I ran a few Champion oil filters in my airplane, and switched to Tempest recently. Now that I've switched, I notice my oil pressure takes a few seconds to come off the peg after starting. The Champion would be rising instantly after start, but the Tempest takes a few seconds.
I also notice I seem to have more oil in the sump, after the first flight post-oil-change (i.e. the Tempest filter doesn't seem to be holding as much oil)
So, I'm wondering if perhaps the Tempests lack the check valve that supposedly keeps the oil in the filter.
I haven't yet removed one of the Tempests from service so I can't say for sure.
It would be nice if it's not full of oil like the Champions...
Anyone else noticed this? Think it's any better for your engine to get that oil pressure up a few seconds faster?
