I know people in this forum talk about Rislone and MMO being able to clean out an engine and help things like sticky lifters and such. Well we were cleaning out my dad's old speed shop to dig out a 348 Tri Power motor and found a case of Rislone he won about 10 years ago and just chucked in the back. I thought about dumping some in the wifes car and wondered if it would help finish off the sticky lifter that the MMO had helped quiet a bit earlier
