It works 100%. Duramax LBZ
“100% these products work as you say! I’ve been running the ULS Diesel Enhancer and the FTC Decarbonizer for 6+ years in my Duramax LBZ. And they work! I love these products – they do as you say.“ Jean R, Great Cacapon, WV.
Read MoreSo much better!
“I’ve been using these products for years with good results every time. A while ago I picked up a secondhand small single-cylinder diesel-powered inverter generator, and it was running like a dog. I did the usual bits and pieces to it and thought it was running much better after that. After a while I thought…
Read MoreRuns like brand new!
“…the money it has saved me over the years, wouldn’t run without it…” “I’ve been using your ULS Diesel Enhancer in my 2006 Dodge Ram 2500 5.9 Cummins for many years now. It’s been a lifesaver! It still runs like brand new. I’ve never had a single problem with the engine in all the time…
Read MoreNight to day difference
“I got your Stop Smoke Diesel Pack for my old 2006 Ram. 5.9. It’s got 286,000 miles, and mostly it is running fine, or so I thought. You can really tell the difference from using the fuel treatments (FTC Decarbonizer and ULS Diesel Enhancer), it’s like night to day! I’ve not done the oil flush…

Read More6.7 Powerstroke never been better!
“Our 2013 F250 Lariat, 6.7 Powerstroke has had problems for a while now. It’s got pretty low miles for its age, and it was down on power, bad exhaust smoke, noisy idle. I’ve owned it since new, I’m a very particular person, it’s always been serviced above the recommendations. I’ve tried many products to fix the…

“Just wanted to let you know that I’ve been using your diesel additives for three fills now and THEY REALLY WORK! But of course you already know that. My old Land Rover Disco 3 diesel is running really smoothly and definitely has considerably more power.The difference is clearly noticeable — if she was a horse, you’d say no way…
Read More1978 Blue Bird Wanderlodge
“My 1978 Blue Bird Wanderlodge had been having a white exhaust smoke problem for quite a long time, and it was slowly getting worse, and it just ran rough. It didn’t miss, and the power seemed normal. It has the Cat 3208 engine, with only 100,000 original miles. It sits a lot, I don’t drive it as…
Read MoreTwin Diesel Marine Cummins
“We have a recreational boat with twin 8L Cummins marine engines. They’re 21 years old, but only have 1780 hours total. Over the years we’ve done regular oil changes and maintenance. We thought that was enough, but it seems that was the downfall. The boat sits a lot (obviously) and has a lot of long…
Read MoreISX15 Oil consumption fixed
“My ISX 15 Cummins has around 750,000 miles, and started using a lot of oil over the past few months or so. The cost of an inframe overhaul was not good. I decided to go ahead and order your products and did the oil change flush about 10 days ago. Great stuff! Usually the new oil is…
