I noticed a few OBD II based products out there that give real-time data readouts to the driver. You just plug them into your obd II port. Why couldn't somebody make an Oil Life Indicator like on the Honda's or the GM's, just figure out their algorithyms....etc. It could plug into your OBDII port, monitor you fuel used, engine temp, rpm's, speed, trip distance, ambient temp, and factor in whether you're using dino/synth and then spit out a Oil Life % Left etc. That's something I would buy if you could mess with the variables after doing UOA's. I bet this wouldn't be too hard to do for a techie.... Anybody have any thoughts on this?
