Fumoto Oil Drain Valve
 

Greetings,

I just bought a Fumoto oil drain valve for my '98 S70, it comes with a seal that looks like it is meant to take the place of the aluminum crush washer. The seal seems to be made of a green sort of gasket material. If any of you guys have installed one of these valves, did you use this green seal in place of the aluminum washer, or in addition to it?

Thanks!
