oil pressure gauge, what is the normal pressure Options

[Needles]

my oil engine light came out whethever i puss the gas a little bit .... when im on gear and running, and goes away the second i leave the gas completly
if i put just a bit when accelerating , it will do it but sometimes flash.

i dont lose and burn any oil
my dipstick have correct oil in it,
i did change oil and did put the excxat amount on it,
so it dont need more oil

why my oil light came out , ?

Low pressure = high flow = oil is hot and thin. OR low. Keep that in mind. My pressure on a cold start will usually rise to about 40 and then start dropping if I'm low on oil.

High pressure = low flow = oil is cold and thick.

Think of pressure like the difference between drinking a Coke through a straw, and then drinking pancake syrup with the same straw. Thicker stuff requires more pressure to move.

Those pics don't look like the 7AFE, which is what I have. Cold start in hot weather gets me 60 psi, cold weather 65-70 psi and takes forever to reach that. Idle pressure at operating temp is 15-20 psi. Cruising pressure at 3,000 RPM at operating temp is around 35 psi. It usually drops a few psi with the A/C running. I assume this has something to do with changes in vacuum/PCV system when the A/C is on. From what I've read, and this is just a "universal" standard, is you want 10 psi for every 1,000 rpms the engine is turning. Obviously though, at operating temp you won't see that. I only hit around 40-45 psi at 6,000 RPM at operating temp.

So your pressure sounds fine
