Ontru's Oil and Oil Filter Change Guide

[timmyj51]

They recommend you also change the drain plug washer every oil change. A replacement washer has been
included in every filter I've bought, but don't know about K & N (a brand I wouldn't use. Only Bosch/Mann for
my car).

I did have a replacement washer with my filter but strangely it was thinner then the OEM so I decided against using it.
