Hi Warden, My 300D gets about 21 MPG in the City. This is simple city driving, so the milage is not very good. Sometimes less.
I do make a point about taking it out for long drives to keep the engine happy.
Freeway gets about 25 MPG on basic drives.
On long drives like San Francisco to San Diego on HWY 5
I get better than 25 MPG. Probably the same as your max.

The local shops farm out to this shop.
