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

 

Nope, ran both of my H3s on Mobil 1 since first oil change, zero issues

 

X2^^^

 

It's gunna' leak like a sieve!

 

I've used Castrol's Synthetic Oil 5W30 since first oil change, zero problems.

 

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.
