Well got the VDO oil gauge working last night. first drive 80 mph about twenty minutes on I-85 it stabilized at 220f, but i managed to take out my dash lights, so will trouble shoot that tonight. will drive the car a few weeks to get a good idea on the average temp then put in the Microlon. more to follow.

Mechanic probably gets a cut of the profits of any oil treatment sale. That is the way it works in the car dealerships and such. They call it it up selling.
