Ok, guys I drive a pos 05 Chrysler Town and Country. It has 75,000 miles on it. For the first 50,000 miles I either used Valvoline 5w20 or MC 5/20. I then use Mobil 1 5w20 syn. for about 15,000 miles and then went back to MC 5/20. My engine is leaking oil from around the intake manifold and onto my exhaust. Would this be cause the the use of syn. oil?
Does a semi synthetic cause leaks?
Should I try a high mileage oil or just go up to a 5w30?
