I have never reset my Trip 2 since the car was new. So now I also can track total time that the car has been switched ON.
I write the total miles and total time on every gas receipt. When I have absolutely nothing better to do I plan to put the numbers into Excel (yeah, OCD, I know) , and then chart out total cost/mile and total cost/hour. Total cost = every dollar I have spent on the car. It would blow your mind to see what those two rates are.
So, as long as cars are a big expense, we may as well drive around nice, fun cars, that turn heads, starting with our own!
I reset one trip with each tank (or at the end of a long multi-tank trip) and leave the other, never resetting it. It reset itself, apparently at about 10k miles.
