Is it still necessary to change automotive crankcaser oil in 6 month max intervals
I have a '92 Ford F250 that states the need to change the motor oil at 6 months or 5,000 mile intervals. With the newer oil types around I wondered if the 6 month oil change interval still applies.
This is up to you. I would change oil every 3,000 miles with an older truck like yours.
