Well I can say that this stuff is the bomb when it comes to cleaning the insides of your engine and doing it safely and efficently.

 

I tried it in my father-in-laws NorthStar engine and it really did the trick. His engine use to use a quart of oil in 2k and now barely uses a quarter of a quart in 3k. You can only get it online at AutoRx.com. I will admit it isn't cheap but it works.

 

If you want to read up on others that have tried it go to bobistheoilguy.com and read up on it in the additive, fuel, oil, cleaners section of the forum. I have been over there doing some reading and have yet to find a bad post or even a netural post on the stuff. Like I said it worked great for me and my father-in-law's North Star engine. I have a friend that is trying it on his truck with 159k on it. So I will see how it works for him and what he things here in a few months or 2k miles or so, which ever comes first.

 

So if you have a high mileage engine, like one over 100k and think it needs cleaning inside. Give this stuff a try.
