX engine and fuel treatment every oil change. As of this date the truck has 300,400 miles on the odometer. What more proof do you need than this mileage success I've had with my truck by using zMAX.

Hi , my name is R. Holland. I have a 493 stroked big block Mopar with a F1 ProCharger 1100 HP. I have 7 broken pistons due to poor design, valve notch too close to ring land. I use zMAX and believe it or not the pistons walls look great. It's going to cost me $1700 to get this back together, but that is better than $5000 had I not used zMAX.

Recently, I bought a Nissan 93 Pickup with 38,000 miles. After the initial driving period of 5 days, the valve started to knock. The knock was so loud that I thought I bought a diesel! I had a neighbor listen to my engine and he said, ” Do an oil change and go buy zMAX! I was disbelieving because I have never been a big believer in those types of products. I have been very religious with my other vehicles. Changing oil every 3,000 miles. One car went 320,000, the other 280,000, and my current one is 74,000 with no problems.
I changed the oil in my truck and added zMAX. I took the car for a drive for 20 minutes, returned home, and still had the knock. I was thinking that I wasted money again on another miracle product. So I went to bed. I drove the truck to work the next day thinking about the upcoming valve job I would be paying for. Then, about half way to work, my noise stopped. I was amazed! I pulled over, revved the engine and no noise! It has been 3 days later and no noise. I am very impressed and have also noticed a big difference with the performance of my truck! With this increased performance, it feels like a brand new engine!
Thank you, for making this product available to the common folk! I love this product and I will keep using it! I have referred 5 people and after reading the web site, I will be referring everyone I come in contact with. I am very excited to go buy another package to use with my other vehicle.
Thank you,

We own a 1990 Nissan Pathfinder with 166,000 miles and a 1988 Ford F-150 Pickup with 153,000 miles. I began using zMAX about 6,000 miles ago on both vehicles and I must say the results were dramatic. The Pathfinder went immediately to 22.5 mpg and the truck is up to almost 14 mpg.
The most amazing thing though is the increase in power that was also almost immediate. We live in the Sierra Nevada Mountains in California and the uphill driving power improvement is the most noticeable. To get to our home from the Central Valley of California is a long uphill climb, and the Pathfinder now makes the grade without downshifting to 2nd at all. This has not happened in years! Both vehicles run like they had 15,000 miles on them, not over 150,000. I can only imagine the fuel savings this country would enjoy if every car in our category used your product. I recommend it to everyone I know. Thank you from a VERY satisfied customer.

“I’ve been an aircraft mechanic for 12 years. We used to rebuild piston engines. We used this product called AVBLEND with LinKite and it kept the cylinder walls so clean you couldn’t believe it When I found out the zMAX had the LinKite formula in it, I had to have it. I put it in my truck. It increased my 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.”

I have been using your product on my 2001 PT Cruiser for the last 8½ years. I bought this car new in 2000. Every 6000 miles I use the engine additive and the fuel additive as directed. This morning I just broke 268,000 miles. Clearly this product works. I was raised believing that if you take care of your body it will take care of you. With zMAX its easy to take care of your car so it takes care of you.

I have a 1992 Jeep Wrangler that I use for off roading and around town driving. I saw a TV commercial about zMAX and was a little skeptical, but since my Jeep has over 250,000 miles on her, I figured I would give zMAX a shot. I went down to the local auto store today and bought the zMAX treatments for the fuel system and the engine. I put them both in while still in the parking lot.....I noticed almost an immediate difference at idle, and it was driving much smoother within 10 miles or so. I can't believe the stuff really work!

I wanted to let you know about my use of your product. I had filled up a couple of gas cans in order to fill my motorcycle. On putting gas into it one day, the bike ran terrible... coughed, sputtered, lost power. I was afraid to take it out on the roads for fear or it dying on me while being on a highway. I tried bottles and bottles of dry gas, gas treatment, etc. in the tank. It seems to help a bit, and then went right back to the way it was. I was out in the garage and found a bottle of zMAX that I had in the cupboard and figured it wouldn’t hurt to put that in. I ran the bike in the garage for about 15 minutes and the problem started to clear right up. No more coughing, sputtering, nothing. I have since treated the gas left in the tank with zMAX and I'm now taking the bike back out on the highway. I just wanted to tell you how great your product works. I have told everyone I know about the bad gas I received and not to go to that station and get watered down gas. I am now telling everyone I know that zMAX cleared up my problem and am highly recommending it to all.
Thank you, you saved me a trip to my dealership to have them flush the tank and lots of service calls and dollars. zMAX is well worth the cost.

Just wanted to tell you how much I love your product. I have a 2009 Toyota Yaris with 14,000 miles on it. I have used your products for so many years in other vehicles I have owned and I must say your product is truly amazing. My Yaris has gone from 39 mpg on hwy to almost 45 mpg with your product.
Wishing everyone at your fine company nothing but the best and god bless to all. Your product leaves me speechless and I am so glad to start using it again in my Toyota for the rest of its life. #1 fan here in NM

My online purchase was seamless and I received my order promptly. I ordered 4 quarts of ZMAX at the holiday special pricing. Thank you! I signed up for emails and look forward to receiving them.
I'd like to say that anyone who doubts the efficacy of zMAX need only try it. Case in point: I have a 1981 242 GLT Turbo Volvo, the first turbo Volvo ever made. I bought it brand new off the showroom floor 29 years ago. I recently got it back from the last of my three sons who all drove it during college. Needless to say it was trashed from neglect but it still ran. After refurbishing and servicing the car thoroughly, I changed the oil and added zMAX.
When I changed the oil at 3000 miles it was completely black. I then added zMAX at this second oil change and I can now barely see through the oil on the stick at 3K. The blow-by is gone and the engine is running nice and smooth, hence the 4 quart bottles sitting on the shelf ready for the my service interval, which by-the way, will be extended since the oil is so clean. My engine has 248K and the way it runs is simply spectacular. The valves are the same as when they were first adjusted at 12K. Volvo built this engine especially for the introduction of the Turbo and pulled out the stops in machining. zMAX brought it back to factory cleanliness and it is supersmooth now. The fuel system with ZMAX corrected the sticky mechanical injectors and it simply purrs for lack of another word.
Lastly, I have read many disparaging remarks about zMAX and the endorsement by Carroll Shelby. I'll simply say: I have never seen Shelby endorse anything. (If I missed a product, I may have been out of the country). zMAX is an old school proven formula that works. I trust the man and my experience with the product backs that up. Micro-lubrication has demonstrated itself to me to mean.
A thorough cleansing of the engine, especially the rings, replacing it with lubrication that lays the foundation for engine oil to perform its task.
Again, my engine has never run this smoothly in years. Thank you for listening, great product!

I have been a user of zMAX for at least 18 years and didn’t realize really how great the product was till a couple of years ago when I went to change the oil in my old push mower. I turned it upside down and to my surprise there was NO oil in it!! Now I had always used zMAX in the gas and crank case (about 7 years on this mower), so I wasn’t too worried. I went ahead and put oil in the mower, started it up and it smoked and fouled up the spark plug…guess I had a gasket go bad or something…well I poured all the oil back out and cleaned the plug before starting it again…it started right up and ran great…again, with NO oil in it…only the years of using zMAX. It’s been a couple years now and the mower is still going strong with no oil. I had to change out the pull start string the other day, and in doing so I looked into the crank case…and yes…bone dry of any oil….
AMAZING…..

I recently put the zMAX treatment in my van. The van has a 6.0 litre gas engine the unit is 3500 long wheelbase. I travel approx 6500 kms per month. I travel the province of BC with all the long hills, I carry heavy weights with this unit to max gvw.Since putting your product in I gained approx 35-40 extra kms per tank, the engine performance is excellent. When passing a b-train semi loaded up with my products the van performs like its half empty. I thought this was BS but MR SHELBY recommended it that was good enough for me. WELL HE WAS RIGHT.
Keep up the good work, Love your products

Testing Experts
zMAX scientific testing summaries were produced by petrochemical and oil industry experts Maurice LePera and Gerald Keller. Additional input was provided by Oil-Chem Research Corporation’s Ed Rachanski, Sr., James Klepal, and Bob Ziomek.
The tests conducted on zMAX are based on the accepted protocols as directed by the Society of Automotive Engineers (SAE) and the American Society of Testing and Materials (ASTM). zMAX requires a “soak in” period in order to achieve maximum benefit, therefore, when necessary, the protocols have been modified only to include a “soak in” period for zMAX. The results of these tests show that zMAX soaks into metal; reduces friction; increases horsepower; dissipates engine heat; helps improve or restore gas mileage and reduce emissions in older cars, by virtue of reducing engine deposits; helps maintain gas mileage and emissions in newer cars, by virtue of reducing engine deposits; helps reduce engine wear on vital engine parts, by virtue of reducing engine deposits; and helps to extend engine life, by virtue of reducing engine deposits.
