Too good to be true!

Well, either I have a problem or Volvo Jesus blessed my truck last night. I just ran over 300 miles and the fuel gauge on my 08 880 haven't moved a bit. I can used the old odometer/calculator method to make my deadhead home run, but what do you guys think will be the easiest/most likely problem to check first?

Of course, if I'm really getting infinite fuel mileage, I'm not going to complain.

 

Amen to that. I'm not going to complain too much, I have been very lucky on this truck (so far.). It's only spent a few unplanned hours, and less than $1500 in the shop in the 3 years I've had it.

 

Saint Volvo apparently fixed it, either that or I was burning 5 gallons a mile the last 20 miles into home. I checked it with a stick when I pulled into home, so apparently something broke loose. Probably a leaf or stick from the pump at the T/A. I will keep an eye on it for awhile.

 

I checked it again today, and it was fine. I guess that was it. I thought maybe Volvo had solved gas mileage with tiny nuclear reactors or something.
