well i serviced my car on the weekend and she runs smooth as, but today when i got back from work i spotted a oil patch under my car where it was parked overngiht, and so i checkd my dipstick and sure enough the fill level had gone down, i checkd the sump plug and she seems fine and i re tightened the oil filter
is there any other places it could be leaking?
Run the car up on the ramps again and get under the car with the engine running and a strong light. With reasonable oil pressure build up on engine idle you may be able to spot the source of the leak assuming it was not caused initially by the oil filter being spun on with insufficient torque to prevent oil escaping.
oil pressure switch??
