Post Your Gas Mileage

Thought this would be a good thread to start, and sticky it. It's always nice to compare what everyone is getting in the fuel economy area.

Just checked with the last fill with just under 3000 miles on the odo, and having the Mobil 1 5W20 in for 2000 miles, the last average was 28.3 mpg, all city driving.

Will be hitting 30,000 miles this week! Have been running Mob 1 5w-20 since the 1st oil change. I see around 31 mpg on average. I make several trips a week that are all highway and around 100 - 300 miles each way. When making the all highway mile trips, I average 34-35 mpg.

I pour a few ounces of Lucas fuel treatment in the tank every 4th or 5th fill up and change the oil every 5,000 miles instead the factory recommended 7,500 miles.

With almost 4000 miles on the odo, the latest tank of gas produced 31.3 mpg with all city driving. So we are now beating the EPA 25 mpg city rating by 6.3 mpg. In spite of what some people might say, I think the Mobil 1 is what is helping that along.

Just passed 36,500 miles on my 2010 EX Eco...

5w30 changed every 3,000-4,000 miles at the dealer, got new tires and put nitrogen in the tires, mixed freeway/city driving.

Lifetime average: 32.1 mpg
Last tank: 30.2
Best tank: 38.6
Worst tank: 28.1

If I don't run the a/c and stick to the freeway under 70 mph, I can get 36-37 mpg, but California is kinda hot right now so it's back down to 30.2 mpg.

whats up everyone! just purchased my Forte Koup today, its a 2012 SX model, its the 2.4L w/6 speed manual transmission. i drove it about 100 miles today and im averaging 31.2 mpg in the city and almost 36 on the highway! very happy with my decision to purchase the forte, I work at the manufacturing plant in west point, Ga where we manufacture the Kia Serento, Hyundai Sante Fe, and soon the Kia Optima. I can tell everyone that Kia is doing everything in there power to be #1 in global quality so I can assure everyone that your decision to purchase a Kia forte was a very wise choice!

Do you still have the Kia phone book air filter. Change it out for a good freeflow type (K&N). Disconect battery for about 5 min. to reset ECU.. Take car out for a good hard drive ..Mileage should improve...

What kind of driver you are has an effect on mpg, as well as how much the A/C is used, tire pressure, idling time, climate, and type of gas. The kind of mpg you're getting is either a combination of what I mentioned, or a mechanical issue. I'd have the dealer run some tests to see if anything shows that could be causing it.

It is 20percent highway and 80% city driving.
I use regular gas. Tried BP, Shell and Mobil. Almost same. I never used AC, and almost all the time, my ECO green light was on. I don't think there is a mechanical issue, because it is a new car. I called KIA customer service and they said wait until I reach 7000 miles, and it will be OK. But you guys are having good MPG with same miles I have.

Cars can have issues right out of the box. You could have a bad sensor, bad EGR Valve, Bad PCV, bad intake manifold, or corrupt ECM software. It could even be dragging brakes.

If you live in a cold climate, the cold will make any of those things cause even worse results. And don't forget, running the defroster also runs the A/C to dry the air. That knocks 20% off your mpg. I recently had a recall on my Forester that was to reprogram my ECM with new software to correct an emission issue. The engine is now running better, the tranny is shifting better, and the result was a 1 mpg improvement in fuel economy.

You need to complain to your dealer long and hard.

My car is the 2.0L sedan w/ 6-speed automatic (100% stock) and I average 29.9 miles per gallon (according to Fuelly.com, which I use to track my MPG) and my sedan has just over 9,000 miles. I never drive on the highway, but the majority of my "city" driving is at 40-45 mph with few stops for traffic lights so it's quiet efficient. My worst tank was exactly 26 MPG (the city rating of the car) which was earned by parking practice for my driver's license test. All in all, I'm very pleased at how effortless it is to attain 30 MPG in this car.

I purchased my 2012 Forte 5 EX last Saturday with a full tank and 37 miles on it. I topped it off on the way home to make sure it was full. It now has 345 miles and I just filled it up for the first time. 60% hwy & 40% city with the AC on constantly.
Dividing the gallons into the miles, I averaged only 24.3 mpg. :(
I was really expecting more, since my '05 Toyota Rav4 AWD was averaging almost 23 on the same gas.
Does this sound normal for this car with only 345 miles? Will it really get better as the motor breaks in?

I'm a little worried because we only got this car to replace the Rav4 because we wanted better mpg. Gas on Maui is around $4.44 per gallon right now, but only $4.19 at Costco. Even at $4.19, I need better than 25mpg (even with AC) to make me not regret getting this car. It is nice though....

Put 1000 miles on it and then switch to a good synthetic oil. Once you have 10,000 on the odo the mpg will rise. My wife typically gets around 32 mpg around town.

After making a 54 mile non stop run to breakfast cruise set at 65 in a 55mph setting I don't see this Forte ever doing 28mpg with the cruise set at 80mph. My 2007 2.4L 175hp 4 speed auto Saturn ION-3 sedan does 34 set at 80 on flat ground runs.. I'll report the outcome either way.

You have to break in the engine. Most brand new cars will do that. RTFM
