We favor to, in ~ minimal, "wet" the filter by filling it through ~1/2 a quart of fresh oil.

• through the gasket appropriately lubricated, install the new oil filter in the same fashion you eliminated it. Perform not usage an oil filter wrench come tighten the filter. Snug the filter so the it seats tightly against the mounting surface. There is no should overtighten the filter, merely tighten it as lot as feasible by hand.
