Contact
www.bobstheoilguy.com and inquire but I have a hard time believing you can put 50 weight
oil through any descent modern filter medium at any temperature without a bunch of it being bypassed either by the "Filter Bypass" or the
oil pump "Pressure Relief Valve??
Either way most of the
oil does not go through the filter in a single pass.
At any rate you DO NOT need any thread sealant on the filter's threads!!
