Hi all,

I'll make this quick. I've noticed a leak on the oil pump cover plate
after switching to Mobil 1 15-50W last week (less than 1200 miles on a
GEX rebuilt). I am considering switching back to Castrol 20-50.

Therefore, my question for you "has this strategy worked - switch back
to dino oil to eliminate the leak?"

Thanks in advance for your patience on this repeatative subject.
