During an oil change yesterday I was surprised to see a fresh leak of oil running down my Pure One oil filter from the engine ...Upon closer inspection the oil filter had backed off quite a bit and could easily be turned with just a few fingers . The instructions say to : " Pre-oil gasket then hand tighten until rubber gasket makes contact with the engine oil filter base plate - then hand tighten an additional 3/4th of turn " ** Note to the wise : Hand tighten a good turn and a half to two turns until HAND TIGHT !! the new "easy off" rubber gasket material used on oil filters today can back off on you if your not careful ! ...I would rather have to possibly use a oil filter wrench to remove an oil filter than to risk a oil filter backing off and running the sump dry on a remote stretch of highway .
