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!

Had a Volvo mini Excavator, first start up in morning it spits and sputters till it warms up 1-3min then it fuel knocks till it runs for atleast 10-15min, add this stuff to fuel, ran for 30min, came back Monday morning fired it up and it was better. Treated 2nd tank of fuel, by end of 2nd tank 2-3days later, Fuel knock was 95% gone when cold and the spitting and sputtering was cleaned up. It does start coming back a hundred or so hrs later of untreated fuel so I start treating next couple tanks till its gone again. Very happy with this product vs Power Service that I've tried in past. This stuff actually works and it works faster.

Haven’t run injector cleaner in years, but my ‘98 Dodge 3500 dually diesel 4x4 is running like a Swiss watch with 372,000miles on the odometer. I DID notice that it was running even smoother with this Injector Cleaner in it!!!

Us this in our diesel engines, have never had an injector problem.

Better fuel mileage

I use this product religiously and add to every tank of diesel I put through my truck. The engine runs smooth and burns clean. Most effective and affordable product on the market

Love the product as it gives me piece of mind in keeping my trucks motor in top condition. Injectors costs too much to replace if you break them.

My car has had amazing power since I have been using it. I use it in every third tank and it has really cleaned up my engine and performance is amazing. Highly recommend to everyone who drives a Diesel.

It worked as described.

I use this product every fuel up. Keeps my diesel running smoothly and reliably

Keeps my diesel running smoothly and powerfully.

Seamed to do the job thx guys

I use this product regularly on my 6.7 L Ford. It now has 97K miles on it and I've never had a problem with the fuel system except twice when forced to buy bio-diesel. In the first case, I had a missing problem after about 100 miles; I didn't have this in the tank at the time. In the second, I did duse this in the tank at the same time and didn't have any issues. I'd recommend it to anyone, especially if you're forced to purchase bio-diesel.

Used this diesel fuel additive in my 2018 Ford transit work van with a3.2l diesel. It has 212000 klms on it and runs like new. Can't have downtime as my job is busy. I think it helps keep the check engine light off as well and running smoothly!

I feel a difference right away putting this in my fuel.
