Hi Raju,

We guess you’re talking about the second-generation Avensis, made from 2003-2009. That means you’ve either got a 1.8 VVT-i or a 2.0 VVT-i. In which case, these officially do combined economy of 39.2mpg and 34.9mpg respectively, which translate as 7.2 litres/100km (1.8 VVT-i) and 8.1 litres/100km (2.0 VVT-i).
