What our  customers are saying…

“I did the engine flush today, the oil I put in for it came out as black as the old oil. Before, it was running down the road at 35-40 psi, idling at 25-30 psi oil pressure. Now since the flush and a new brand of oil, it runs down the road at 45-50 psi and idles about 40-45 psi, still has some blow-by but it will really tell when I put load behind it tomorrow morning. Can’t complain for a 950,000 mile 19 year old engine. It’s a 2000 W900L 12.7 Detroit, right around 954,000 miles on original engine. I can tell that it knocked the blow by down, I’m pretty impressed at what the (Flushing Oil) Concentrate can do, still ran at those psi’s loaded.”

Shively LLC, OH

“I’ve been using the FTC Decarbonizer in my Freightliner N14 for a few months now. As you know I was a little wary about trying it, but the information you gave me convinced me to give it a shot. It’s made a tremendous improvement! Blow-by has decreased from 6 inches down to 1inch, exhaust smoke has died down considerably, fuel mileage has gone from 5MPG to close to 6MPG (20% increase), the engine stutter between gear changes has disappeared completely, the high temperature problem it had at idle is totally fixed, the engine starts so much better now than before, the engine is running so much smoother and better – it’s doing everything it’s supposed to! I did the engine oil flush with Flushing Oil Concentrate over this past weekend. Seriously, I was amazed at the huge amount of sludge and carbon that came out, all in just one stroke! I’ve driven for a few days now, and checked the dipstick – it looks BRAND NEW, it’s cleaner than ever! The cheap products I’ve tried before did absolutely nothing. Your products have done exactly what you said they would. Truckers Blow-by Pack, hell of a product! I strongly recommend it to anyone. It’s worth every cent.”

Howard B, Toledo, OH

“I did the oil flush with great results as far as noticeable sludge. While not 100% free of sludge (oil now has slight dark grey tinge, but does not stain fingers when rubbing together), but the difference before and after is really striking, great product! The performance and lowering amount of smoke at start up are noticeable & engine seems quieter.
Other than sludgy oil, my main concern was a bit of blue haze I’m getting driving up grades when the engine is under load. I believe I am burning a bit of oil, not noticeable on the dipstick level or anything, but that blue haze is a tell-tale sign. After the flush, the blue haze was only just noticeable, but I think it may be as I drive more, it’s possibly improving (Cleanpower working?) I am not even half way through my first tank of Cleanpower, as I haven’t been driving tons.
Yes I do want the FTC Decarbonizer!”

 Christian K, Oakland, CA

“I want to thank you for putting out a product I can truly say has saved me money. I repair and sell Grasshopper Lawn mowers and love their Kubota Diesels and have had a few of them that have not been taken care of, but instead of having to tear them down and rebuild them, I added the FTC Decarbonizer and the Flushing Oil Concentrate, and was blown away with the results of my first application, before I put the additives in the one mower I truly thought I was going to have to take apart. I ran it for a month and during that time, I noticed less and less blow-by and it had the power to cut thick thatch with no problem. I just wanted to let you know what good products you have.”

Rich M, Swansea, IL

“The products (Flushing Oil Concentrate & FTC Decarbonizer) worked great, really exceeded my expectations. Hopefully the longer they run, the better they will get. I just placed another order today for one of my hotshot drivers. Thanks for everything.”

David L, Tyler, TX

“I run a 2012 Kenworth W900, with around 340,000 miles on it. My buddies lately have been getting hit with massive repair bills on their trucks – it has crippled some of them. They’ve been telling me I’m gonna be next as my truck is at the mileage when things start to go bad. I do not want to be in that situation. I believe it’s better to spend affordable dollars now on preventative maintenance, than unaffordable dollars later as a result of major component failure. So I’m using the Truckers Blowby Pack – FTC Decarbonizer and Flushing Oil Concentrate.”

Dusty R, AZ

“200,000 miles on the build, this engine puts out 650 hp and 1650 lb/ft of torque, the dipstick is after one treatment of your Flushing Oil (Concentrate) treatment product. I thought I was rolling the dice when I got your products and would never have believed this. There it is right there, in the picture, the dipstick after it was run up and warmed and driven for about 10 miles. Can’t wait to see what the rest of the product FTC Decarbonizer will do for my truck as well as the fleet of equipment that I take care of. I’m sure we will be a customer for many years to come. I manage a fleet of equipment here in Colorado. I took the dipstick down and showed it to the owner because, well, you just have to see it to believe it.”

Phil P, CO

“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 CRD Fuel 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.”

Jacques L, Quebec, Canada

“Our old, yet mostly reliable 1997 Astro van has had a progressively worsening
low oil pressure problem for a long time. At idle, oil pressure sat around 30psi, and at higher RPM, it could only manage just over 40psi. Highly recommended by a friend, I did the engine flush with Flushing Oil Concentrate. The very first start with new oil, and immediately the oil pressure at idle was 55psi. At highway RPM it now sits solidly on 60psi. I couldn’t be happier with the result! Awesome product, awesome result. Thanks.”

Nathan A, San Francisco, CA

“My Series 60 Detroit developed an oil use and blowby problem at 500,000kms (310,000 miles) after an in-chassis rebuild. Running your Flushing Oil Concentrate (in combination with FTC Decarbonizer) tightened up the blowby and oil burning. I’ve continued to use these products and 6-7 years later, the truck is still going great.”

Phil Riseley, Riseley’s Bulk Haulage, Australia

“Tell ya what! After using the Flushing Oil Concentrate the way you recommended, the engine oil is still as clean as new after about 600 miles! I’ve noticed too that the engine seems to be smoother and up on power – probably the FTC Decarbonizer doing it’s thing! (2012 Cummins ISX). I’ll keep in touch.”

Marvin M, Lewistown, IL

“Just thought I’d send you a picture of the dipstick approximately 700 miles after we did the engine
oil flush with the Flushing Oil Concentrate. The oil is  still so clean I can hardly see it on the dipstick. I am still amazed at how well it cleaned out the sludge and other muck in my 2010 Chevrolet Cruze Diesel. I’d never thought diesel oil could be so clean. Amazing result. Many thanks.”

Brian M, Logan, UT

“My 2008 Chevrolet Duramax, with only 129,000 miles, was running badly and intermittently blowing clouds of black smoke at highway speeds. It had bad power loss above 65 mph – usually no throttle response above this speed. Also, it felt and sounded like the turbo was constantly surging at any speed. Over the last couple months I’ve been using FTC Decarbonizer and CRD Fuel Enhancer in the diesel fuel, and it has made a tremendous difference! No black smoke! Running so much smoother, full power again, and I’m getting 2.5 mpg better fuel mileage! I’m looking forward to the results I get from the Flushing Oil Concentrate. Great products that do as you said they would. Really appreciate your help.”

Ryan D, Lawrenceburg, TN

“Just a note to say the truck (5.9 Cummins) is running much better and smoother. The oil is still normal and clean after 600-plus miles, oil consumption is much lower now as well, and fuel eco is up. The Blow-by Pack has worked as you said it would. Thanks!”

Marc M, Chico, CA

“I used the Flushing Oil Concentrate in my 1997 Dodge Ram Cummins. Amazing result! The oil on the
dipstick stayed really clean – never seen that before. And it runs a lot cooler now, especially when towing the 5th wheel. Many thanks!”

 Dana Z, Santaquin, UT

Thought I’d let you know how the FTC Decarbonizer worked with the Freightliner. It has 2 million miles and never had a rebuild, but starting to have blowby. I added the FTC Decarbonizer that you sent me, and am amazed at how it worked. The blowby came to a screeching halt, fuel mileage went from 5.4 to almost 7, and within the first 100 miles it was running a lot smoother, and could really feel more power. It really blew me away. My driver loves it! I’ll be telling my buddies about it, for sure! Send me some more, and add some Flushing Oil Concentrate to my order as well. Very impressed.

Bill P, Sharon Springs, NY

I had a drastic blow by problem with my tractor and was using 2-3 quarts of oil per week without driving it more than 1 hr per day.  I talked to 3 different mechanics and they all said that an overhaul was the only solution and it would cost at least $5000. After talking to Pro Maintenance Additives I felt assured that it was worth a shot to try out the FTC Decarbonizer and the Flushing Oil Concentrate. I did and was amazed at how fast it worked! I did the oil flush as recommended and also put the Decarbonizer in the fuel tank. I drove it the same as before and I didn’t need to add any oil for the first 3 weeks, then I added 1/2 quart.  I went another 3 weeks and added another 1/2 quart…  the blow by virtually stopped from then on, I’ve only added a little oil now and again when I remember to check it.  I started the process in January and it is now the end of May and I have added approximately 3 quarts total in 5 months and don’t expect to have to add much at all as long as I keep using the Decarbonizer each time I add fuel. This is amazing to me!  I didn’t expect it to be such a drastic change. This is saving me $5000 plus the downtime it would have taken to overhaul the motor.  I own a horse arena and I need to groom it every day so to be without it for 2-3 weeks was a nightmare for me.  That’s why I started looking for another solution.  I’m sold!

Bruce W, Carthage, MO

Hello Jimmy & Scott,
The well-packaged shipment from you arrived this morning – fast delivery!
My slip neighbour and I both greatly appreciate your response and help with this matter – a class operation.
I will help M… with his oil flush and we’ll start the Decarbonizer treatment.
Many thanks,

Douglas C, Victoria, BC, Canada

I do not have enough good to say about these products!!
I own a 2002 Peugeot 308 with a 2.0 turbo diesel. (mileage: 290K kilometers/180k miles)
When I purchased this vehicle it was at 150k (93K miles) and felt under-powered due to the mileage.
I contacted Pro Maintenance Additives and spoke with Scott, and asked if he felt their products could help my small diesel car. After asking me some questions about the car, he suggested I use 3 products.  I used the oil flushing treatment, and I have since been running the FTC Decarbonizer and the CRD Fuel Enhancer in every tank.
Scott is extremely knowledgeable and helpful when it came to helping me sort my concerns and needs with this little diesel. (Do not hesitate to contact him, he is a joy to work with.)
Frankly, I am still in awe of the vast difference in the throttle response and power difference while driving this little car, even after the first two treatments.
When I first purchased this vehicle, before the treatments, I was getting an average of 950km per 55L tank of fuel (5.7L/100km, or 41MPG). Since treating the engine with these products I have been getting 1150-1200km (4.6L/100km, or 51MPG) from the same tank. Roughly a 20% increase in fuel economy!!
These products pay for themselves every time I need to go to the pump.
I am a firm believer in these products, and will be using them in all my diesel vehicles from now on.

Brian M. Queensland, Australia

I want to let you know, this stuff is amazing! I bought an old Dodge Ram with the 5.9 Cummins engine, about 200,000 miles on the clock. It was very low on power, clouds of exhaust smoke , and had lots of blow-by. I got the FTC Decarbonizer from you and added it to the fuel. Seriously, within about 2 hours of driving, I could tell the power had improved noticeably, and the blow-by had reduced significantly. I was shocked at how well it worked! Now I’ve done about 1500 miles, and the exhaust smoke has completely disappeared, and it’s running much smoother! I’m getting the Flushing Oil Concentrate from you now to finish the job right.

William M, Menifee, CA

My Peterbilt 389 with the ISX-15 was burning tons of oil and had bad blowby. It’s got around 500,000 miles on it. I was going through about 3 gallons of oil every 1400 miles. So I started using the FTC Decarbonizer I got from you, hoping I wouldn’t have to get a rebuild. Within about a month the blowby had slowed down a lot! And the oil burning is right down too, now I only need to take 1 gallon of oil with me instead of 3 or 4 gallons. I’m confident that will improve more as I keep using the FTC Decarbonizer. I’ll use the Flushing Oil Concentrate in about 3,000 miles when the oil change is due. Hoping that’ll tidy up the last of the oil burning. Thanks for your help.

Steve B. San Diego, CA

The FTC Decarbonizer has worked well with my Nissan Caravan 3.0 ltr Diesel, the DPF used to clog and need a regen and reset every 3-4 months. I haven’t had to plug in and run the “clean’ since March 2020 (it’s now March 2021). Thanks Team, a great product that does what it claims!

Ross D. New Zealand

I bought the FTC Decarbonizer for my 2009 BMW X5 Diesel mainly to help it with California’s emission rules. It only had 82,000 miles but wasn’t passing emissions. It also had a DPF problem, it was having to do forced regenerations far too frequently. I’d like to tell you that since I’ve been using the FTC Decarbonizer I’ve noticed some major improvements in the car. It now idles totally quietly (none of that usual BMW Diesel engine rattle), the MPG has greatly improved, and the regenerations have significantly decreased. It now runs like a different car. I told my brother to get some for his diesel car!

Matt V, West Hollywood, CA

We got the Blowby Pack to see if it would help our 2003 Dodge Cummins 5.9 24 valve engine. It’s got 300,000 miles on it and it’s been having some pretty bad blowby happening, as well as a lot of black exhaust smoke. We used  the oil flush treatment, and have been running the FTC Decarbonizer in the fuel. We’ve only done just over 100 miles and already we’re seeing an improvement. The black exhaust smoke has completely stopped, it’s running so much smoother, power feels to be up from before, and the blowby seems to be starting to slow down. I think that may take a bit more time yet. I honestly thought the engine was in really bad shape and was heading for a full rebuild – $8000. We’re really happy with the results. These products seem to be doing as you say they will. We’ll get some more soon for our daughter’s 2003 Ford Powermax. Thanks, a great product.

Diesel Toyota Land CruiserI finally got to put the CRD Fuel Enhancer in my Toyota Land Cruiser. It has around 252,000 miles and yesterday when I first put it in the tank I did not notice any difference, but today when I started it I noticed that the motor was more quiet than it usually is at first start. And my friend who used it also in his diesel Land Cruiser found a big difference in power and also said his is also a much more quiet motor.

Johannes G. Iceland, Europe

Our 2012 Kenworth with the Paccar engine was really having a major problem with DPF Regens. The engine has around 500,000 miles. It was doing a forced regen around twice a week, and the light was constantly on a lot of the time. We started using the FTC Decarbonizer and within a couple weeks we noticed things were improving. The check light hadn’t come on in over a week or more, and now 3 weeks later it completely stopped with the forced regens. And we’ve noticed the engine seems to be running smoother and stronger. From what we’re seeing, this stuff works. Thanks.

'91 CorvetteA friend bought this 1991 Corvette recently. It’s only got 139,000 miles on it, but it obviously had a bad maintenance history. It was still running great though and had good power, but the engine blowby was very bad. The pressure in the crankcase was enough to blow the dipstick out and oil was literally pumping from the tube. We did a leak down test and every cylinder had 20% or more drop. I followed the directions for using the Flushing Oil Concentrate, the oil came out looking very brown for brand new oil. The blowby pressure reduced a significant amount, the dipstick didn’t budge at all, and when I take the dipstick out now, there’s only a small amount of pressure there. The amazing thing was I did another leak down test immediately after the flush, and now it’s around 10% – 12%. We’re going to get the FTC Decarbonizer in the gas tank now and expect to see the blowby decrease even further as the rings and cylinders clean up. Very happy with the result!

Dave D, Belleville, MI

2003 Silverado DuramaxMy 2003 Silverado Duramax had lots of blowby. It’s only got 242,000 miles, mostly pulling a 5th wheeler around, power was still good. I got your Blowby Pack and got the oil flush done. Before the using the Flushing Oil Concentrate when I was stopped at traffic lights, I could see blowby coming out each side of the truck. Now within a couple days the blowby has reduced by about a half, definitely a lot less blowby smoke, I’ve got to get down and look under the truck to see, and now there’s only a little bit coming out. I think the more I drive it now using the FTC Decarbonizer in the fuel will probably fix the last of the blowby. Good products.
