I wanted to confirm my earlier mpg report with a trip I made yesterday.
I filled up right-up to the gas cap before leaving.
Did 287.6 miles, mostly all on speed control at 65mph on a relatively flat highway. (no city driving). No special driving technique was use to maximize mpg, just normal driving.
When I came back, I filled-up again a the same pump, at the same service station, at the same level.
result : 29.92mpg
With 390K on the clock, I think it is not too shabby.
