Seems like the engine oil weight would be a 4th data point for sure.

80C ..that's a very 'par normal' temp ....close to 176 F ..something
like that, the thermostat I run in summer.

so there's your data point there ..'normally warmed up' .
The oil will be around 80C most of the time unless it's very cold , or
it hasn't been running long ..

Does it even mention oil weight for this test.
I looked for the official oil pressure testing thing in Bentley and
didn't find it.
what page is it on please.

Therefore, for the purpose of determining engine health, which I though we were discussing, you must use 3 data points or, again, you're guessing. And if a guess is close enough then you're ok.
