blackbeast ss Posted December 23, 2008 Report Share Posted December 23, 2008 yeah my truck does the same thing it drops a couple mpgs in the winter time,i think it has something to do with the cold weather Quote Link to comment Share on other sites More sharing options...

F1SSS Posted December 23, 2008 Report Share Posted December 23, 2008 (edited) I drive mine like an old lady in the winter the heat wrecks my mpg. In summer I dont use the A/C, so its a noticable difference, even the power seems a little more responsive imo with no heat or A/C on. In the winter, to keep power loss to a minumin I just put my heat on 70 at the lowest setting, and keep my heated seats on. I like the cold though.....

juriha Posted December 23, 2008 Report Share Posted December 23, 2008 I've seen my MPG drop pretty good since the winter has sprung, but I am guessing its because I start it and let it run for a good 10 minutes before I drive, that will def. effect it, by sitting and burning all that petrol.

Fireman31 Posted December 23, 2008 Report Share Posted December 23, 2008 Many factors can effect gas mileage, tire pressure, idle time, driving style(i.e. heavy foot), weather, etc. A dirty air/fuel filter, worn spark plugs/wires, plus a dirty MAF and TB can also contribute. This time of year, most gasoline has a 10% ethanol mix which can account for a loss in MPG too...... Quote Link to comment Share on other sites More sharing options...
ssspringer Posted December 23, 2008 Report Share Posted December 23, 2008 I'm seeing the same thing...I thinks it's the gas formulation! Quote Link to comment Share on other sites More sharing options...
cwest94 Posted December 23, 2008 Report Share Posted December 23, 2008 Wow, I dont think I've ever gotten over 13MPG before and I drive like an old lady. The MPG's on my daily driver has gone way down with me using the remote start on it every day. Quote Link to comment Share on other sites More sharing options...
