Does anyone know/understand the logic of the intermediate marks in this instrument?
I'm going nuts trying to understand which numbers are supposed to be associated to each intermediate mark...
Mind, I know that it's probably not worth bother about them because the gauge isn't so accurate anyway.
But I was looking at the performance report of my Fountain, and it shows 140/180/195 respectively when Cold/Hot/WOT.
Now, I'm wondering where the tester could see the 180 for instance. Not to mention the 195...!?!

See the number at the bottom of the gauge call it and as them why the do that, it not just the oil temp gauge its all their gauges.

thats so they dont have to be so accurate

Well, not in my dashboard, where only the water and oil temperature have intermediate marks whose logic is hard to understand (if any!).
The other ones are:
Fuel: empty to full, main marks at empty/half/full and intermediate marks at each quarter;
Water pressure: 0 to 35, main marks at each 5 increment, with 5 intermediate marks between them;
Oil pressure: 0 to 80, main marks at each 20 increment, with 1 intermediate mark between them;
Voltage: 8 to 18, main marks at each 2 increment, with 1 intermediate mark between them;
Speedo and RPM are also marked very clearly.
Mind, I'm not saying they're all accurate, but at least they're consistent....

I agree and I sell them!!

The point of gauges on any machinery isnt to be so accurate as it is to indicate an issue. If these were precision gauges they would cost about 2 - 3 times as much and be dampened.

I agree about the scales, they could be a lot better.
