Ok guys I just switched from a semiconvential 10w30 to castroil 10w30 nextgen full conventional. Immediately after start up I noticed that the engine sounded like I could hear the oil pump making noise. Not really like a grinding or anything just that the pump is audible. The oil pressure is good, acting the way it should. I only hear the sound when the car is cold, it just "whines" I guess you would say nothing super loud or obnoxious but I can definitely hear it. Should I go to something a little heavier like a 20w50 fully synthetic?
Any recommendations?
