Hi all, I noticed the last few times i drove my weekly 400 km highway trip my honda seems like it is getting less gas milage than i used to get. It still runs exactly the same and i didn't do anything different to my car. Should i be checking anything on my car? The trip used to cost about $35 and now it is around $40. (price of gas was the same) The temperature outside is getting colder, would that make much difference or if it was raining of moisture in the air etc? Also would driving speed 5km-10km more per hour make that much difference? Thanks.

I did, i could not find any, only poor gas milage on a new car.

 

type "milage" in the search. don't be too specific. I tried it; it works.
