This product has cut down on down time caused by the bad fuel by cutting down on regen's by half. I have not done parked regen for months, my Cummins suffered from carbon build up 590,000 and still getting 6.8 in fuel economy, extra cost has been offset by less repair time

What I wrote on Amsoil Cetane Boost is true for Amsoil Injector Cleaner. Let's face it, diesel fuel is some of the dirtiest/contaminated stuff you can buy. Let your fuel delivery system crud up - it gets really expensive; fast. With regular use of Amsoil Injector Cleaner, my engine starts easier ( even when cold), runs smoother, and improves my fuel economy. You think Amsoil products are expensive? Try pricing replacement fuel system parts.

Just it is insight

I use Diesel Injector Clean at every fill up and I feel it helps keep my truck running smooth

I use this injector cleaner as well as AMSOIL's cetane boost at every fuel fill and the engine seems to run a lot smoother with no hick-ups ever. There did seem to be a very slight increase in fuel economy as well. It is very cold here in the winter so I have been using AMSOIL cold flow in addition to this product and the Cetane boost and although we haven't had any below 0 degrees Fahrenheit mornings yet, I have not had any gelling issues. I will continue to use all 3 diesel additives in my fuel due to the luck I've had so far.

I noticed improvements in fuel economy during long trips. But not much within short trips and around town. I will continue to use the product and possible try out the winter treatment.

About every 3 to 4 fill ups I add one bottle of injector cleaner into my tank. In the winter time I reduce that to 2 to 3 fill ups and use the winterized injector cleaner.

add to every tank of fuel

I love amsoil to protect my vehicles will always love to use this product. I am trying to get a tee shirt to promote amsoil

I use diesel Injector clean at every fill up per the product recommended dosage It is important to me to keep the internal engine and it's components clean. The lubricity that injector clean provides will give my Cummins Fuel pump a long life. My vehicles are fully protected with all Amsoil products

I use Amsoil fuel injector cleaner with most fill ups. My truck has 139000 miles and still runs great.

THis product got rid of the black smoke bellowing out the exhaust and increase my miles to the gallon by 2 miles. The truck run FANTASTIC! Will buy more.

Works as promised

I use this at every fill up

Works great cleans injections

I've been using amsoil products for ten years or so and the proof is absolutely in the pudding you don't have to take my word or anybody else's just try it and you will judge for yourself five star service for a five star product thanks amsoil. I've been around diesels my entire 47 years.

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.

Great products from Amsoil . I have been using their products for years .

10 year old Duramax still going great.... always with AMSOIL

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
