Purolator & Wix will not warranty standpipe oil filters for /6 but Baldwin will.

No, they didn't; see here.

Fair points on all sides in this discussion. I'm not about to criticise anyone's decision on whether to worry about filter warranties—they might or might not be the same decisions I'd make; everyone has to decide for themself what they're comfortable doing, and there's no right or wrong answer here. It shows just how rational and consistent we humans aren't that we're perfectly happy to drive an old car, severely unsafe by today's standards…but too risk-averse to use a heavy-duty filter because the maker won't warrant it in an off-label application.

We also see rabbits in clouds, a face in the moon, Jesus in our grilled-cheese sandwiches from time to time, and luck in our favourite numbers. None of it's really there, but…MonkeyOS 1.1b3 is a very quirky operating system! View attachment 1715770887

Thanks for settin me straight Dan....as usual. In that linked to post you left out an option. This one:

OR you can use a 90* filter adapter like this:
NO chance of oil drain back. I also like that I have room to run a 2 quart filter.
