As with any engine, one of the keys to long life is regular oil changes and the DeLorean is no exception.
Except in extreme climates, we recommend conventional Castrol 20W50 motor oil, and specifically DO NOT recommend the use of any synthetic oils in the PRV engine.
Oil should be changed, with a new filter and sealing washer every 3,000 miles or a minimum of once a year.
The oil filter is a spin-on type with an anti-drainback valve. The ones we sell are made by Bosch. The Purflux filter is no longer available in the US.
The drain plug is in the front of the cast aluminum sump and has a square recess 8mm on a side that requires a special socket to remove. We carry these sockets. They are $18.85. Every time the plug is removed, the crushable washer behind it must be changed. Failure to do this will allow oil to leak from the drain. Every time.The oil capacity of a DeLorean engine, including filter, is 6.75 quarts.
