Customer Ratings & Reviews

My Ram 3500 has 50k miles on it and after using this in one tank I could tell a difference in the throttle response after a week. I recommend this product.

I like using the injector after coming home from a long trip. I can tell that I have gotten questionable fuel along the way by the way my truck runs at idle and low speeds, Amsoil injector cleaner cleans it up within a 1/2 a tank. Truck runs smooth again and my mileage is back up. This last 2000 mile trip I also used the injector cleaner/cetacean booster at a couple of off the path fuel stops. Amsoil products work better than others I’ve tried in all of my trucks!

Used this to help my diesel trucks fuel system. No issues!

Since I added the solution to my tank I the difference between before and after more power like when I got the truck at the dealership.

Very good product that I have been using for years.

It does what it said it will do

Works as advertised!

I run this in my 6.7 power stroke and is a great additive that I will continue to use

When I don't need the cold weather anti-gelling protection that Amsoil's All in One offers I run this for the same results aiding in cleaner combustion and a smoother sounding engine. Particulate emissions are noticeably less while using Diesel Injector Clear, particularly when the tractor is under load.

Good till the last drop

Its works. Buy it.

I am not a fan of mechanic in a bottle, this diesel fuel system cleaner will solver msny common probles and prevent them from reoccurring or happening in the first place. I run it in every drop of fuel I burn in three different engines I own. Amazing results.

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.
