yes and no..
oil temp at first tracks coolant temp.
it's going to be at least that warm.
then....the more you drive, and the hotter things are ...oil temp goes
up and up gradually ..
so in terms of not exceeding redline oil temp ...a gauge is useful..
otherwise ..
you know when it's normal and when it's extra hot ..
like when ambient temps are high ....under a lot of load , that's when
oil temps can get dangerously high without much in the way of an oil cooler.
otherwise ..you know when it's well warmed up but likley not 'that hot.'
oil pressure at an oil temp of 'par warmed up' is what of interest.
