You know I think I have been pretty patient so far - I bought my '07 Accent GS Sportback in summer with only47km on it. I liked the car, took it for a spin and basically bought it the next day.

Gas consumption is listed on Hyundai's website as 8.5 & 5.9 litres per 100km city/highway respectively. - This is the listing for Automatics which is what I have.

The car comes with a 45 litre fueltank. The tank registers as empty (at least the low fuel light illuminates) at approx 35 - 36 litres leaving about 10 litresreserve. Quite a big reserve I might add, but nonetheless, better than being too small.

Anyways, so from the time the tank gets down to "E" on the gauge and the low fuel lights up, I take a peek at the odometer and it is anywhere from 395 to 410km. Usually the lower of the two.

Now I know that there is a break-in period, and even the Hyundai techs said 8000 - 10000km before the engine starts to show better mileage, but then when I had my first oil change done at 5200km the guy said I wont start to see the improved mileage until 6000km.

Doing the math, taking even the higher mileage per tank of 410km, divide that into the 35 litres of consumption = 11.7km per litre or about 8.54L per 100km

So it falls just outside the specs for city driving, but the consumption is looking like I only drive in the city - and I dont - In fact, 30 of my 38 km commute each day is on the highway and I am certainly not an agressive driver.

I dont expect to see 5.9L per 100km but I certainly do not expect to see 8.5 as my average either.

Wondering what other people have experienced with theirnew Accent? When did you see the mileageimprove - or have you?

Northboy.

 

i have noticed similar issues with my car, i tend to get worse MPG then is advertised no matter what speed im going. i did notice that it matters where i get my gas, some stations, like shell, just seem to have better gas then others.

 

I think you are right about Shell - However I have only really tried Esso and Shell since I love the Speedpass / Easy Pay system. Shell seems to have ok gas, but what I did notice is that no matter what grade of fuel you buy, you end up getting the same mileage. Shell has occasionally been out of regular so they offer super at the same price. Absolutely no difference in performance and mileage that I can see.

Cheers,

Same problem with my 2001 Accent 1.5 CDX Automatic. I have converted the engine to LPG and now getting 60 miles for the price of one gallon of petrol on the motor way. In the city its 40 miles. I think the automatics do poorly with fuel consumption.

 

Do you have Ethanol or "oxygenated" fuel for winter where you live?

Where I am, they use oxygenated fuel in the winter months - it cuts about 10% from your expected efficiency. It's supposed to reduce pollutants by 10%, but you have to consume 10% more of it to go the same distance, so it's a silly thing to do -- though I bet someone is making money from this scheme.

 

They're making a lot of money off of it. I've heard from a lot of people and have tested the theory myself that cars that do not specifically say they take "flex fuel" (only some 2006's and newer I think) run horrible with ethanol. It made my mom's chevy act really weird, it just drove really funny and had less power. It made my Saturn go from 33 mpg to 28 mpg (The Saturn and Chevy are 4 cyl). And worst of all, my friend's mustang, a 6 cyl (now I hate mustangs anyways but), would not even start with ethanol gas until the idle and something else were adjusted. I've heard many others saying the ethanol clogs up your fuel lines very easily and can actually hurt your engine over time. I pay more to go to gas stations that don't use ethanol right now but Florida is trying to pass a bill that requires all gas stations to use ethanol. If that ever happens, the economy will really crash here because everyone's cars are going to die and no one will be able to get to work! Okay so I know that might be an exaggeration...
