Liqui-Moly "Motor Oil Saver" for valve stem seals

[hyperscion]

it worked in a 1989 jeep. it did not work in an old ford car. not sure of the nature of the leaking problem,,but its cheap and worth a shot.

1,000 mile update. The engine still consumes oil, but noticeably less. Probably about a quarter every 2,500-3,000 miles now (was a quart every 1,500 miles). Haven't noticed any smoking from the exhaust yet.

Found this old thread ? Any other users or ideas ? Guy I’m working with has a 2008 BMW 750 … he wants to keep driving it but shops are warning him about the cost of valve seals on this car … N62 ?
Wonder about Redline or Motul to get ester that way … He runs Royal Purple 5w30 …
He wants to be proactive if there is such a thing …

What you want to do is add one bottle to each 5 quart jug so you maintain the proper mix ratio. Then your top off oil has it too.

I have had success using it in your engine on more than one occasion, as long as it is used at the first signs of smoke and not when they make 007 screens.
