Ridiculous??? The active mpg gauge has been a staple of BMW gauge clusters for 20 years or more, so don't knock it. Why that engine needs an oil temp gauge is really beyond me. Mpg gauge is far more fitting.
Vdo makes transducers that take the place of the oil drain plug, then you can just wire a gauge in wherever. Start with that.
