You probably already know that the cold weather will reduce your Avg Mpg. My 10 mile A road commute drops from 38-40mpg to 33-34 Mpg at this time of year depending on the air temperature. It shoukd pick up from the Service Mpg once you drive it normally.

The weather has got noticeably colder (where I am in the UK at least) in the last couple of weeks, and it's also been wet and windy which hurts fuel economy.
