Well I made it back to Fort Hood fine. Drove 12 hrs yesterday and 8 hrs today. Here are some stats:
Average mpg was 13, not too bad considering i was going 70 mph half the time. The legs that i was going 70 mph were esp bad. I was getting only about 11 mpg. Weird thing was when i was going through the mountains of NC and TN, averaging 55mph, i was getting the best mpg at 13-15 range. Gas prices averaged about 3.29. Arkansas was especially high up in the $3.49 range. Spent a total of $307.03 on gas which is better than what I had predicted (thought it was gonna be over 400). And drove a total of 1224 miles.
I actually got 205 miles out of one tank in TN. That's cuz I didn't see a gas station for about 20 miles. I was worried there for a bit. Luckily I didn't have to experience what you did Tokkie.
Now time to get my tires rotated and oil changed.
