Jay,
Is this the Fram PH-43? I've been using Fram's forever, it seems like. Not only
do they match the color of the B, Consumer Reports rated their Wearguard filter
as number one, a notch and a half above others.
But your report, plus stray comments on the Buick mailing list, hmm...
Normally I change the oil at 3,000 miles or whenever it takes longer than a few
seconds to build pressure, which seems to be start happening about 2,500 miles.
Maybe the Fram is crapping out?
I also am curious as to what the SOL regard as the best filter.
