im getting ready to do my oil change and when i think about it i dont think ive ever seen a washer there. do our cars have drain plug washers? worried that i lost mine and havent been using one for a long time...

 

There is not a drain plug washer. Simply be sure that both mating surfaces are clean.

 

if you look at the factory drain plug it has a rubber o-ring gasket part# F75Z-6734-AA
retail $4.05, if you purchase a new factory drain plug part # F75Z-6730-BA it comes with the gasket for $8.32
