Supposed to replace the washer with every oil change right?

Well I didn't for a few times and the plastic one that is there is showing a bit of wear. So I asked the local auto parts store guy for a washer for it and he asked me "plastic, rubber or aluminimum?" I wasn't sure... the plastic one wasn't holding up too well so I asked for the aluminimum one.

What do ya'll use and recommend?

 

i always get aluminum :dunno:
sometimes ill leave it on for a couple changes

 

i have the aluminum one. i haven't changed it in.. a year? two? don't even remember. no problem here. :dunno:

 

:werd:

 

Alright. Then a little Al2O3.2H2O it is. :goodjob:

 

plastic one? for a small price just upgrade to the aluminum one.
