I don't normally count on things like this working, but what the heck for 5+ bucks ill give it a shot. I used it in my 1998 Jeep Wrangler because of about a 5 to 7 drop RMS leak. Jeep takes about 6 qts of oil, but I use 5+ qts and this 16.9 oz bottle. After about 20 to 30 miles heavy driving drop...

Seems to gunk up the leaks good with every Bars product. I stick with them and Lucas. Careful in winter, because the oil pressure climbs with thicker additives !

My VW Passat V6 had a leaky cam seal plug , leaking oil on the exhaust ( common on Audi and VW V6 Engines) Causing burnt Smoke coming from the vents. After a week the smell is gone. These additives dont always work due to torn gaskets or big cracks but so far is working on my 1999 engine.

Works quite well actually.

It appears to have stopped the Rear Main Leak on my 2007 Northstar Engine.
