Changing different brands of oil,even different weights will not cause oil leakage.Personally,I would run 10w30 year round in PA,but that's my opinion.
Dodge Caravans.....it's the valve guide seals that make them smoke,and this is only on the Mitsubishi 3.0L engine.The 3.3 and 3.8 Chrysler built engines do not have this problem.
