I'm beginning to think the Shell station on 76th went back to the blended fuel. In this last tank of gas in my Ranger, I'm seeing a good 30 miles difference. The gas gauge is about a needle with below the 1/4 mark and I usually see 315-320 miles at this point. Right now I've driven 295. I'll find out for sure Friday when I stop to fill up.

I've driven no different between the last two fill ups, no unnecessary idling or anything our of the ordinary.
