I maintain my car diligently.
In December 2009 (one month ago) I had the timing belt replaced, a new radiator installed, and the valve cover gasket replaced.
My mileage on a subsequent trip decreased dramatically from 34 MPG to 28 MPG.
The garage that performed the work is honest and reliable.
Any thoughts on the cause?
