[robert421960]

its 95 and very humid here in se ky today
i just put a new oil sending unit on my tractor but im showing really low oil pressure
is it cause of thin oil maybe?

i have 368 hrs on the tractor
any good ideas tonight?
thanks

Wrong oil. Drain and refill with 15W40, pressure will go back up

What was the pressure showing on the gauge prior to replacing the sending unit (transducer)? That's what Ken was asking.

sorry i did not understand that
i had sparatic (im sure that is not spelled right) readings before changing senderfrom high to low to nothing
now it reads barely in the blue then when warm its in the red
im gonna change my oil in a couple days

I use straight 30 weight in all my farm diesel tractors. Ken Sweet

is that thicker than 10 w 30?
