Customer Ratings & Reviews

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.

I use this product all the time to ensure my fuel system is clean and lubricated. Works great!

I have been using AmsOil Injector Cleaner every tank full since I bought the truck at 92,000 miles and now at 109,000 miles I had to replace the DPF and now the injectors need replaced and they just went on national back order. IMO this cleaner is worthless.

Did the job. What else can I say.

had an injector sticking and used this product and within the second treatment it was corrected.

Great stuff, first time I have seen an additive make a deference in the way my truck idled. Smoothed it out.

After a $7,000 bill for replacing fuel injectors on my 2004 Duramax 2500 GMC, I started using AMSOIL Diesel Injector Cleaner. I have not had any more injector problems sense that time.
