Sonata V6 Gas Mileage

I am getting 22MPG city and 27 MPG highway on my 2000 V6 Sonata. I do
not hot rod the car.

I see other drivers "going for broke" between red lights and I am
certain that their mileage must be less. Often I can look ahead and
see that the next light is not going to change in time for me to make
the green. I will let off of the accelerator as I approach this
light. No need to keep pouring on the fuel at the expense of the
brakes.

Sometimes the driver behind me will switch lanes and go roaring past
me, braking hard for the light and we will both be side-by-side
waiting for the green. That driver will also be likely to be buying
new tires before I do also.

Another tip for getting good as mileage is to keep the tires properly
inflated. Low air pressure equals a liitle bit less gas mileage.

You are very luckily. I don't hotrod either but have only been getting
between 15.45 to 18.75 on a 2003 with a 2.7 engine.

 

Have you taken it inot the dealer and have him check the error codes?
Perhaps a MAF sensor is malfuntioning.

All hyundai's gas mileage is overrated by 10/15 % Not happy with mine
either.. No response from Hyundai " dont care once its totled!!!! "

 

rubbish.
i have no trouble getting better than the claimed figures with my
accent. with the air conditioner only on for about 25% of the time
i've been using 6.6 litres per 100km. i've seen it get as good as a
touch over 5 litres per 100km when on a very rare drive without using
the air conditioner.

My latest gas mileage check was last Sunday. I filled the gas the gas
tank and went then drove 104 miles mostly freeway driving at about
70-75 MPH. When I got home I refilled the gas tank and it took 3.7
gallons. My handy dandy calculator says that comes to a hair over 28
MPG.

This is for a V6 engine and best of all, the Hyundai is one of the few
V6s thats only requires regular rather than premium gas.

The reason it uses standard 87 Octane gas is that Hyundai makes the
car run pig-rich and retards the timing like mad at higher RPM to keep
the engine from exploding with its 10.0:1 compression ratio. I'd be
much happier if they offered a retuned ECU (that won't void the
warranty) for 89 or 91 Octane gas. They could lean the car out to
13.0:1 (from about 10.5:1). You'd end up with an extra 8-10 HP and
another 1-3 MPG and there'd still be a safety margin to keep you from
running lean and killing your engine.

 

My wife has a 2003 Sonata with a 2.7 l V-6 with about 10000 miles. Her
mileage with a mix of roughly 70% interstate and 30% non-interstate varies
between 22 and 27. Like you she is a cautious driver. Based on the other
comments I have seen this is typical mileage for this model and engine.
