Left at 0-dark-thirty this morning headed for Austin. Drove the same route I've driven many times.
It usually takes a full tank of gas for the round trip. Topped off the tank this morning and headed out.
The tC is usually right on 1/2 tank when I arrive at my destination. This time I arrived with 5/8 of a tank.
Got home with 1/4 of a tank of gas.
Same rush hour traffic in Austin.
A/C was running the whole way.
Eco mode turned off as usual.
Same lead foot. (speaking of which, I blew past a DPS officer running radar doing 75 in 65 zone and was sure I was going to get tagged. He was either asleep, or looking for bigger fish)
No recent oil change or air filter change.
No change in tire pressure.
I certainly haven't lost any weight.
pretty strange. I'm stumped.
