Noticed on an earlier thread an individual used Motor Medic Motor Flush on his Cadillac and wanted to get feedback on RISLONE that I started the thread on. Even though I use good synthetic oil in my Ram in signature -- I would not mind adding this to the Crankcase for the last 1000 miles of my oci. Says on the bottle -- RISLONE High Mileage Formula Engine Treatment -- Conditioner & Cleaner. 1) Cleans, Restores & Protects 2) Quiets Noisy Lifters & Valves 3) Reduces Friction & Wear Dale Ps. Hopefully everybody has a safe/happy Memorial Day weekend.
