I am now getting better gas mileage in my 34 y.o. VW bus which weighs about 500 lbs. more than my Kia.
Seriously 4-6 on the highway at 100? My best was 6.9L @ 100kms Its usually 7.2.I just did the "factory SRI" mod at 13000km and even driving like a bat outta hell i have only gotten as low as 12.3L/100km @ 90/10 city/highway. The best I have gotten since the mod was about 8.5L/100km 50/50 city/highway. Pre-mod I was doing 10.5worst/9.0best city driving and 8.5worst/6.2best highway.
Keep in mind that winter gas is different from summer gas and cold air is more dense so more fuel is required to achieve desired fuel ratios.
That said, I have a really hard time taming my foot now that it sounds so good. I have noticed that when under strict supervision (wife in passenger seat) my instant economy runs down around 4-6L/100km on the highway... but even supervision cant avoid the "need" to pass a car or two.
I also notice that I get my best fuel economy on either ESSO(89 oct) or Petro Canada(91 oct) fuels.
Sorry about the ramble. My friends are sick of hearing me talk about my car so I tend to have a lot to say when I get the opportunity...
The average on my Forte's meter today is 11.6 L/100 km.Im averaging 13L/100kms, and I rarely put my foot down. Very disappointed. I would race my honda all day and still get better fuel economy
How broken in is your car? Mine has less than 1000 miles and it seems to suck up gas like crazy, though it seems better with each fill up (yep all 3 of them).
I had them detail my car last week and they must of left it on with the heat blasting so this tank will probably be poor.
