      Rpms? (~3k @ 65-75 on highway, is 25 mpg normal?)

      Hi I'm new to site just got question I just bought a 09 Aveo5 with 50k miles on it when I'm driving a 65-75 it's running around 3-3300 rpms And getting around 25 mpg on highway is this normal? Thank you Rodney

      The rpms sound about right for that speed, but 25 mpg seems very low. Is this a recent occurance, or have you always gotten 25 mpg?

      For reference:
      My 2010 Aveo5 would average about 38mpg with the cruise at 65mph...but that was after the car was warmed up, without the AC on, and the tires at 40psi. I could easily get down to mid 20's when I got up around 80mph.

      My car also had a flat spot in the mid range but it was not as pronounced as you describe.
      Sorry GM, the Turbo Sonic was priced too close to the Focus ST. I gots me a Ford.

      If i stayed that slow (i'm not hypermiler material) i get in the low 30s for mpg. I have an 09 too, which my understanding the 10+ has a slightly taller 5th gear So your really only talking 1-2 mpg difference between years, but its mostly in technique.

      What kind of gas do you use? I have found that if i use bp, shell or sunoco I get much better mileage that using sheetz or getgo (both local discount gas). I have noticed almost a 4-5 mpg difference running the cheap stuff.

      are your strictly going by some sort of gauge? or are you calculating at fill ups/mileage?
