Well , here it is winter . Not running the A/C .

Our little Sonic has 24,000 + miles . Filled it up last Saturday . We have run several errands , 100% in town . The guess-o-meter on the dash is showing 29.5 + MPG .

Only modification is a self installed after market cruse control .

Last summer it got 23 - 24 MPG with the A/C being used much of the time .

I am happy .

God bless
