Believe it or not there is a cleaner for internal engine. I work at a blue oval deal, but i still drive a ls1!!, we got a new cleaner from our distributor, ProTec. It is a cleaner you put in the oil and run for approx 20min before you change oil, cleans out the cyl walls, piston rings and bottom end. All of our techs laughed but once we demo ed this stuff it was amazing. I ran it though my Ls1, and it raised up the compression in the cyls and ran alot smoother on take offs. If you guys know where to find ProTec products find this engine flush and use it. Well worth it. recommened about every 15-20K, Just wanted to let you guys know!

 

Engine flush has been used for ages to clean stuck rings and dirty lifters. Traditionally diesel has been used in the oil ... I bet diesel or something close to that is major part of your product as well.

 

Amsoil makes a product of their own. Awesome stuff!
