Synthetic oil use in 01 explorer 4.0 SOHC I purchased my 01 explorer at around 50,000 miles. At around 75,000 miles I started using synthetic(not blended synthetic) oil. At 81,000 my rear main is leaking and is currently in the shop getting fixed. Once I get it back should I keep using synthetic oil or go back to using the standard oil? My warrenty runs out in about 3,000 miles so I don't want to chance it again.
Thanks for any imput
