Like the title says, I have a really low oil pressure reading on my defi BF gauge. I have the sensor mounted in the head where many others from this board have mounted it. So now for the issue, it reads as low as 1 or 0 at idle after driving for 20-30 minutes. The stock oil pressure warning light has never indicated a problem with low oil pressure. As rpm increases, oil pressure increases. So i find it hard to believe I have a bad oil pump.
My car currently has 15,400 miles on the ODO. Is it possible the sending unit for the defi gauge is causing the problem? Any test I could do to find the source of the problem would be of great help!

Mine gets to about 0.5 to 0.6 bar when warmed up. Not all the way to 0 though. Peace.

 

1 bar would be 14 some odd PSI, so you're fine.

 

It's the imperial BF gauge, which reads in psi, I should have mentioned that earlier.
