I have never had a problem, even with my current ride that made the switch at 178 miles. Dirtiest engine I have ever seen! The problem with oil leaks is that gunk settled over the seals and the gunk hardened, causing the seal to dry out from lack of oil. In most cases, the synthetic will clean off the gunk gradually and light oil leaks are produced. These oil leaks usually resolve themselves after they are able to swell with the oil.

Of course, there are exceptions when the seals are so dried that they crack.

Just go ahead and make the switch.
