Here's my story of the day... I pulled in to my favorite Gulf station, and right away I knew there was trouble. As I mentioned earlier in this thread, one of their two diesel pumps was crashed-into and removed about two months ago, and they still haven't replaced it yet. So today I saw an 18-wheeler filling up on the small-nozzle side
of the one remaining diesel pump, and on the other side was a diesel pickup. Parked behind the pickup was another commercial truck, but at a glance I didn't know if it was diesel or gas.
So I asked the attendant "Do you have a lot of people waiting for diesel?" He said yes, and just at that moment
another diesel truck pulled in, and when the attendant saw it he said "
Oh my God..." That was my clue to get out of there and find another source of diesel fuel.
Even though I had been driving for the past 15 miles or so with the fuel gauge pinned at empty, I knew from experience that meant I still had half a gallon left in the tank, so rather than join an angry mob of truck drivers waiting for diesel at the Gulf station, I backtracked through city streets to a Shell station I passed on the highway about 2 miles back. Both stations offer ULSD "Premium Diesel", but Gulf is usually 10 cents/gallon lower than Shell, but in this case Shell won out due to their no-wait diesel pumps.
Total cost to me was $45.00, for 18.008 gallons of fuel in an 18.5-gallon tank.
I often wish I had the same setup as the "Black Gold" Datsun 240Z, which had
two fuel gauges -- the second one showed only the lowest 1/4th of the tank, in 1/10th of a gallon increments.
