Great product!

It works great, I've only used it twice and the injectors are like new.

Just bought RV with diesel and want to treat it well. Clean up engine

Not sure if it's cleaning my injectors, but after the first full treatment I noticed a pep in my engine and my mileage went from 10.8 mpg to 12.2 towing a light load on the highway. Would recommend!

Use this product intermittently to maintain my 2022 Chevrolet 2500 HD 6.6 Duramax. Never an issue and awesome performance and fuel efficiency.

Have used Amsoil diesel injector cleaner for years have never had no problems

Until recently, I had never run an injector cleaner through my engine, but I thought maybe it could use a little TLC. I felt a definite improvement in starting and idling after about 2 tanks of this fuel injector cleaner!!! I’ve chosen to run it ever since. Overall, my truck runs so much better at 376,000 miles, with the use of Amsoil products, than it ever has!!!! Thank you!!!!

Been using this cleaner. Don't known if it's doing any good. Still haven't received any of the free gifts that were promoted when spending certain amount of$. I well excited the dollar amount. Let's see if anyone from the company will deliver my promotional gifts.

I started smelling a coolant leak and could not track it down. I brought my truck into the dealership and they could not track it down either. YT videos made me believe that it may be a cracked coolant tank so I ordered a new one and replaced it. I still had a leak and it was coming from the coolant tank somehow. I brought it back to the dealer and they found that I was getting combustion blowby into the coolant system and it was pressuring the coolant tank and it was slowly overflowing. They said the two probable causes were a blown head gasket or a bad EGR system. Neither repair option was going to be cheap. I had heard about the miracles that Amsoil Diesel Injector Clean could perform and ordered a case because I had nothing to lose by trying it. I used the cleanout dose with a full tank. Within 10 miles of adding the product to the tank, I saw billowing clouds of blue smoke coming out of the exhaust under mild acceleration. I treated one more tank at the cleanout dose and that did the trick. Apparently, I had a carboned up EGR system and Diesel Injector Clean got rid of it fast. I now treat my diesel with it regularly and have not had a EGR blowback problem again.

All Amsoil products are superior!
