Hi All,

I just got me a C240 2005.
Have changed the oil & tune up at a local merc workshop with zero defects on the diagnos.
My q is.. fuel consumption is 14 MPG which is not quite good refer to some research. Anything i should consider to change to
solve this?
And I’m planning to change my rims & tyres, for a sporty but not too low look what size of
rims & tyres should i take?

Thanks in advance
