What is that number?

12.5 + 6.25 = 18.75

>>17645880
6.25?

>>17645856
12.5

>>17645884
First line is 12.5
Therefore, between big lines is an interval of 12.5
Therefore, between small lines is an interval of 12.5 divided by 2, or 6.25

>>17645856
710

>>17645884
Well between the 0 and the 25 there is a big marker, which is the halfway point so 12.5 and then inbetween the big marker and the 25 there is a small marker which is the halfway point of that, whose value is 6.25 so in total it is 18.75. Or you can calculate it by multiplying 25 by 3/4.

a number less than 25 PSI

>>17645896
first line is 0, just like the last line is 100

if the first line was 12.5, everything else is out of scale.

>>17645880
>>17645904
I'm pretty sure the first line is 0

>>17645856
I'd have to go with 12.5. Needle probably sits all the way at zero because it's difficult, mechanically, to get it linear at pressures close to zero.

>>17645913
Simple analogue pressure gauges work linearly, look at the distance the needle travels between 0 and 25 the way you say it and look at the rest of the lines.

>>17645931
>linearly
There is increasing distance between the big lines as it goes up the scale. I don't know how this thing is designed, but linearity isn't always cheap and easy.

>>17645931
kek, i see what you're saying now. why the fuck would they make it that way? with lopsided scaling? that'd drive me nuts

>>17645942
Might right, I dunno anymore.

This is the gauge when cars on "ON" mode guess that's 0

>>17645966
Then my point being 18.75 goes completely moot.

I guess the needle compensates for the oil exerting some pressure for just existing, which is apparently around 12.5 psi.

>>17645949
Because it's a general reference.if you're in that range you're dangerously low anyway. The oil pressure is constantly changing so no point in a precise measurement. Your car dulls out the reading so you don't see it all over the place when you drive.

>12.5 psi increments
That is lame. They could've used 10 psi increments and had a more usable gauge.

>>17645966
why the fuck does the needle fall so low when it has no power
