Update: My 2004 TC now has 349,000 miles. At 288,000. It was using a qt of oil every 500 miles now it uses a qt at 4,000. This van has another 100,000 left easy! It runs great and is the best running cab in Myrtle Beach. Thank You Cerma!
Original: Just finished 4800 miles on the Cerma STM-3 Engine Treatment. Wow, my 298,000 mile cab was using a quart of oil every 900 miles. Now not a drop . It runs so quite, you can't hear it run !! I'm impressed! Also added the Cerma Transmission Treatment. As I service my transmissions every 35,000 miles, they are well maintained, but after the transmission treatment you sent, it is much smoother!! Wow!! I have a lot of cabbies asking me about the product. Thank you -- Wade

I will say I'm only 2 days into the treatment with 22k miles on the odo only 100 miles driven since treated and already noticing a big difference when driving it on the highway and even in the city. I must say I've been made a believer. The car feels more normal and definitely feels like it runs much smoother when really getting on the gas. As for the idling, starting to notice that it feels more 'confident' when idling now than it did before. Definitely money well spent. --- Sly4c

I've read this thread for a while and decided to buy some AT treatment and 2 engine treatments yesterday. But not for my Veloster. I bought a beater truck (165K miles) for hunting and use around the house so I'm going to treat that with CERMA because why not. I'm also putting an engine treatment into my moms car that just crossed the 300k mark. I've done homework on CERMA, listened to the discussions/arguments on here, and for me the "proof" will be the difference in these 2 vehicles after the treatments. Based on that I will decide whether or not to bother putting it in my VT. ))
So it's been a couple of months since I put engine treatment in my mom's (2001 Toyota Avalon) and my girlfriends car (2004 Toyota Corolla), I only told them I was doing something to their engine. After about a week my mom came to me and said that her hard shifting had disappeared and that it was smoother at idle. I drove her car myself at that point and sure enough, the quick/hard shifting had stopped. That was unexpected but good news. I noticed it had more pick-up on the highway when trying to pass but my mom doesn't drive like that so she probably never noticed. My girlfriends car has around 285K, after a month she mentioned that she could accelerate on the highway without having to floor it. I put the transmission treatment in my truck (it had a very delayed then hard shift into second plus i just bought it used) and immediately could feel that working. At first it ran worse, then over the course of half an hour in city driving it smoothed out considerably. The shifting in all gears is practically unnoticeable, though occasionally the delay into second shows up, but that is speed and acceleration based and largely improved from what it was.
All-in-all I feel more confident in this product and in the technology behind it. I will be adding treatments to my car in the near future. I felt the power gain in my girlfriends car but not as much in my mom's. However both idled smoother, and the shifting issue on my mom's was an unexpected bonus. This isn't some miracle treatment for adding horsepower but it does work. I could even smell some of the gunk in the engine burning off as I was driving the cars after first adding the treatment. I'll be adding it to my car, both the engine treatment and the turbo treatment, more for reliability and longevity reasons. If it can smooth things out on two cars that are at or over 300k then it can help my car reach that point.
The best. Powered up my 12 year old truck -- it feels like new. I have a Ford F250, 2003 with 200,000.00 miles and in good shape, but after I used this product I felt the change -- more power, quieter, faster to respond. I feel like I have a new truck. I also did the transmission, did not feel any changes but for prevention. However, the engine treatment -- wow, right away ...recommend it to all my friends. -- Giovanni via Amazon (Verified Purchase)

My fiat now runs like a 6cyl. Boy has it got power. It now beats lots of 6cyl. I did my engine using EVO oil and fuel treatment. -- Bill D.
Amazing!! This stuff really works as described and then some. I used it three 2015 GMCs (Denali 1500, Denali 2500, and Yukon XL). Smoothed out the idles , don't even know they were running, More responsive, and most importantly no lifter noise when you start them up first thing in the morning. Also increased oil pressure by 10psi. Amazing product!! Intend on putting in my fleet of dump trucks 15 liter Cummings ISX. -- Amazon Customer via Amazon (Verified Purchase)

Dear Great Cerma Product, I have just used the transmission and engine treatment. So Far So Good. I notice an improvement with the transmission, and the engine seems to be idling smother and faster. I expect to be most pleased with my investment on a 191K mile CHEVY Venture 3.4 van. -- Robert F.
