106 quicksilver burns a lot urgent help

friends, have a nice day everyone, i have 2000 model quicksilver, i just bought my car but it seems like it burns 100 tl gasoline in the city between 180/200 km do you think it is normal Injector cleaner spilled did not benefit the tank again

IF OXYGEN SENSOR FAILURE IS MOUNTED, IT CONNECTS TO THE COMPUTER.

I have it connected to the computer, it does not give any error

CAN YOU COMPRISE WITH USE CAN YOU COMPRESSE ON THE ROAD ???

Unfortunately, the same numbers appear when I go to 2nd gear and go even at a fixed speed. I don't think it will be absolutely relevant to use because I use it so much

If you constantly go in 2nd gear, of course it burns much, the more gears grow, the lower the consumption.

all the way I want to explain is not going to go in the 2nd gear :)

Are the rims wide?

I have my own original rim exhaust, but I always use off. No performance filter.

I DID NOT SOLVE ..

It means that if there is a lot of traffic burning, I think it's normal.

I think it looks like 195.45.15 rims, I have 106 qs in the city, 40 krş room stop and get up, even though I do not install the fln , the room does not have air filter, there is no exhaust . I suggest you need to pay attention to it took at least bi fuel to get the same number several times from different stations bi try my skin.
