The owners manual is very clear that oil pressure should be about 30 psi on a Ferguson 30.
Mine was starting reading 30 psi at start-up but dropping to about 20 psi when fully warmed up.
I changed the oil and filter and used 15W40 oil, because that's what I had. I figured it would have higher pressure when hot, but I was wrong. Now it reads 40 psi at start-up and drops to almost 15 psi when fully warmed up. I'm not noticing any other problems except the reading on the gauge.
So what sort of problem do I have? And what is going to fail first if I keep running it like this?
