2005 Accord - Sudden significant decline in miles/gal
 

Greetings,

My 2005 Accord EX (2.4L) did average of 28 miles per gallon for two years (since I got it in November 2004 until about begining of December 2006). I drive the same highway every day, same speeds (average of 75), same distance every day, went through the same seasons twice (summer/winter) in the same place. Nothing, and I mean absolutely nothing has changed in my driving habbits.

Then, sometime in begining of December 2006, all of a sudden I noticed a decline of about 20% in my fuel consumption...from average 28 to average 22.

Any one experienced this before? Any idea what could it be?

Thanks.

Thanks for the link.

Is it possible that indeed something went caput, such as a valve, or
something? I mean, tire pressure or things like that cannot cause a 20%
decrease overnight.
The car is still under warranty.

Re: 2005 Accord - Sudden significant decline in miles/gal
 

My first suspicions would be (1) unusual cold, which can
reduce efficiency a lot, like 10% lower fuel mileage; (2)
ethanol or whatever loaded gasoline, required in some parts
of the country; and (3) tire pressure drop; tire pressure
can change radically within a couple of weeks and will
easily reduce mileage by 5-10%. One should check the
pressure every two weeks.

How many miles are on this car? Are you following the
maintenance schedule for plugs, wires, and other ignition
parts? Admittedly it's a very young car by years...

Yes it's possible something went kaput, but I'd expect a
check engine light for the "kaput" item on such a recent
model. E.g. if the oxygen sensor was defective, you should
get a "code" indicating it's failing, and this would first
be indicated by the check engine light.
