We are currently on on 7500 mile trip out West and have added one ounce pure 5 gal. of diesel - towing a 5th wheel travel trailer. I run Amsoil 5w40 oil and a dual bypass oil filter system. Great products.
I try to use it every fill up my car runs very smooth and doesnt smoke as much. My 1991 mercedes 350sd gets much better mpg and hp. People are always asking if i did something to my car. Thank you
My Yanmar 420 hp Marine diesels ran 17 seasons, 2400 hrs and 38,000 miles with no service or repair to the fuel system other than filters. When we sold the boat the engines ran like new and passed the survey with flying colors. There is no better proof of a good product than this.
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.
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.
Bottom Line
Yes, I would recommend this to a friend.

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!
