Any one getting a consistant 40 to 45 or so with their Aveo?
Consistant 20 to 25 here... ;) 8) But then again, I don't hypermill, only time traffic lights sometimes, accellerate quickly... keep my RPM high, and stay around 70 MPH on the highway... So I know that I could be getting higher, but there's more to life than MPG, if you know what I mean. ;)
Depends. If Canadian mpg, I regularly get 40-42. If US mpg it"s somewhere between 32-34.Quote:

23????????? you might just as well drive a Dodge Ram hemi!!! Jk :mrgreen:
i drive too hard, i have always pushed my car, going 75 or so through the backroads and hitting 105 on the highway will bring down your milage, i dont care about MPG though, i just want drive hard lol
Best mpg: 37.7. No fluke either because I got 425 miles out of that tank. All highway, 65mph.
Worst mpg: 26.7 (aside from first 1000 miles when the engine was being broken in).
In total, avg of 32 mpg, 40k continuous miles recorded.
i personally feel my gas conservation comes from the choice of car more than how i drive it.Quote:

i don't know how you people feel you have enough time in your lives to let things small things take that much longer.
Not being in a hurry is kind of nice. Most americans have no clue what i'm saying because they create this false "I have to be somewhere in 3 minutes " type of life style.... I look at it as consuming less and saving on my wallet... Plus i'm pretty relaxed when I arrive at my destination and most of the time early. It's the people that are the other way that don't allow time to drive that have road rage issues. Don't understand driving fast in a economy size car....Like driving 80 in a prius because you think it will get good enough mpg what's the point ? I guess it takes all kinds and thats what makes the world go around... I'll keep doing my thing.
Fighting irish do you have an auto or a stick trans? What year is your Aveo?
2007 manual trans sedan.Quote:

people are confused when i fly past thier cars that are worth 5 times more than mine :PQuote:

The last 2x's I filled up it was at 37mpg. My daily travel is 150 miles and 70% of that is at 65-70mph on Interstate @ 70MPH the little red beast is running at 3400rpm. Actually I thought that was extremely high until I read some of the other comments on this thread :shock: 2009 aveo5 manual transmission.
thats pretty good... I just got 38.6 on last avg. working for 40 though. with my 06 with man. I try to keep the rpm's down under 3000 on freeway. Usually at 2500 which is 55 mph in my Aveo.
I averaged 35-38 when I had my Aveo, my record trying for tops MPG was in the 50 mpg range, but no way I could keep those driving habits up, it's documented somewhere around one of these aveo sites
I wanted to hear that cause i'm on amission to get in the 40's and then upper 40's if I can.I am going to try to get the Aveo to give up some great mileage!

I would do just that if I was single but then again if I was single I would be driving a gen 1 insight. I have newer tires on now 80k mile warranty. I didn't even know about the LRR tires at the time. Mine are aired to 44 psi max sidewall. What was the biggest thing for you getting the big numbers? Coasting in n with engine off is one I try to do as much as possible. I am working on trying to get a scan guage to help me see when i'm wasting fuel. Anymore advice on it? What do you drive now?
LRR tires, wouldn't you loose some performance with those? i.e. snow/wet handling? From what I understand the better performing the tire, the less life/FE you get out of it...

In comparison to what though? Obviously a summer performance tire is going to have the best dry grip, but has worse wet & snow grip. Every tire is a compromise is some way unfortunately. For everyday driving I bet most newer LRRs out there are as good as most season tires. I think older LRRs used to have worse traction, but the technology has really come a long way in the past 5-10 years. Plus, many OEM tires are already LRRs to get the car's EPA rating higher. I don't think the newer LRR tires are really not much of a compromise, but they probably are a little bit. So, for my daily drivers, they get LRR tires, but for my fun cars, they get sticky tires. :)Quote:

What do you mean by underdrive pulley? I keep my car below 3k at all costs.... I saw that you got the Suzuki on another post ,cool, bummer it's the auto but It will be cool to see what avg.you can get from it? Any mods planned for it right away? Do you drive alot of highway for city? Hope it's hwy for the sake of the tranny.I was wondering if an exhaust system would help me much as far as mpg..? I don't care about the hp part. What you think? Would swapping the muffler to something like a flowmaster would it help mpg's much? I was planning on trying to get the best I can with it all stock but if I can have additional help with the mpg..I'll take it!
A high flow muffler won't help. It only needs to flow lots of air when you are using lots of horsepower (more horsepower used, more exhaust air to flow). Since you keep it under 3k rpms, you're never really even using close to peak horsepower. And, while the stock muffler may be restrictive at peak horsepower, it certainly isn't at 3k rpm.
I had thought of this very thing after posting. Well saving money then. :D
Under drive pulley reduces rotation mass thus the engine has less work to do, thus saving gas and increasing power. A full exhaust can help because it let's the engine again run more effeciently (but also means you'll want to floor it more for the cool sound, thus negating the mpg gained,) but one can also go too big with exhaust and lose low end power, with exhaust it's always a fine balance
As for my Forenza...yes it will mostly be highway, 36miles one way to work. As for mods for it, I've got a K&N already on the way and I think I may go with a catback exhaust with a Borla muffler.
The actual best effiency for an engine is the horsepower/torque crossover point (usually around 5280rpm) but that's also not practical for most driving
Good points there... It was time to change the tires on my HHR so I got some Continental ExtremeContact DWS (Dry/Wet/Snow traction) which are 100% as good as the reviews say they are... I'm not sure if they're LRR tires (didn't find that info on the tirerack website, but then again, I didn't look that hard), but I did see the improvement in the MPG numbers over the last 6k miles that I had the tires on it...Quote:

Of course, that doesn't mean you want to *cruise* at that RPM if you have the option of going to a higher gear - only that if you need POWAH!, that's the most efficient range to generate it. If MPG is your goal, you should still cruise at the lowest practical RPM. But if you need power to climb a long hill (or accelerating), trying to keep the engine as close as possible to that 250 island would yield best results.
All your driving tips are good.
And what's that in RPM in our cars??
From all the BSFC charts I've seen it always seems to center roughly around 2500 rpm. Unfortunately, its VERY rare to find BSFC charts for engines.
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?
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)
i have a 05 man 5 speed getting around 31-33
is that mostly highway or mixed? what gas are you running? describe your driving habits...Quote:

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.Quote:

Can anyone tell me the solution to it?
