Cheap insurance

With ULSD fuel not having the lubricity needed by the fuel pump, this adds much needed lubrication. It also helps to clean everything and improve combustion. I have seen about a 5% improvement in economy.
I have been using this for a little over 2 years now as Maintenance and it works quite well. The injectors are quieter and with a slight inprovement in mileage, the cetane boost gives a bit more power with easy starts.
I tend to be skeptical with products such as this but I must say I was pleasantly surprised with the results. While it is difficult to determine what exactly is happening inside the engine I have data that confirms an increase in MPG of about 8%, just as advertised. I plan to continue to use this product.
It seemed to improve the performance in my 1997 Ford F-350, 7.3 power stroke. If been using the injector cleaner with no issues. I Would like to see the boost/cleaner sold in OZ marked containers for more controlled application
My 2008 RAM has just over 224,000 miles - it's had an AMZOIL bypass/oil since it has 11k miles. Decided to try this cetane booster/injector cleaner out. Filled tank up, poured 1/3 of the container's fluid in, and parked it. In the morning not only did it fire up instantly, but within first 3 miles there was a significant improvement on throttle response and power. I will "shock" the fliel system after another two fill ups just to keep everything clean and high functioning - very impressed with the product and quick, noticable results.
Great Product!! My truck runs better and fuel burns cleaner. The cetane booster helps save using as much diesel fluid.
Bottom Line
Yes, I would recommend this to a friend.

Great preventative maintenance product

With the cost of modern diesel injectors, adding a bottle of this every month or so is a no-brainer. It's easy to put your trust into anything Amsoil puts their name on.
Bottom Line
Yes, I would recommend this to a friend.

gave 4 because just started to use.
Seems really good for now and if it is like their other products I won't be disappointed.
I gave this a try for my 1997 Ford F350 Powerstroke. Well I can tell you now it's like running on steroids. My truck acted more responsive and had quicker acceleration than before.
I have tried many types in the past and only Stanadyne or redline came close. Definitely recommend this product.
As for the injector cleaning? I think it's working bu but all I can say is the truck runs much better now and they have the original injectors in there. 240k miles.
Definitely try it out!
