How well does Rislone Concentrate work?

If you want a better clean - you would be better off running a 10w-30 diesel oil - - they clean up much better than mmo or rislone.

Run the 10w-30 for 2 OCI's

BG EPR? What does the EPR stand for? Still haven't changed the oil, but have PHM 10w40 ready to go in with the Rislone after a flush before the change. Maybe I'll try the BG stuff next time if this doesn't take care of it.

I actually changed oil today. Did the engine flush prior, filled with the rislone concentrate and pennzoil high mileage 10w40. Still get a rattle around 1700-2100rpm I'd say. Couldn't find anything underneath with a rubber mallet. Hope it isn't timing chain. Not trying to spend that much on an 03 maxima. I recently installed a new pcv and oil catch can but rattle still there. Seems worse when engine is hot. Part throttle only. Doesn't do it in park or neutral. Bugging me!
