My Gas Milage
#31
Well I don't know how you all are getting that kinda milage....when I am on the interstate cruising at 75 my DIC is showing 22-23MPG.... 2.4L 5-speed with cruse control on all the way ran 350 miles today and best I saw was 24.2 for a few minutes. My HHR has 50K on the clock....tune-up time?
I did have plugs replaced at 60K as I don't trust 100K spark plug change. I have to say that at 60 K the plugs still looked good.

Cruising at 35mph going 2000 RPM in 5th is worse that doing 35 mph in 3rd at 3600 RPM

Simply having it in 5th isn't enough. You have to find that sweet spot where the flywheel and resistance on the trans is as equal as possible so the engine doesn't work very hard. That could be as high as 4000 RPMs depending on the situation.

Easy to lug a motor down at low speeds, even up to 45....I experiment with "I" in town and see a noticable difference(auto). Find that 'no-load' rpm range and you will see better in town milage. If you hit the gas and it groans its too low....if you barley touch the gas and it scoots your there.
