29/36, as stated on the pressure label. Good thing I checked the spare. Apparently previous owner didn't; it had 2lbs in it. I aired it up to 60.

Second tank, 17mpg from ~ 105mi city, ~50 fwy.
I need to check the air filter, and track the fuel trims.

I have driven 17573 miles in just over 3 years. I am at 20.66 Avg MPG. Keep your tires at proper pressures and stay up on the maintenance. I think you are in the ballpark. How spirited do you drive? I have had tanks that measured low at +/-16 and high at just over 23. Safe travels.

I also had this question, and found this thread:

A lot of perspective from forum members.

Just getting on the freeway, the reserve light came on. After a 35 mile round trip, the needle was half way between Empty and Positively. 14 gal fill with 276 on the Odo = 19.8MPG mixed driving, more freeway this tank.
