regen and mpg

I was driving in west Texas last weekend. I left a campground and the next town was 40 miles away. The fuel miles remaining indicator said the truck had 70 miles until empty. About half way there the mileage until empty started dropping rapidly. It got down to zero miles remaining just as I pulled into the fuel station.

Whew! That was close.

Yeah, don't ever trust the DTE numbers. Once that gauge starts getting near the 1/4 mark, just get it filled. Though I am guilty of doing what you did...once. I had my 5th wheel hooked up to my '08 F-250. With the long bed, it had a 40 gallon fuel tank. I pulled in to the station with the gauge hovering over E. I put 40.2 gallons of diesel in the tank. Talking about an Oh Crap moment!

Glad you made it!

To restore your mpg in an emergency you could probably pull over and shut it down mid-regen. I don't think another regen will start until the DPF gets back up to 100%.

That's a great idea. I hope you're right. I'll try it next time. However, I hope there won't be a "next time."

Can't always do it, but I try to fill up at one half tank or slightly less. A couple times I let the tank get low and finishing a fill up requires stopping and starting again as different stations have different cut off amounts. I like the 48 gallon tank on the road though.

Mathematically it just doesn't make sense but the bottom half is smaller than the top half.

This is what I call "The half-tank phenomenon". Once you hit the half-tank mark on the gauge, the needle goes down much quicker than it did from full to half. It's a truth!!

Around here the pay-at-the-pump limits me to $100 and won't let you swipe the card and go again. I always have to go inside and pre-authorize the pump for an amount over what I estimate it to hold if I think it's going to be over $100. Seems to be the same no matter which station I use.
