Chevy Camarom RS
I put it in the engine oil and transmission. Transmission stopped slipping on very first drive home from work. I could not believe it!
BMW 318i
Hi everyone!

This post is a "give back" I hope to help a few with this one, as so many helped me with replies on my first post. I learned much. At that time I was asking about re-powering or rebuilding the b43 Onan in my well maintained '83 BMW 318i. The reason was that it smoked FIERCELY, and overall sounded "loose." Despite those problems, it did still run with authority. Now I have resolved both those problems BEAUTIFULLY, almost without turning a bolt. My Onan hums smoother than any I have EVER heard.

OK, before I go any further, this is not a "spam" post. I bought the stuff I'll tell you about just like anybody else. I was reading on another forum about ceramic coating the insides of an engine, even old worn engines, how sweet they run after, and on and on. With that in mind, I went looking for the stuff they were talking about, an additive called cerma. Not being a big fan of additives, I paused and debated if I really wanted to spend $40 plus shipping on 2oz. of wonder goo. I also remembered a certain disappointing failure with Slick 50 or something like it in an Oldsmobile "a few years" back. Now, of course I suspect I am much like many of you. I wanted to hope against hope for easy & wonderful results. Besides, I knew I'd be tearing down the motor or replacing it anyway.

Guess what? I got BETTER than expected results! It worked. After 2-3 hours of running with this stuff, My Onan burns virtually NO OIL now. BUT, for the acid test, I did a compression test when it rained last week. I was originally pushing about 96# on the left and 100# on the right. Now I am pushing 125# on the left and 122# on the right. OK, sounds pretty good, but I wasn't off the hook yet. It still smoked really badly, even though it wasn't using oil anymore. After going through the most ridiculous long tear down known in mechanical history -- just to loosen the 2 carb bolts, I rebuilt the carburetor. Super simple carb to rebuild, stupid long to get off. I'm not even sure I really needed the rebuild, since the idle speed screw was open 7-1/2 turns when it only should be 1-1/4. Either way, I didn't want to have to pull that carb again so I rebuilt it anyway. That carb rebuild, 2 spark plugs, 1 set of points, and the cerma = the quietest, smoothest running Onan I've ever heard. Of course I expect to hear boo and hiss about cheating or using an additive, but it really has worked as advertised. Now if I can only fix my lights so they work, I've got a whole new 318. I will also be adding it to my hydro. hydro whine is a thing of the past with this stuff. Scary to add anything but Type F ATF, but judging from what it did for my old Onan, I'm going for it.

The trans was shifting so poorly I was driving in 3rd all the time. The dealer wanted $4000 for a trans rebuild. An INDEPENDENT shop put in their treatment with no luck! After 10 mins of putting in Cerma the car drove like new, maybe better!! The engine runs so smooth I tried to start it while it was running –oops! I’m a customer for life – THANK YOU!!!

Mitsubishi Challenger
Hullo John,
I bought 1 bottle of Cerma STM-3 Engine Treatment and 1 bottle of Cerma STM-3 Automatic Transmission Treatment from you in May 2008. I treated my Mitsubishi Challenger(see attachment) 4x4 engine which is a 3Ltr V6 in the engine and the transmission. I followed your recommended instructions for the run in, drained the oil out of the engine and refilled with new filter, and had the automatic transmission fluid completely replaced. This vehicle had done 260,000 kilometers and still had the original engine and transmission. It is now at 289K and had 3 further oil and filter changes, and I can tell you that the result has been nothing short of astounding. The engine was starting to smoke before I put the Cerma it in, This has disappeared completely. These engines are well known for lifter chatter. It has none of that. It is so quite, and vibration is so minimal, that my friends marvel at it when I tell them how many kilometers it has done. It has increased in power and responsiveness so much, that I have a hard time keeping my foot of the gas. I love it. This engine, sounds and performs as if it is brand new.

Ford Escape
We drive a 2005 Ford Escape that we leased new. The sticker for mileage said 19 city 22 hwy and we got an average of 20.5. We tried the cerma with stm3 over 2 years ago and have treated the engine oil 2 oz of STM-3™ metal treatment in the transmission 2 oz, STM-3™ in the differential 6 oz and the power steering 1 cap. We also have been using the STM-3™ MD at oil changes and have treated the gas with 1 oz approximately twice per year. Last summer in July we got 30 mpg and in November before the winter blend fuel we got 31. We have now tried the new STM-3™ Nano 1 oz in the oil, ½ oz in the transmission and 1 oz in the differential. We drove to Mason City checking our mileage and got 27 mpg on winter fuel. (last year on winter fuel we averaged 24 MPG) we then treated the fuel with STM-3™ Nano ½ oz, and drove the same road and miles home, checked it and with winter blend fuel we got 30.2 mpg. We can’t wait to see what it will be with summer fuel.

Follow up report:
We have used your products for over 2 years and can not believe the difference that it has made in our 2005 Ford Escape. We have gone from 20.5 mpg original mileage before treating with cerma and Nano to 32.15 mph on a return trip just last week (April 2008) The Escape runs so quiet that all we hear now is the tires on the road. No engine sounds. It shifts better runs smoother and overall performs better. Mike and Dea Shoars
Bagger Motorcycle
December 2007 - I treated my 2002 Harley Davidson Custom Bagger motorcycle on the trip to Arkansas. The main thing that I noticed is the fuel mileage increase of at least 6 mpg. I was very happy as I was driving hard at speeds of at least 75-80 mph all day long on a 1700 mile round trip. I have now treated my suburban and my Harley, and am going to treat my inboard motor before taking it to Canada on a fishing trip. I was a skeptic but I am a believer now.

November 2007 - I have treated my suburban with over 133,000 miles and can report that my mileage has increased from around 15 mph to 18.1 the last time that I checked it. I am pleased with the results that I have seen after adding the Cerma Engine Treatment.
Diesel Semi-Truck
Just a quick note to tell you what Cerma has done for my trucks.

We put Cerma in the whole system of one truck with 798,000 miles, (engine {470 Detroit}, transmission, and both rear axles). Within 50 miles 95% vibrations were gone, stack smoke was all but gone, and pulling first load with 68,000 lb payload, said truck walked off from a truck carrying same load that usually out performs treated truck. Also sealed oil leak on compressor head.

Second truck treated, has 1,500,000 plus miles, was basically parked in grass retired. Compression was low enough that either had to be used to start. Front bumper had 1.5 inch vibration both ways before treatment, and mirrors would have to be held to see clearly backing up. After treatment, truck will start without either, hence more compression, less than 1/16th inch bumper vibration both ways, and mirrors do not vibrate. Minimum stack smoke.

This Cerma product is awesome stuff!
