Customer Ratings & Reviews

It is so helpful and we can tell the difference

I have used the Diesel injector cleaner on my 2005 Duramax with every fillup since I purchased it with 116,000 miles on it. I now 185,000 miles on it pulling a 35 ft Fifthwheel RV and have spent over 6 months pulling it over mountains and thru high plains they last three years. My injectors have yet to fail me and I attribute it to my use of this product. When I purchased the truck I changed all the engine and drive train fluids over to Amsoil. Nothing but the best for our Duramax.

Noticed Quicker throttle response and improved Horsepower with just one treatment Will continue using this product as directed (Yanmar diesel)

Our first f-250 had over 300,000 miles with an untouched 7.3 motor. Our current f-250 has 220,000 miles, 2001, 7.3 again with an untouched motor. This is the only additive we have used in almost 30 years.

Saved My Eng. from a complete Injector job , can't say much more then that. Use as recommended and I would say your troubles will be limited.

Have used this for years in diesel pickups (RAM Cummins), as well as Volkswagen diesels. Added at each fill-up. Kept everything running smoothly and clean. Just bought a diesel motorhome. That's next!

So far so good, can't say anything bad about it.

Keeps my "Vintage" '92 Dodge diesel running great!
