Oil pressure readings

[DallasTahoe]

Just curious as to what my gauge should be reading, I need a baseline so I can get a jump on it if need be, after my engine is warmed up mine reads about 20 at idle while in gear, and about 40 on the highway doing 60 or so @17-1800rpm. I think it's low but I need some help to be sure. Thanks

i am at 273k and about the same roughly just a little higher with revving. factory minimums are 6psi, 18psi and 24psi at1k, 2k, 4k respectively. but if they drop another 5 psi i would work on a high volume pump or re-bearing the engine along with a normal pump.

Ok thanks Sunlit that puts my mind at ease!

What oil are you using and what oil do you recommend Sunlit?

i got 235k on mine i had to change the oil intake o ring cuz mine would lose all oil pressure at idle until the engine warmed up

i also use 10w30 instead of 5w30

i use mobil one synthetic 5w-30 for now.

I'm using cast roll Getz high mileage synthetic blend 10w-40. I replaced the oil pressure sending unit, now it shows I'm getting 40-45psi at cruising speed and about 15 at idle in gear
