. My best tank (summer time) was 420 miles (676 km) so I'd say you have a combination of issues contributing to the sudden drop in fuel economy. Good luck & keep all of us posted
So, your summer is 6.5 L/100km (that's how it is calculated here in Canada... don't ask why, but it's the opposite of the US!)
And your winter is 7.1 L/100km
The original flyer that came with the car ("EnerGuide") mentionned something along those lines... 7 L/100km on highway, and somewhere in the 9 L/100km in the city.
Right now, my topped-up tank is about to run out (the light went on this morning) and I am at 440km... I don't know what is the quantity of fuel remaining in the tank when the low fuel light goes on, but let's assume 5 liters? Right now, I might be good for another 40 km before I run out of gas (I never wait too long to refuel after the light is ON... and last fall I was doing at least 525km at the point the light would go on).
So 480km would give me 10.4L/100km, 60% HWAY, 40% CITY, which is not super good, but not extra bad.
I don't know WHEN the petrol companies stop putting winter additives in the gas, but I would think it should be ALREADY done as we speak... It's spring and we don't get below 0 degrees C.
I'll go fill-up my car with good gas and I will add the Lucas Fuel System Cleaner into the tank, and we'll see how it goes after this tank.
I also cleaned my MAF sensor. Mine was exactly like VIBENVY's MAF. Mine seem really clean, but I cleaned it anyway.
In 3-4 weeks, if I don't see improvements in the fuel comsumption, I will have to further investigate the cause... it REALLY bugs me! Last summer, the light goes on and I am at 525km. Now, the light goes on and I am at 440km. I am missing somewhere between 75 and 85km per tanks.
Thanks
