This car gets mostly highway miles. The car was usually in vermont and the oil was in service for the coldest months of this past winter. 10w30 seemed to do allright with no abnormal sounds on startup. Motorcraft oil filter and relatively new fram air filter (Ill have to check for leaks). 87K on car at end of OCI.
