Quick Question: What is the latest you can switch to synthetic (mileage wise) without it causing any leaks or anything like that?




There were issues with Syn ausing leaks when it was first developed, but that was back in the day like long before the contour was even being designed.

Its totally safe to do it at any millage and should not induce any leaking that wasnt already there to begine with, which should be addressed anyway.



not true.... i switched over at 85k or so and lost 4 quarts in 2 days.....
