Great stuff
Works well. Used to do a quart of 2 stroke per fill up. Now I just use this stuff. Keeps engine nice and quiet like the 2 stroke oil didGood stuff. (06 5.9 cummins w/345k)

Good insurance
This brand was rated high in the diesel forums. While I can't tell if how well it works, it is good insurance for my diesel engines. I have a 50 gallon tank to fill my diesel tractors and engines; I just pour suggested amount before filling my tank. I also add to my diesel truck tanks before fillup.

I love this.
I love this. Actually makes my Mercedes RV run quieter. No more injector difficulties on cold mornings either. I now buy the gallon, and refill these to carry along.

Lift pump seems happier as well as slightly quieter injectors
Ran two tanks full through, definitely has lubricating properties. Lift pump seems happier as well as slightly quieter injectors.Will be using again!
