Great power great batteries

Been using this stuff since the 70's does just what it says it will do my grandma didn't change her oil like she should have clicking lifters put this in and sent her on her way next time she came by no noise coming from the engine pulled the dip stick and you could visually see where it was in the oil because that part of the dip stick was shiny clean! I had a 1966 Lincoln coupe that belonged to a Dr it sat for a while and was not driven much I got the car and it burned one quart of oil going over the pass to the beach and back less than 100 miles I put a bottle of this stuff in the crankcase drove it over the summit I went below the speed limit until I hit the final grade then put the pedal to the metal and let it go till I got to the top after I went home I topped it off and it loosened the rings and never burned a drop after that… This stuff is not snake oil it does what the label says it will do.

Good deal that works.

I added this product along with a quart of AT fluid to my daughters car. It had some sticky valves that were ticking and knocking. After a couple weeks, the car seems to be running a lot better.

It stopped the ticking sound!

I started using Rislone as an additive to my oil change years ago. I had a BMW with a slight ticking sound. After adding the Rislone, it was gone. I became a firm believer and have been using ever since.
