I was wondering if anyone knew if my car had an anti-drain back valve on the engine... its a 92 caddy with 4.9 engine... recommened filter is PF-58... which has no valve, so I was wondering if i should definetly use lets say a super tech 3675 with a drain back valve in case...
if my engine has ADBV on board, ill continue to use the PF-58....
