Oil anti-leak additives
I see about a dozen different brands/varieties on the shelf claiming to stop engine oil leaks. The prices vary widely. My old rarely driven van drips about 2-3 drops per day at most (stored over pan) and if I add anything to it's oil I want it to work and to do no harm. Any recommendations on which is best anti-leak brand to use for a faulty gasket that would cost about $1000 to replace? Thanks for any advice.
