Mobil Clean 5000 for you, and I bet you'll save money. You could run Mobil 5000 longer too if you wanted to change the filter every 3,000 miles like RP says to do.

i doubt if oil weight had anything to-do wth stopping an oil leak and using a thicker/heaver oil reduces HP and can actually lead to scuffing of engine parts, which equals more wear, loss of HP and a decrerase in fuel mileage.....
