MPH vs MPG
I bought a 2022 Chevy 3500 6.6L Duramax Turbo Diesel and wanted to check the fuel economy for both towing and not towing. The numbers you'll see DO NOT include regen periods where the engine is burni...

However, I checked those figures with eight stops at the pump (1400 miles in total), manually calculated the MPG and found there was good agreement between the two (within 1% on average).
So......eight stops at the pumps over 1,400 miles averages out to about 175 miles.....I’m so confused.
Here is a "maybe" as to why,
175 miles between stops when towing, could be explained as the driver needing a break, or having a small fuel tank and fueling up at half a tank just to be safe.
On my gasser, it has a drinking problem (7 - 8 mpg) with a small tank. I would not push 175 miles between fillups as a routine as I'm selective on which gas station I can fit in and get out of. With my mileage, I would start getting a low fuel warning at about 1/4" tank which is about 175 miles. I always want a reserve of fuel in case I get stuck out on the road or I can't fit in the nearest gas station, I can go to the next, etc. Between 100 - 125 miles (about a 1/2 tank mark) I'm stopping for a top-off on days when I tow over 200 miles in a day. We all camp and tow different, and all are OK.
The OP is getting a whole lot more miles per gallon than my gasser. Their MPG is not quite double mine, but close. I suspect their tolerance zone, is at the 175 area either for a truck reason or their need, or a pet's need, to get out and walk around.
Just a thought.
