Synthetic Oil ???

My H3 always used 'regular oil'
Has anybody acquired oil leaks =after changing to 'full synthetic oil' for the first time?

+Motor has 77k original miles

Purchased an '06 with 142000mi and started using BG HiL0w30 with BG MOA additive. Previously had dinosaur oil. Started leaking out the oil pan gasket so I tightened it up. It could have be a coincidence. Currently 180000mi with no other problems except in burns plenty of oil in cold starts in below freezing temperatures, two quarts every 3000mi.
