When I pulled into the diesel pump this afternoon...

1. The Drivers Information Center said that I had 57 miles to go before empty.

2. The "low fuel warning" alert had come on 20 miles earlier.

3. The owners manual says it's a 34 gallon tank.

4. It took 32 gallons plus a pint of Opti-Lube XPD.

5. I'm averaging 17.5 mpg.

That's cutting it wayyy too close for comfort.. specially in the wintertime.
