Ok so that's the salt is out here now I have put the vx away. Winter plans for it. The cx that I always got 42-43 mpg worst tank ever was 38-39. Well I got a tank that was 34. Ok no panic I had to commutes to work in blizzardlike conditions. I also was stuck in an accident for 45 min with the engine idling. Hey its like 20deg and I gotta work out in it all day. So I thought that was it well next tank same thing 34-35. I checked tire pressure I checked for dragging brakes I'm going to do cap and rotor as they are flakey looking. I've just never tracked every tank like I have been lately. It just seems like a large drop in winter I know 2-3 wouldn't surprise me but 7-8 seems high.
Look at my sig line for average summer and winter mileage. The difference is mostly caused by temperature.
Winter 2011-2012 was warm, so average mileage only dropped to 30.1 MPG. Summer 2014 was not as warm as previous summers, but the addition of the vacuum gauge helped increase summer mileage to 38.2 MPG.
wHILE i DO EXPERIENCE SOME WINTER DROP OFF, mine tends to be the gas mix because, I live in areas that dont have extreme low temps and bad weather.
Since the Q45 had automatic air/heat, I tend to run a/c all the time in the summer and very little in the winter. So I get some trade off there. (my summer mpg isnt as high as it could be)

My driver car is always garages also Well I went to put new cap and rotor on car while test driving she's dead. No spark. Man I love having to get all the neighbors to help get the car uphill 300 foot driveway covered in ice and snow. And I can't push it into the garage. I beg to differ with the list in regards to cold tires more resistance. Hot tires sticks sticky well sticky. Witch rolls better a sticky ball or a hard ball? But now I got a dead cx.... Trying to find test specs for the dizzy igniter and coil.
