I filled my tank the other day in an effort to see how many miles I could get on a full tank (50%hwy/50%city). At the same time, I got curious to know how much fuel was left in reserve after the warning light came on. The manual only said a "small reserve" is left. I was at 254 miles when the fuel light came on. I immediately filled up. The pump stopped at 16.5 gallons. Since the tank is a 19.4 gallon tank, and if my math is correct, then about 3 gallons is left after fuel light warning, correct? It seems like a lot, since they said a "small reserve". Can anyone out there confirm? It's not that I like to drive around on fumes, I'm just interested in knowing, especially if i'm out in the middle of nowhere. It would be nice to know exactly when I have to get out and hitch.
