When it's hot (190 degrees) my gauge reads about 5 psi at low idle and about 15 psi at full throttle. Guess this is normal for a well worn gas engine? Thanks

A D15 should have the FULL FLOW PH8 type filter ??   15 psi is a little low, but like you said, its OLD and thats what you get. As long as you have FLOW it should be OK....What viscosity is the oil ?  New filter ?
Like them all, but love the "B"s.

Thanks Steve, it's time for a oil change. Can't remember if I used 10W30 or 15W40 rotella. I have it written in my maintenance log out in the shop. Yeah I'm thinking it's full flow.

We run AGCO filters on our tractors, our D15 series II runs 3/4 on the normal range of the factory gauge but we rebuilt the engine last year. Not sure what psi range that is though. Assuming maybe a 30 psi gauge?

When I first acquired my D-15 Series I, it also ran a little low on oil pressure.  However, When I changed the oil with high quality 10w30 and installed the AGCO oil filter, all was back to NORMAL.  With pointer on the R.  Good Luck!
