question about going the full synthetic route on 92 w, 140,000 miles. I read all of the info. I could find, and I'm looking for a final opinion. I believe synthetics to be worth the extra cost. However, with their engine cleaning properties, I am afraid that I will develop more oil leaks. I have a very small leak coming from either my valve cover or my rear main seal (not sure yet). So, although I'd like to switch to Mobil 1, I'm afraid this will cause more and bigger leaks to start form this higher mileage engine. I understand that the crud that could be sealing up leaks is just a mask for the problem, but would i be better off just sticking to regular oil? Any opinions greatly appreciated.
