    122 deg F is 50 deg C.  Your oil is never going to be colder than that aside from startup, so
they didin't bother.

    The VW oil temp sensor covers 100deg C.  From 50 to 150.  Normal running temp is 100, dot on.

    I think in the case of your bro-in-law's m5, whoever told him that was REALLY saying "don't
rev until the engine warms up".  Your engine is warmed (at least oil) by the time it hits 50.
Which is when your oil temp indicator starts working.  Ta daaaaa.

The oil temp on the MFA doesn't display until it hits 122 deg F.  I don't
know what's magic about 122, but my bro-in-law's '91 M5 said to not rev
above 4k rpm until the oil hit 122.  So I always keep the oil temp on until
it starts to register and don't crank it until it's warmed up.  Cold oil
can equal insufficient protection.
