backwards fuel economy?

[Golddeenoh]

anyone else getting worse gas mileage on the highway than in the city?

I get around 36 mpg city but if i drive on the highway I get 29-31

granted i drive it a little roughly.

[DJYojimbo]

is it really windy? Are there a lot of uphills? How fast are you going? I think all these will definitely mess with ur highway mpg

[Golddeenoh]

I go with the flow, but i think if i stay at around 60 mph then I would get better gas mileage. but the highway i find myself on is 70 mph and everyone is doing 80 mph, so keeping up makes my mpg go down.

in the city i get to 5th gear as quickly as possible and cruise down the road at 38 mph getting around 58 mpg, 45 seems to be ideal speed but I prefer not to do that in a 35 MPH.

[why?]

So you drive for gas mileage in the city, but don't on the highway. That's the problem.

36 mpg in city conditions is really really good. Realize your city mileage is better than the overall and highway mileage of the majority of cars for sale in the history of cars for sale.

If you stuck the cruise control on the highway to the posted speed limit you'd get much better highway mileage.

If you are really in a bad mood, and want to piss the world off, stick the cruise control at 10 mph below the speed limit. Fun stuff.

i don't have cruise control, wish i did but i'm too poor for that right now.

City means what? Creeping from traffic light to traffic light? On most of my drive to work I am on roads with almost no traffic lights, but with hills. Speed limit around 45 mph. I can get 47-52 mpg usually.
On the highway driving 70 I will usually get about 38 MPG.

[why?]

For me it means my commute to work is 3 miles. So barely any time to get the car warmed up. Of course I do get the benefit of living on a main road with a speed limit of 50 to help out my less than ten minute commute.

My last tank was 34.85 mpg.

If you can go 45 with no stop, that is highway conditions, and the conditions cars are tested on for gas mileage. They just take 20% of the top and assume it will somehow equal real world conditions.

[Amdkt7]

I use to live .9 miles from work. I often walked... I would rather live close to work and get poor gas mileage then live 20 miles from work and get 50.

[why?]

I agree completely. I've done the long commute thing, can't stand it.

Get some Seafoam fuel additive. Use it in the tank and get back to us.

Get some Seafoam fuel additive. Use it in the tank and get back to us.

but my in city fuel economy is above rated value, and i only have 45k miles on the car so it has not had enough use to be dirty enough to have that drastic of a change.

basically the sweet spot is 45 mph, in 5th gear, at 1900-2085 rpm. if i take alternate routes to get where i am going i can improve my mpg greatly, but i would rather take a quicker route to get to where I am going.

[why?]

Just slow down on the highway. Nothing wrong with letting everyone pass you.

And CTScott sells the Cruise Control kit rather inexpensively. You could probably install it yourself.

Seafoam is not a miracle cure all.

I drive 43 miles one way to work 5 days a week. Work overtime about 1.5 days a month. Yikes! get about 34 miles per gallon. Start off fast, and go faster then I should. That's all I'm saying. Also less than average stop and go.

I have noticed my Interstate travel nets me slightly lower MPG, but nothing drastic. I still obtain higher fuel mileage than rated.
