Otherwise I'd blame it on the molasses oil you had in there. Wtf 15w-50...
10w-30 is good for very warm climates or summer. 5w-30 is preferred and good from warm to very cold.
No oil leak at all. I live in socal, so 10w30 or 5w50? I just picked up a 98 ser yesterday, I want this one to last me much longer than 1 year. It doesn't get very cold here, mid 70's to mid 80's inland year around. Winter time a little cooler, is it safe to change oil weights back and forth? Say in the summer 10w30 and in the winter 5w30.
