Cornfuzzled yet again...
True. Mechanic told my grandpa the same thing back in 87 when he bought his 4runner
That was 22 yrs ago!!!May have been true then, but today almost all quality filters have the anti-drain valve....
What unclestripey is talking about is the "anti dranback valve" that is in the filter. Pretty much every oil filter sold now has them.
Why yes, yes they do!
