Kind a big deal for me today-I'm going for a 950 mile tank. I've had a couple previous 900 mile tanks, and I'm pushing it as far as I can tolerate. I really don't want to run out of fuel especially since I have my wifes car keys and my car keys with me at the same time by accident. Sure hope I make it to the fuel station! After I see how much fuel I still have in the tank, I may go for 1000 miles on the next one
