My 2014 Accord EX L suddenly had its MPG go from about 30 to about 26 - Dealer did a injector cleaning etc - no problems were found - problem still exists - Does anyone suspect or have a CVT transmission that caused gas mileage to plummet? Car has 66000 miles. ---

Winter blend gas and winter driving will drop gas mileage. Has anyone checked the egr valve? ---

> [@SteveCBT](#): > > Winter blend gas and winter driving will drop gas mileage +1 If the OP lives in a region where winter temperatures plummet, that is the likely cause of the problem, as ALL gasoline engines will yield lower MPGs in winter weather. That being said, I really hope that the OP isn’t warming-up the engine for more than… maybe… 30 seconds before driving. Extended warm-ups are not necessary and will only lead to an even greater drop in gas mileage than simply driving in winter weather would produce. ---

I have a 2017 Accord EX-L with the same drive train as yours. With summer blend gas, I get about 38 mpg on the highway with no traffic jams. With winter gas, I get about 34. Off the highway, I get less than 30 mpg with winter gas. If you live in an area that gives cold enough, you are seeing the effects of winter gas. ---

Also tire inflation plays a small role in MPG. Lower temps = lower tire pressure = more rolling resistance. It’s especially noticeable here where there are days in the 80s and 90s F and also nights where it is in the teens or more below zero F. Your 2017 car has a TPMS but I am not sure if that would activate if all the tires drop approximately equally. ---

> [@shanonia](#): > > Also tire inflation plays a small role in MPG. Lower temps = lower tire pressure = more rolling resistance +1 When the ambient temp in my area dropped into the low 20s last week, I checked my tire pressure, and–sure enough–it had dropped by 4 psi, all around. So despite the fact that I had done my regular tire pressure check only a few weeks previously, I had to pull out my tire inflator and inflate my tires back to their “normal” level. When was the last time that the OP got _up close and personal_ with his tires, and checked their pressure with a hand-held gauge? ---

Agree, normal drop in cold weather. Just make sure your tires are inflated to the sticker psi when cold.
