I have a 97 and have noted that, although the tank capacity is listed at 21.1 gallons or so, when the gas gauge reads "empty" and I fill it up it only takes 17 gallons. This is pissing me off because I have a 24 hour road trip coming up and I'd prefer to minimize the number of times I stop for gas. But I don't want to run out, especially in Arkansas

. Nearly 20% in reserve seems pretty ridiculous, but maybe that's what we're dealing with here.
