I'm not a mechanical engineer and so not an expert (just have an engineering background).
I know that the oil is cooled in that way and not 'electronically'. With respect, that has nothing to do with my question. I want to know if it's possible that an electrical component or thermostat is malfunctioning (possibly just by cutting in too soon, or reading a temp wrongly?) on some cars and the oil temp is in fact within limits, if a little on the high side. If this were the case, it would be a simple fix.
Also (and this is a bit of a side issue), how do you know
that the oil temp guage is reading 'moderately accurately'? Without wishing to appear rude, isn't this an act of faith on your part, or do you have proof?
