I own a 2002 Mack semi. My truck started using 2 to 3 gallons of oil per week. I was told I needed to rebuild the motor, rings, sleeves, rod, and main bearings. The motor had an excessive amount of blow by. I added Cerma and followed the instructions carefully. Over the next three days the truck used less than a half gallon of oil. Six months latter the truck has not used any oil between oil changes, and the blow by has almost disappeared. At my last oil change I pulled an oil sample. On a million mile motor the iron should have been between 50 and 120 parts per million. A new motor should be between 30 and 40 parts per million iron. My oil sample came back 20 parts per million iron and less than 5 ppm of other wear metals. The oil sample was taken at 18,000 miles on the oil and over a month of idol time. The numbers should have been elevated based on the miles and time on the oil. I have seen a ten percent in fuel economy in all of my trucks. This is the best product you can get for your truck or car!
Fuel Treatment from April 14th, 2015: Great stuff. My gas mileage definitely goes up steadily, as per my digital gauge, when I use this stuff. I absolutely love this product. My engine runs very smooth with this product. Highly recommended. -- MichiganSooner via Amazon
Transmission Treatment from Oct 26th, 2014: Had a rough (down) shifting Acura RL automatic transmission; other products helped but not past the short-term. This product worked like a charm. There is zero problem now. I could not be more pleased. -- MichiganSooner via Amazon

What the ......, this stuff actually works!
Here's the story...1990 Mitsubishi Montero that I bought new. First it was the unofficial Cheerleading Team vehicle for my daughter and now it is the unofficial Baseball Team vehicle for my son. Currently at 144,853 miles. I was turned on to CERMA by a gear head/mechanic friend of mine who swears by this product. Honestly didn't believe him, I actually tried it to sort of prove him wrong! Engine oil treatment first. When I added the treatment the engine ran smoother and quieter, literally within minutes.
Drove the Montero like that for around 2,500 miles then did an oil change. I did the oil change myself with the aforementioned gear head/mechanic. (By the way, the oil came out very dirty as a result of the treatment cleaning the engine). Added CERMA Motor Oil and noticed more power, and even smoother running than before.
NOW HERE IS THE KICKER.......my friend had the oil that we took out tested and the test showed that I have anti-freeze contaminating my motor oil. Supposedly if I don't replace head gaskets and or check the block for a crack and possibly have to replace (both costing about half of what the vehicle is worth) it would only be a matter of time before I cooked the engine. That terminal diagnosis was over 8,000 miles ago when I switched to the CERMA motor oil ......and I'm still running strong! -- Chris C.
I contacted the folks at CERMA and went over this with them and came to understand that the CERMA engine oil treatment and CERMA motor oil actually "TREAT THE METAL" of the moving parts as a form of lubrication as opposed to just being a lubrication between the metal parts.
Will post again when I hit 15,000 miles on the new oil!

CERMA IS THE REAL DEAL!!
I heard about Cerma oil treatment from a friend who had amazing results with a sluggish high-mile Acura minivan. I treated my Mercedes Benz '91 560 SEC (113k miles) 4 weeks ago with Cerma engine, transmission, power steering and fuel treatment and can report INCREDIBLE results. 1-click cold start ka-vroom EVERYTIME (as opposed to 4-6 turns to catch). The power seems unreal...squealing tires from a dead stop with 3/4 pedal - Even chirping tires into 2nd gear with pedal pined...on an automatic!! The transmission now shifts much smoother and the large shift bump typical of my gears is so much smoother. I have 350 miles since treatment and the car runs FANTASTIC. I had my 1st California smog test 2 weeks back and the technician was nervous I wouldn't pass beforehand saying these old cars with large V8s often have SMOG trouble. I guaranteed him it would pass knowing the difference in my vehicle since treatment. Car passed with flying colors, tech said "I guess you really know your car!"
I also treated my wife's '09 BMW X5 (55k miles) with engine and fuel products and it feels like a new car! VERY quick and snappy. When I added the treatment to her running engine the noise IMMEDIATELY quieted down so much that it actually startled me!!
I have told everybody about Cerma, and half my office has ordered it and a bunch of family members!
Thanks John for taking the time to explain the Cerma difference...Cerma is THE REAL DEAL!!
Going forward, ALL of my vehicles, boats. ATVs, and A/C units will be getting the Cerma treatment!!! The increased performance and efficiency combined with the reduced wear and tear make this the ideal product for me because I love to take care of my stuff, much of it vintage or collectible. -- Patrick M.

Just treated my 2007 Toyota Avalon with the Cerma Engine Treatment and the Cerma Transmission. Car is running smoooooth (the vibrating is down to almost zero)- thanks Cerma. The engine also had a slight miss when I accelerated. Already noticed a significant improvement and I'll let u know if it improves even further. -- Dave P. Kansas City, KS
Chief Doug   Carbide Chain Saws04/01/2015
I think we performed a pretty significant experiment with your product today. My training officer did not return to the office but I will get more information tomorrow. We took 2 identical roof cutting carbide chain saws and had the same operator on the same roof make cuts one after the other. Both saws were clean and one was treated with your Cerma grease product. My mechanic also attended and I got this information verbally from him, report and probably a video that I requested to follow. One saw treated with the grease and the other without. The temperatures of the chain varied from 185 deg F (treated chain) to 340 Deg F (untreated) and the saw did 6 cuts straight (treated) vs. curving toward the end of the cut for the non-treated. The stuff worked pretty well. This was all verbal and I will try to tighten up the numbers etc tomorrow. Also this was done with my East Haven FD personnel and New Haven Fire personnel together which is how we have been training on some houses that I had a connection on acquiring for them. In addition my training officer and also New Haven’s training officer are both Fire Engineering contributors and we did a national level video with them in the past so you may be able to get some large scale exposure from this. I will tie it up tomorrow and get it all straight from my Training Officer hopefully with a video. Chief Doug -- Douglas Jackson Sent: Wednesday, April 01, 2015 4:48 PM
Pdidheon  1990 560 SEC Benz03/23/2015
I never bother writing reviews, however, this product is FANTASTIC!! 560 SEC Benz with 113k miles, about 30k since valves...UNBELIEVABLE!! Cold start on 1st turn of starter EVERY time, not the 4-6 turns... After the results with oil treatment, did tranny, power steering and fuel treatments... Tires squealing out of stand still when pedal punched AND chirping again into 2nd gear...with an automatic. Strongly recommend to anybody who wants increases performance and efficiency and reduces emissions and wear and tear... I went for 1st ever Cali smog test...guy was shaking his head saying these older benzs with big motors are a problem...passed with flying colors. This is product is the real deal. -- Pdidheon via Amazon
Glen M.  2008 Ford Transit Diesel 2.4Ltr Turbo Van with 155,000km03/21/2015
Update from NZ on Cerma: Hello, December last year I purchased several products from you. I changed my oil ran the vehicle for a while the added Cerma. I make a regular trip up a rather steep and long hill, a 3km climb. When I purchased the diesel van it would pull up this hill at 100kph no issues with plenty of power to spare. I noticed late last year that it was not pulling as hard. I changed the fuel filter, the air mass sensors etc. Some improvement was gained but not back to what she use to be.
I added Cerma about 4000km ago. No immediate change in the hill pulling ability. However, last week she started pulling just like it use to. I have not made any modifications since adding Cerma. It will be due for an oil change soon - I have your oil here to change with. I am more than impressed with the product to date. -- Cheers, Glen
Zerocool  Montero Sport 1998 ES I4 2.4L01/05/2015
CERMA changed my old engine with 225,000 miles to a NEW engine with a power never seen. When I received the package, i opened it and i was suprised seeing the little bottle that i bought for 100 USD. When i am back to Haiti, i added the contains to my engine with 224,000 miles (Montero Sport 1998 ES I4 2.4L) immediately i feel my older engine is not the same, i got a new engine more powerful. my car is going to develop a power never seen since i bought it from Atlanta USA. This product is simply the best in this category. By Zerocool on Jan 05, 2015 via Amazon
