series 60 mileage and speed

[DOSZORROS]

I have lived and drive in the northwest, mostly. Hauling 50,000 lbs. plus up over tall mountains can use a bit more fuel.

I have a brother that travels with a diesel pickup and a fifth wheel and he is meticulous about logging fuel and mileage. He claims the brand of diesel fuel can effect mileage 10% on a regular basis. He is very selective about the brand of fuel he uses. There is one brand of diesel that he will not buy given any choice.

Just something else to mix the pot.

I have learned the secret to great mileage on my 2000 LXi is to reset the ProDriver just before heading down a very long grade. Then I get in the 9s steadily decreasing down to the 6.5 I get everywhere else ;-)

I wonder how coach total odo mileage factors in. Mine has 46K and may not be broken in yet.

Whenever it needs fuel, I fill it up. Besides the novelty of knowing, I don't typically have the luxury of biding my time to gain fuel mileage. Currently the $100 difference is easily made up in the extra time spent in the office. Maybe someday!
