Sorry I've never changed the oil and filter on a car before, will be doing it for the first time soon. Can someone please explain what the gasket is? Is it the black rubber ring that's already on the Napa 1333 filter? I noticed that on the past dealership invoices, they always charge about 50 cents for a new gasket with every oil change with their 06A filter. Does this mean the OE filter doesn't have a gasket so it always needs a new one bought separately?
