What kind of mileage do you get?

I've got a 2004 Elantra GLS and the EPA mileage rating for the 4-speed automatic is, I believe, 24MPG. The car started around 19.5-20, and I was somewhat surprised. I figured I'd get at least 22.

I took off the factory air filter and put a cone filter on, and along with the addition of a Tornado and the subtraction of the muffler, I'm up to averaging between 21-24MPG. Finally up to the EPA city mileage estimate.

Any others here tune for mileage? That's the main reason I tuned the car any.

I just picked up a new 05 GLS with AT; my first tank was 29.4 mpg

[edit: After three tanks, it has slipped to about 27 mpg overall. This tank, though, seems to be doing much better: almost 200 miles and still have half a tank.]

I drove Nashville - Columbus a week and a half ago in my '04 GLS Auto. Had 414 miles on that tank when I filled up and only put in 11.3 gallons. Works out to be 36.6 or so.

I have an '01 GT w/auto transmission. On average between city and highway driving I'm getting 30.7. On strictly highway, its been up to about 36 mpg.

97 Elantra 1.8 GLS Manual tranny with 100 000 miles. With 2 adults and 2 kids, doing steady 80 mph on the highway with the air conditioning on and the trunk full of luggage I get 24 mpg. If I drive alone, same speed, no AC, no luggage I get 27 mpg. I have new spark plugs and new spark plug wires. My injection system has recently been cleaned.

I have a '95 Elantra. I get about 30-35 miles to the gallon. This is a combined estimate of city and highway. It has a 12 gallon tank and I get about 420 miles to the tank.

I had a '95 Elantra 5 speed that averaged right at or just below 30 mpg. I know have an '03 Elantra 5 speed that gets between 30-32 mpg. Both cars are driven primarily on the highway with a little city driving.
