Lucas oil stop works..
I was wondering what some of ya'll guys thought about this product because I have read some threads that says its bad for our cars. Is there any proof to back up the claims. I read something like it bubbles and cause's gook to build ,but there was no heat added to the test, would that make a difference?
depending on the oil you use, especially with synthetics, some may "thin" out enough to seep through older seals, try changing brands or viscosities rather than putting an additive. If it still leaks and you've hit 20w50, I'd try to find the worn seal it's leaking from.
