Regarding leaks. Synthetic has smaller molecules or something like that, so it is more likely to leak through a weak seal than conventional. So if you didnt have any leaks you shouldn't have any now unless any seals are just barely holding up. The notion that synthetic causes leaks isnt true.


Correct. Dino oil molecules are long chains, where the synthetic oil molecules are much smaller. A marginal seal or gasket can hold dino oil but can leak synthetic oil with no other changes.
