As in, it's a normal gauge? And the unmarked notches are 12.5, 25, 37.5, etc?
Cause some random oil change mechanic at TA was insisting that it's not. He was saying the unmarked notches go like 20-40-45, or some nonsense like that. Was he on some good stuff?
Or was he somehow right, and I'm the ignorant trucker?
A Cascadia oil pressure gauge is linear, right?

And no one has ever mentioned the markers being pre set, the readings not being equivalent to what the hashes are.PermanentTourist Thanks this. -

On another note... I recall from our previous conversation that you also drive Cascadias...
Here's a question that's got me overthinking the oil pressure gauge to begin with: I just went from regular to semi synthetic 10w30 on my truck. Now my oil pressure at normal cruise of 65 or so is sitting lower than before, at around 38-40. It seems uncomfortably low, especially with brand new fresh oil?Dave_in_AZ Thanks this. -

I would be changing mechanics if one said this to me.Dave_in_AZ Thanks this. -
I think this truck has the 10 - 30 synthetic in it, it's new to me. Start up cold right now is around 60.
I'll see where it's at when it warms up.
