No more fuel

Today the only trip I had to make was to work and back, a combined distance of 26miles. There was three light showing on the digital fuel gauge before I set off, and three lights showing when I got to work 13 miles later. I parked on a slope with the right side of my car lower than the left and when I returned to it 8 hours later I push the engine start button and hear the starter motor for a little too long. I thought I didn’t have enough fuel but the engine started eventually. Half way into my trip home and the fuel gauge showed empty, and then flicked to one light a mile before I returned home, and then to empty as I parked up. It seems the fuel gauge is as temperamental as the Type-R was.
