I have heard if you have no leaks now, possible to get a leak after switching to synthetic. That is one reason I have not switched for my '94 530i. I have a neighbor with a '92 525i who just switched and did not get a leak. I am already rolling the dice with my nikasil engine with 115,000 miles and running great. You will never know if your will develop a leak until you try.
