Hey, My first post in many years! and maybe my last.

I haven't used oil additives in decades but decided to give it a try again on my 2007 220,000 mile 5.7 Ram. I chose Rislone Hy-Per Lube because of price and they've been in business a long time. The truck had been sitting over-nite so it was cold out(Ohio) and was down about a quart. About 5 minutes later all the ticking was gone! So I'll be using Rislone for now.
