Compared to what? I can pretty much guarantee there are exhausts out there that will get better gas mileage. And then there is always Unobtanium.

compared to the 49 & 50mpg i was getting in better conditions with my custom full exhaust...when your barely using any throttle & staying below 2700rpm...your not pushing that much airflow

i thought i was going to pick up mainly from running a 100cell race cat versus the 2 400cell cats our cars get...i guess i was wrong

that being said...the car was definetly faster on the top end the few times i did floor it with my custom exhaust...but i didn't buy this car to race it

Ah, that is not surprising then. Most exhausts around are meant for the high end, just like most other go fast goodies. Finding parts that will help the low end for a car like ours isn't easy.

Very nice, malibuguy!

I took a 300+ trip on that gas fill (52.746 MPG) and drove 45-50 MPH on rural highways and some open interstates. I was suprised that I was able to get over 50 MPG on the tank using ethanol now. With all my other + 50's I was using non-ethanol. I changed my driving technique a bit to compensate for the loss of energy using ethanol gas. I also use a stabilizer for the ethanol...1/2 to 1 oz. You get around 1-3 MPG less using ethanol blend than RBOB gas. On this present tank I'm taking another shorter trip this week. So far my first 'bar' I got 120 mi and the second was 70 mi! Better than last fill-up. We will see if I can get two in a row...

Cheers!

odds are everything in the market is going to hurt the bottom end. I think there was an intake that actually added to the bottom end, but that's it. Odds are everything else is going to hurt gas mileage without thousands of hours of research and development.

I just got a new best too, 43.6. I think the summer gas blend is helping.

I started out just wanting to average 40 MPG but when I see what some others are getting I want MORE. It will take a while to get my lifetime average up to 40.

Just got back from a long trip, mountainous terrain, not many passed us. 500km on 27l of fuel, 3 tanks. I'm happy with the mileage, thanks.

Guess I should post so I can see my avg now. didnt look at gassavers.org when I put the fil up in,lol

[malibuguy]

i wanna know how you guys are getting low 40s...i literally have to drive the crap out of mine to get low 40s...

So do I, even as far of using the A/C only going downhill when in DFCO. I don't know what to do to get more.

Think about hypermiling. Then do it, with zero regard to safety or speed minimums or anything else.

The top few guys here drive like 99.99% of people would never even dream of, never mind actually want to.

It is unrealistic for most people in most situations, as 1 lives in an extremely rural area, and another drives through extremely mountainous regions every day.

Getting over 40 mpg is a great achievement in this car without modifications.

[rningonfumes]

What do you mean zero regard for minimum speeds? or Safety?

I can break 45mpg without a thought. I drive in a relatively populated suburban area with relatively flat ground. I'm not showing off the 45. 45 was what I got before I knew anything about hypermiling. It's the number I hit when I first got the car. And 45 is what led me to googling everything up, that and at the time Bryan (up north) was posting rather consistently. I don't remember his handle- he is the one who drives in the mountains.

If you're driving while pretending that there is a CHP Officer watching your every move, ie within the law, you will break 45.

Lastly I do understand that people in more colder regions have more trouble. So make it 40 for you guys.

*gets off his soap box.

We have nothing BUT mountains around here, still mileage is fine. I don't hypermile, my only concession to FE is higher pressure in the tires.

Another problem is the BS factor; not us, but them. Anyone driving another make of vehicle that claims our FE is likely cheating or lying; either way, depend on their claim being untrue. NOBODY in our neighbourhood is getting as good FE as we are.

If you aren't getting the mileage you expected, either there is something wrong with your car, or your driving techniques, simple as that.

I have my tires set at 40psi and on the highway I do right at 70 sometimes a little less, sometime more. I even have a sub in the trunk (OK,its a 8" one, but still the box and amp and such weight 20+ pounds) and an amp for the fronts too. The only area that I see I do different than I used to, is around town. I am very conscious of how I take off at a light and acceleration in general. I take it very easy on the pedal. "Smooth as butta" The egg between foot and pedal kinda driving. I think any small car can do much better when driven like that. Remember...all those drivers with V6 and V8's have lots of torque on the low end. We dont, so if you are trying to stay up with them, your mileage takes a bigger hit since our litte gutless wonders have to work much harder to stay up with the pace. They are loafing while ours are working harder, percentage wise. I say, let them do their thing and I'll do mine. I figure I'll end up passing them up anyways since they'll be stopping at the pump much more often. I could hit 45mpg or higher probably if I slowed down on the highway some more, but I choose not too. Maybe some fill up I'll try to do no higher than 65 and see what happens. But that, for me would be hard....
