Many probably have not seen this being discussed deep in the diesel thread, so here it goes.
As most informed people do, they monitor their maintenance schedule based on hours not miles. Unfortunately not everything has a hour meter, but if you do, you are in luck. This helps a lot when looking at vehicles to purchase to see if they were truly 'highway' driven.
If you do have a hour meter, simply take your mileage and divide it by the hours. This will give you an average MPH. Obviously the higher the better. If you want to see what your ideal mileage should be, take your hours and multiple by 33.
33 MPH is a great bench mark that was set by a big truck manufacturer back in the day.
My 05 GTP which I knew was a highway car when I got it @136k, has a average mph of 42. My miles are 196k and 4600 hours.
Let's take hours and multiple by 33. It gives me a total mileage of 153k. Which is awesome, this car really is all highway.
I had a truck in today with 55k miles and 5500 hours. That gives us an average mph of 10 mph. You bet your ass the egr system is clogged the fuck up from idling and doing no work.
This makes 3 in a row for same company. If I was a fleet manager I would be having their asses and installing idle shut down timers. All 3 of these repairs have costed them roughly $15k total
Let's see what the actual life is. 5500 X 33 = 181k...
