1925 Franklin gas in oil. in General Discussion Posted Wednesday at 11:52 AM 11 hours ago, edinmass said: Drain and fill the crankcase. Disconnect the electric pump and go back to stock. Pull plugs and crank engine with new battery till you build oil pressure. Put a little bit of oil in the bores before you install new plugs. Start and drive the car like you stole it.........couldn’t be simpler! Ed, Drive it like you stole it??? In the case of a 1925 Franklin , you will be beside the road in about 30 miles with a hole in the crankcase and oily parts on the road.
