On oil filters I will always remember Mike Smith from East Coast Rover telling me only use a landy Rover oil filter. He was working on my ‘95 D90 and ‘93 LWB Rangie at the time. Feel sure they have it made for them yet always have followed his advice. That was in 1996.It has a wix oil filter which I believe is a good quality one. I will change the oil and filter when I get back from a trip next week. My D1 with 300tdi builds oil pressure almost immediately regardless of temperature. I’m pretty sure I have a Mahle filter on it.
I think GG’s oil filter comment was more so diesel oriented. But from what tests I’ve seen, WIX is pretty solid. That’s what I use on everything.It has a wix oil filter which I believe is a good quality one. I will change the oil and filter when I get back from a trip next week.

This is what I’ve been thinking. What oil filer are you running?What about oil filter? Oil filter has a flapper valve that retains oil in all engine upper ducts, in order to get oil pressure quickly after start. I suggest to do 2 tests: after this long time with no pressure, to stop engine immediately and after 5 minutes to test it again. If time is shorter, then You can do second test: to change filter (always the best branded quality), and test again. I hope this is the only issue. I suffered this trouble once with my TDI, and it was oil filter

It’s a goofy size. I can’t remember. I’ve used an adapter that goes on in place of the oil filter before. It was a great tool that a friend had. If you find one post it up, I would buy one.Anyone have a recommendation on an oil pressure gauge with the correct fitting OR the size of the oil pressure sender fitting so I put something together? The lighter oil sped up (5seconds 30s weather) but now its a bit noisier on initial startup. once warmed up its good though. May as well get some more data though.
I used a sandwich adapter to hook up a mechanical gauge. Haven't plumbed one permanently.It’s a goofy size. I can’t remember. I’ve used an adapter that goes on in place of the oil filter before. It was a great tool that a friend had. If you find one post it up, I would buy one.
Similar behavior as OP and others, I've been running the black Mahle OEMs. Maybe it's worth trying something different...This is what I’ve been thinking. What oil filer are you running?
You can usually see the check valve. It’s worth a shot to at least to inspect it. If the filter allows oil to leak down it would act like your describingSimilar behavior as OP and others, I've been running the black Mahle OEMs. Maybe it's worth trying something different...

Reading through most of this. The idea of the oil being to heavy really depends on how far downstream the sensor is from the pump, If the pump has to push the oil through no small amount of the engine to get to the sensor then yes, it would cause low pressure readings for a while. But, as an engine ages and tolerances become greater usually increasing weight helps keep oil pressure up. One could try like a 5w-40 to address both issues. That said one should remember the higher the viscosity the less actual oil there is in that bottle.In my head, a lighter weight oil like 5w would build less pressure than 15w, a heavier weight. Could be 100% wrong so let us know.
So this is a new engine to you? A conclusion one could come to is the previous owner did put a high weight oil in to mask low pressure readings. I'd change the oil right now with what the manual calls for and see what happens.The previous owner changed the oil about 1000 miles ago. It is still quite clean. I’m wondering if he put 20w50 oil in it and maybe changing to 10w30 would help?
