Used this in my 2011 Ram 3500 with 110k miles. Put it in before we went on a trip from Alabama to Virginia expecting to notice some sort of difference in throttle response or mpgs, but not so much. I'm a firm believer in Amsoil oil in all of my vehicles but this just didn't seem to live up to expectations. I'm sure it did some unseen good for the internal components, just nothing noticeable.

Always loved using this product. The case of 6 fits perfectly in my toolbox. I have a 2005 F-250 with the 6.0L and still have factory injectors at 222,000 miles. Plus the added fuel mileage is a bonus.

I have to admit he Primary reason for starting with this, I simply wanted to give every chance for my injectors to "live" as long as possible, along with the also, very expensive Injector Pump. Alongside, with a Fass Fuel pump/separator, I really feel these components will last through "my days"!

I have tried the injector cleaner on my 2007 GMC LBZ with 330,000KM.
I have had more
smoke on startup in cold weather -15 to -20 Deg C.
I have been using the Amsoil injector cleaner for 3 tanks of fuel and found no difference.
I purchased GM upper cylinder injector cleaner and found a major difference.
GM upper cylinder injector cleaner requires you to mix 1.6 L of diesel with 1 container of cleaner and run the supply and return fuel lines out of a container.
I takes about 45 minutes to run the cleaner through the engine at elivated idle.
This clean has changed the cylinder balance rates back to normal all injectors are within 1-3 in park and 3-4 in drive.
I was hoping for Amsoil to make a produce that would do a better job of cleaning diesel injectors and returning balance rates to normal for injectors with high mileage.
The produce is not worth the price and time. Hope the engineers can come up with a much better product.
Sorry for the negative reply on the product. I do use Amsoil in everything else on my truck thats why I gave the injector cleaner
a try.

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
Reviewed by Resolute:
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.

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.
