2010 Honda Accord EX 6 Cyl 3.5L
What could be causing my 2010 Honda Accord to drop 50% of the miles per gallon?
My 2010 Honda Accord has dropped by approximately 50% in the miles per gallon it once had. I have been advised by two different sources the following solutions;
First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
