timothyf Posted January 10, 2017 Share Posted January 10, 2017 Hi, my FFH mpg has declined this winter from its usual 36 mpg to 31-32mpg. No idiot lights illuminated. Any ideas what may be causing the lower MPG? The car has 120k mileage. Thanks, Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 11, 2017 Share Posted January 11, 2017 Aside from winter gas (common to lose 5-10%)? What is the maintenance history on your FFH? When was the standard battery last changed? Link to comment Share on other sites More sharing options...
drolds1 Posted January 11, 2017 Share Posted January 11, 2017 There are numerous discussions on this topic in the specific FFH forum. For example. Please use the 'Search' function before posting a quetion so that we don't have multiple threads for the same topic. This thread is now closed. Any further discussion shoule be posted in that forum. 1 Link to comment Share on other sites More sharing options...
