439.7 miles on a tank. Good? Bad?

Your 20s won't help, but they wouldn't be doing nearly that much damage. Check your air filter first (it's easiest), then do your basic oil/plugs/wires. Check fuel filter as well. Any of those or a combination of those would contribute to really bad mileage.
Also, your gauge could be bad. How many gallons are you putting in when you top off wit half of a tank?

I actually had taking a road trip form Huntsville, AL to south Georgia. Went 366.3 miles on a full tank of gas, cruised at 70-80 mph. No cruise control. Loaded down. Filled up with 16.2 gallons. Thats the best it has ever gotten, also running with windows cracked and NO A/C.

On the trip back from AZ when I bought my car, I made it from Meteor Crater, AZ to Las Vegas, NM on one tank. I filled up in Las Vegas, did the math, and had gotten 26.75 mpg with the cruise at 80 and the A/C on for a good deal of time. Since then I've not driven the car enough to even check mileage haha.

My 1991 Limited does about 550-600km or so on a tank, majority freeway driving to work and 2 hour crawl on the way home. I travel about 550kms/week in this car, I fill up once a week on 98RON.
My trip speed Monday to Friday is about 70km/h for the first half and about 110-120km/h for the rest, and on Sunday is about 80km/h for about half an hour.
Make sure your car is in good condition and it'll run like a champ.

SC tank is 20 gallons, my sc3 gets about that but 2jz dosent get better fuel economy. There's a mile long thread on 2gs forum on fuel economy, its not even broken down to i6vsv8 they are about the same. Our Gs400 gets about 400 miles to 17.5gallons is when the light has been on for about 20 miles or so i know the tank in GS is 18.5 gallons, thats mixed driving i'm sure i can get about 420-440 out of it if i drive very easy and 450+ on the highway.
