Review on High Mileage Engine Treatment: Restore Your Vehicle'S Performance With Rislone 16.9 Oz! by Black Holstead
have to assume it does as it says
I like to keep my engine squeaky clean on the inside. I use Rislone and alternate with several other brands. All I can say is that, I never have any form of sludge buildup or grunge in my engine. I can eat off the internals given that everything is shiny clean and free of any surface buildup. Of course that must go hand in hand with using a good quality oil changed regularly.
Pros
- Use this stuff all the time
Cons
- Not always readily available for purchase
