Back to the Berryman treatment for the crank case...
My car was a fleet vehicle & the oil may not have been changed as often as it should have. It was sludgy in there. I put the Berryman in with my oil at 60k miles - just before an oil change (read the instructions). Cleaned the engine up great! It sparkles inside & I now run Mobil 1 with no leaks - that may be because I'm lucky.
