How many miles per gallon is this (4 cyl) car supposed to get?

I just bought a used 2000 Sonata and filled the tank with highest octane available at Esso. I've gone through a 1/4 tank in what seems to me to be a very short time without driving very much.

On some cars the gas tank level inicators are not real accurate. They go down faster the less gas there is in the tank. Is the gas gauge on the Sonata known to be a little finicky in any way?

I've had the car inspected twice for service recommendations and have done all the recommended things. Are there ways to tune this car up to get better mileage?

US specs (4cyl/auto) are 20mpg city and 27 highway (23
combined). Of course, this isn't REAL driving, only dyno. And the faux mix (city/hwy) may not mirror your usage. Another thought:
my old Ford with the AOD trans quit going into fourth gear. Never paid much attention until the fuel bill jumped. Checked the milage and was getting around eleven to the gallon. Among other things, the US$2000 for a rebuilt tranny made the decision to get a new Santa Fe MUCH easier. =;-)

I don't think it calls for the higher octane.

You need to go through several tankfulls, keep a total mileage record and fuel usage, before you can get a good handle on the mpg. For instance, I've got 28,815 miles on my '02 Santa Fe and put 1346.6 US gallons in the tank. Doesn't matter if the tank didn't get to the tippy top on any given day. The multiple fillups give me an accurate (IMHO) figure of 21.4 mpg.

Yeah it turns out to have about the same milage as the 1987 Buick Century I traded in on it. I thought the new car would be much better but i guess my old beast was pretty good in the 1st place.
 
I have the 2.5L v6 and it gets 22-25 in normal driving.. just fill up the tank, hit the trip odometer, then see how many gallons it takes to fil lthe car up next time. Miles you drove/gallons = MPG
