Just a quickee................

It doesn't go in the oil!!!!!!!!!!!!!!!!!!!!!

Remove the spark plugs and put the BonAmi directly into the cylinders and crank her over....Use air to blow out whatever you can from the cylinders.....Start it up....Let it run for a bit....Change oil and filter...See what you got....Sometimes better...Sometimes not...It's just a bandaid..

GM also had TSB's about helping ring seal and oil consumption by using GM Top Engine Cleaner in Gas & Diesels.....Gas it went down the carb and diesels it went in thru the glow plug holes...

Just a crutch...
