Question that's worng witg my TSX?

I just got my TSX 4 days ago..i only got close to 200KM when half tank of gas is gone(first tank of gas).. The car still in break-in. i keep it under 3000 rpm and little over 70kmph. so is this is normal or some thing went wrong?..

The gas meter is non linear. It always seems like it drops to half in 100 miles, then slows down afterwards.

At this early stage, I would say it's normal. You should be getting between 22 and 28 mpg average. Obvioulsy break in and driving style will affect this.

I don't pay as much attention to the gauge as I do to the Range estimation from the navigation system's trip info screen. (Dunno if you have navigation.) Range + miles this tank = total estimated range for this tank. (That screen also shows your mileage, but it's a little optimistic, IMO.)

On a full tank, it starts off with an optimistic range estimate of 496 miles, which would correspond to a little over 29 MPG (assuming the tank tops up to 17 gallons exactly). As I drive, it adjusts to be more realistic and ends up around a more conservative 380-420 miles. I usually end up with tank mileage of 26-28 MPG.

I have not observed better mileage with break-in (my car is now at 7596 miles). My best tank was my second, at something like 30.5 MPG.

Other factors that will affect mileage: Weight load (How many passengers? How much do they weigh? How much stuff are you hauling?), how aggressively you accelerate (Do you get up to 40-55 MPH each block on an expressway, only to stop at the next sign/light? Is even your freeway driving punctuated with braking because you were tailgating?), and city vs. freeway.

Actually, in the Functional Setup Menu (Map-Menu-Cancel for like 5 seconds -> Functional Setup -> Trip Information) it'll show you the actual sampled fuel in your gas tank (down to 1.1 gal) and actually show you the miles the car estimates until empty. The one displeyd on Trip info for 0 miles left is actually when you'd hit about 1.5 gal left in your tank.

also....don't forget....it's winter. some gas stations will put additivies into the mixture. that may cause some of the lower mpg that people are getting.

Does anybody find the gas gauge a bit useless? Like Lung said, it's non-linear, also, it doesn't have 1/4 marks, it's not straight up and down, and it doesn't quite sweep 180 degrees, which makes even guesstimating the 1/4 or 1/8 points hard. And I think the gas-low light comes on too soon.

Kinda strange considering the rest of the instruments are well laid out.

Ditto, 5 months and 5,000 miles and I have the same findings. I set one tripmeter everytime I fill the tank and drive on miles, not the gauge.

Me too. I will believe the gauge if I have around 300 miles on the odo. Then it's about time to fill.
