DEF shelf life
I have read that DEF has a definite shelf life, and I've heard figures of around 6 months. Given that most of us don't use our motorhomes in the winter, or at least like in my case, only on relatively...

Holstein, I also wonder how accurate the built-in fuel mileage computer will compare to my pencil to paper calculations. I'm also writing down the mileage and fuel added at every stop.
One long 780 mile traveling segment (2 days) through Texas with a 15-20 mph headwind going about 70 (wanted to stretch the Elegant Ladies legs), we were averaging 5.8 mpg. Our toad weighs 3,500 lbs. I feel that once the engine is broken in, our total average over time will be between 6.5-6.8.
I'll keep an eye on the DEF usage. Since I only filled it once, I'm not sure how accurate the needle is and if it was filled to the brim when I picked the coach up. We started off with almost 3,200 miles at delivery and now have about 6,800. The coach had to be driven from Canada (bus shell) to the converter (N. Chicago) then to the painter (in Indiana), back to N. Chicago, then to Stuart, FL, for delivery. All the fluids were changed and the chassis serviced before delivery.
Prevost said I can go 35,000 miles between oil changes or once a year. I stopped in Ft. Worth Texas at the Prevost service center to have a defective fog light replaced under warranty (the reflective material inside the bezel was discolored).
Safe travels,
MM.
