Top mpg

[byron84]

I have found that in 3rd, 4th and 5th gear, when not trying to accelerate, having the lowest possible RPM is best. At any point if you need to accelerate at all, then you're better off revving at the right RPM to spend less time accelerating. Even if you are only revving at 1200rpm in 3rd, if you start accelerating, you won't move much and you are wasting a LOT of gas. You're better off being in 2nd gear, getting up to speed and then coasting.

I also found that in 1st and 2nd gear, it's virtually impossible to get good mileage no matter what you do. Best to get through those two gears and coast in 3rd and up as much as possible.

I find that for the highway though, just under 3000rpm is usually the sweet spot. Much lower and you're going too slow, much higher and you're wasting too much gas. Sometimes I'll go faster cause the situation permits good mileage despite the speed (cars in front of you, slight downward incline etc)

Whats wrong with going a little slow.... and whats slow? 50?

[thehunterooo]

slow for me is anything under 75-80 on the highway

Yeah - "slow" is relative to the road and/or the traffic and/or the driver's opinion .

But on the freeways where byron84 drives, the traffic probably flows at around 110 - 120 km/h (68 - 75 mph). Posted limit is 100 km/h (62 mph).

Last night me, the wife, and the kids went for a drive in our HHR (It's a 2.4 automatic), and I figured I'd try to take it careful and try to get some good MPG out of it, it was mostly highway driving with some coasting down hills in neutral (not sure if that's bad for the automatic transmission, I'm just used to doing it with manual), and we got up to 34.4 MPG... not too bad for a car that size with two adults and two kids with their bulky car seats and a small stroller in the back. Of course stopping at drive-through at the end of the trip brought it down to 31-32, but I'm still kind of impressed by those numbers out of a family car like that.

Our 2.3 tubro CX-7 AWD would get 22 something on a good day on the freeway.. and it got as bad as 15-16 mpg around the city. So the HHR is actually an improvement as far as the MPG goes, and almost as everything else too as far as options go: remote start, heated leather, roof rack, all chromed out from the factory, running boards, 2.4 instead of 2.2... I'm happy with the buy (got it in Jan)

is that mostly highway or mixed? what gas are you running? describe your driving habits...

I get like 27mpg in my 08 sedan aveo, i cant seem to get any higher, but then again im speeding as well. Slow for me on the high way is like 75ish.

And they say the mileage drops significantly at speeds over 50 or so... Someone posted a chart a little while ago, but I can't find it.

i dont have road rage or anything but i just like driving fast and getting to my destination, i hate car rides some times. Also i dont understand why i cant get better MPG because i have driven in the lower end of my RPM's and no luck, even my dad has given it a try at the good MPG, i think its just not possible. Can anyone tell me the solution to it?
