[QUOTE=shaeery;4565946]My New Corolla Xli is not going more than 475km in full tank. As now weather is good and AC did not use and still it is 460-475km/tank.
I have driven about 1400km.
Someone suggest me to change its oil.
Aoa, I have been using same car since 23rd September. First tank was filled at 230km mark and it showed me range of 608km ... I refilled it at 730km before reserve light came on (so 500km driven) and in 45L tank was filled to the top. So it gave me an average of 11.5 km/L on first full tank.
Second tank gave me 590km till my fuel guage needle was exactly on E. I refilled it again on 1325km (5km short of full 600). This time it required 48L to reach the cap.
My average meter is now stuck at 12km/L and bro I drive way too fast. I change first three gears at 4000rpm on average. Sometimes I take my car to 6500rpm but average never went below 12km/L.
In my opinion, u should clean your air intake, that might be lowering your fuel economy. I mostly drive alone, with AC on till now. So in full tank, I drive it to 600km mark in city driving, i must say.
