Oh I understand now. I don't doubt that it's a good tip. I know I used to push mine up slightly past 43 mph, as per thegrad's tip, to force it to shift into 5th gear and then I'd drop back if I was going to be on a stretch where it would be 40 mph for an extended period. When I did this my car would be running about 1200 rpm. No sense in sticking in 4th for a long stretch.
 
I'll have to start paying more attention so I might be able to make use of the same technique.
 
I find it amazing how slight variances in the gearing of a given car can produce such differing amounts of rpm. My brother's car, a 94 Corolla 5-speed manual, pushes 4,000 rpm at 75 mph, while mine, 03 Accord LX Coupe 4-cyl, is only running about 2500 at 75 mph and barely 2750 at 80. (/random tangent over)

Is my Car Broke by bud_foxx44

Folks, I have a I4 Auto Accord 2009 and I am getting lousy mileage. My first 3 tanks are averaging 22 to 23 MPG. I have a 78 mile commute one way with about 65 of them solely highway and the rest 40 to 50 MPH with some lights. I should be getting high 20's to over 30. Do I need to give it more time to break in?
 
Thanks in advance

Your expectations are high and your mileage is low. With that drive I would expect more in the mid- to upper-20s. Most of my driving is a 35 mile commute with the first 5 and last 2 miles at 35-50MPH with a few traffic lights, the rest somewhat curvy back roads with an occasional straightaway. I usually get 25-27MPG which is right where the EPA said my mileage should be. The ONLY time I ever got over 30MPG was on 100% highway trips. I didn't notice much improvement after break-in - these mileages were realized from the get-go.
 
That being said, 22-23MPG seems low. Check your tire pressure, make sure you shift into D and not D3 (easy to do), and use decent quality gasoline.

How fast are you driving on the highway?

High speeds kill mileage, especially if you are using AC.

Driving habits and mileage by tallman1

I've had the chance to be a passenger a few times lately which has allowed me to observe others' driving habits. I've come to the conclusion that many people don't anticipate very well. It doesn't make sense to me to punch the gas pedal when you can see something ahead that will make you stop or slow down, such as a red light or slow moving traffic.
 
Technically, every time you use the brakes, you are wasting that energy. (Yes, I know that you have to be reasonable about this.) I wonder how much better mileage might be for some folks if they just could learn some different driving techniques.
 
I also understand the fun in quick acceleration. And there are plenty of folks who couldn't care less about mileage.
 
I'll bet EZ and Dudley go easy on the brakes. Of course, like me, they have manuals with the increased engine braking.

I drive between 75 and 80 usually with my cruise control on. Remember, I am driving from North to South Jersey which means some breaking on the highway but not too much. I have read previous posts where people say it takes 12,000 to 15K miles to break in. I really can't believe that.

Keep it under 70 and you should easily do high 20's overall. I have an 08 V6 and I get 25 mpg with 50/50 driving.

O. K. That's the answer. The difference in mpg between 70 and 55 is 15% add another 5% to 75 and another 5% to 80.

Excellent point about the brakes. Yes every time you use them you waste energy. Obviously you can't avoid them completely, but anticipation is your friend. Glide up to stops, why give the car gas when you are going to stop anyway?
 
Yes, my brakes tend to last forever - my last car ('90 Integra MT) the front brakes lasted until 190,000 miles.
