More responsive
“Recently I got Cleanpower and FTC Decarbonizer and started using them immediately in my Nissan Frontier gas V8. Within just a few days I could feel an improvement – it was just running better, it was more responsive and I could certainly feel the power was up from where it used to be. I expect it will improve more even yet as things get cleaned. I’ll use the Flushing Oil Concentrate soon and let you know the results.
Update – 1 week later – I swear IT IS making a HUGE difference! (Cleanpower and FTC Decarbonizer) Acceleration is so much better, smoother and more responsive. It’s a different vehicle now!! I cannot remember when it last was like this!”
Jeremy N, Logan, UT
Great results every time!
“Over time I’ve been very happy with the results I’ve gotten from FTC Decarbonizer and Cleanpower in my Silverado and my little old snow blower. When I took our boat on the lake this summer it was running pretty bad (Volvo Penta gasoline engine). It had trouble holding high RPM, and was idling terrible. As I didn’t have either of the products with me, I just put up with it all weekend. The next weekend though I put the products in the fuel, and as expected, within a short time everything improved dramatically. The previous problems disappeared, the engine was performing as good as ever, if not better. I’m always impressed by these products, great results every time!”
George B, Springville, UT
Even better
“Having seen the great results I got from using the FTC Decarbonizer and Cleanpower with our old Mazda 6 recently, I got the Flushing Oil Concentrate and AW10 Antiwear from you to use when I did the oil change yesterday. The flush worked great, the oil that came out with the flush was very dark (new oil only 45 minutes earlier). After doing the flush and then adding the AW10 Antiwear to the new, good oil, I could immediately tell it idled much smoother and was much quieter. It has had a slight chain rattle for a while now. I can’t hear the noise at all now, it’s very smooth and quiet now. Again, thanks for these great products, they work!”
Mike C, Springville, UT
Mazda 6 Emissions problem
“Our old 2006 Mazda 6, with 167,000 miles has been running terrible for months! Local shop told me it was bad injectors. I can’t think how many injector cleaner products I bought from the local auto parts store – tried them all, nothing changed. In fact, it only got worse over time. Emissions Check was due, I knew there was NO WAY it would pass. I called you guys and you said get some Cleanpower and FTC Decarbonizer in the gas tank, then take it for a drive. What a difference! Within 30 miles it was running better than it has in 10 years! So much smoother, crisper, and I think it’s quieter too. It’s nice to drive the car again. I took it to Emissions and it flew through. I’m really grateful for your help, these products really work! Amazing.”
Mike C, Springville, UT
What a difference!
“I’ve been using FTC Decarbonizer and Cleanpower in my Silverado for a long time, and am really happy with the results. After the first snowfall this winter I decided to put a little of both products in my little (gas-engined) snow blower. What a difference it made! Immediately it seemed to have more power than before, it tore through the snow so much more easily – it would hardly bog down whereas before it struggled with any more than a few inches of snow. It just seemed to pick up power, easily blowing a good 6 inches of snow! And the other thing is that it now starts first pull of the cord, every time. Before this, it usually took a good 5 or 6 pulls to fire it up. So much better!”
George B, Springville, UT
Great products!
“I recently sold my truck, but for the time I had it I ran the fuel additives in it. Great products!” (FTC Decarbonizer & Cleanpower)
Mike S, Hillsboro, OR
Small gas-engined compressor
“I had a little FTC Decarbonizer and Cleanpower left over so I just put them both into my gas-engined compressor 5hp gas tank. I know I added too much, as the tank is only 1/2 gallon, and I put in more than suggested, so it was super concentrated. Of course, it ran like crap and a bunch of smoke came out, but not blue smoke, just black smoke. When I held a white shop rag in front of the exhaust, it was filled with chunks of soot and what looked like carbon. Could it possibly work that fast?
I just left it running, lopping along and surging, but when I came back in about 10 minutes, it was running strong and no black smoke. It was running so well, I’m thinking Can this be right? It’s filling up the 100PSI tank way better than before. It’s really just crazy that my little air compressor that would darken a white rag now has completely no smoke coming out the exhaust, how can this be? I’m literally looking all around for an exhaust leak or checking if all the oil drained out. WOW!”
Chris F, Lynnfield, MA
Preventative maintenance, great results
“I started using the products about 6 years ago when I needed to rejuvenate a Yanmar turbo 4-cylinder engine on a newly purchase 27 year old sailboat. The engine was in very poor condition – the exhaust smoke was black, and it had little torque. As it’s a marine engine with little chance of working “hard”, it did take quite a while of using the FTC Decarbonizer and Cleanpower, along with 3 oil flushes over time using Flushing Oil Concentrate to get the engine back to as new condition. As you know, the turbo was mechanically damaged, so I replaced it.
Seeing the wonders these product can provide I started using them on my two V6 Mercedes diesel-engined vehicles. These are late model vehicles with diesel particulate filters and exhaust fuel treatment additive (DEF).
I bought both of these vehicles, used, with low kilometers. I now have 110,000 kilometers on one car, and the SUV has reached 160,000 kilometers. Both engines run with FTC Decarbonizer and ULS Diesel Enhancer. When I change the oil, I use the Flushing Oil Concentrate as you recommend. I always use high quality full synthetic oil in these engines.
I can see that the engine oil is soot/carbon free, and the oil remains clean and honey colored for a period of time.
Result is my cars perform superbly with unbelievable acceleration (for a diesel) and are very economical on fuel.
So for me these products are preventive maintenance and I know it is not a scam with the results I get.”
