I bought a used lincoln town car executive and the manual said synthetic oil should be used but I just had an oil change using high mileage semi synthetic oil. Should I have any concerns about using this other oil instead of the full synthetic oil? The car has over 200,000 miles on it.
My car has 216480 miles.
My car has an automatic transmission.
Hi there. If you asked this question about 10 years ago - then yes, you might have issues with seals or gaskets wearing prematurely. However, as technology has improved, the gap between semi-synthetic and full synthetic is not as big. You should be just fine without having problems.
