I can't believe I'm down to bitching about this. Shows how good the car is, overall. Anyway.....I've got 700 miles on my 'speed3 and the fuel mileage is pretty poor. 20.1mph on my 20 mile commute to work. It's a split between stoplight to stoplight and freeway crusing. I haven't been abusing the engine at all, not even taking it over 4000rpms until I hit 600 miles. Just curious what the rest of you are seeing. I'm hopeful (but doubtful) that more miles on the engine gets somewhat better mileage. Then again, it might be the -5 deg cold starts sucking down a little fuel.

Anyway, does 20mpg sound low or about par?

Edited to say nevermind, I answered my own question with that newfangled feature called "search".....

I've been getting 23 mpg nearly every tankfull regardless of how I drive. Odd. I don't baby the car. Feeling the torque this thing has is one of the main reasons I look forward to the ride home each day. I tried to get the best possible mileage on this last tank by not romping on it (at all) and paying attention to the computer for the highest numbers on my normal route. It was brutal and I only managed 24.4 mpg. :?

I'm back to having fun. :D

In stop and go traffic, shifting 1st-3rd-5th works well if you let first wind out to around 3500rpm. Third to fifth isn't much of a jump.

2.5K miles on her now.

Yes it should slowly get better. At least mine did. I started around 18 mpg and now I am averaging just under twenty. Of course you have to facture in the heavy right foot days...

I've averaged 24 with a mix of hwy and city, probably around 50/50 on average mostly hwy during week and mostly city during weekend. I have my winter tires on so even when the roads are good I can't get on it to much, but I still have a heavy right foot. I was getting 29 mpg from my 04 so I'm real pleased with the mileage I'm getting.

Yeah, the only way to get good mileage is get a boost gauge and stay off boost. Somebody was managing to 26-27 mpg IIRC by staying off boost. Personally, I'd rather have fun and get the same gas mileage I've been getting since the first tank: 19-20 mpg.

are you guys calculating from your trip computers because they seem to overestimate mileage. I get 18 mpg consistantly. It used to bother me but now I don't give a shit, because the car is so much fun.

there was a 28-29 i think cosmicbluems3 had it - but it was almost all highway mileage.

I bought/am buying this car to have a fun, practical car to drive, it gets great mileage in my opinion, my el camino got 16-17MPG....that was highway mileage! :)

I keep stats on every gas fill-up cause I want a full record for the car thru it's whole life. Here is what i have seen thus far:

Trip Mileage Gallons At Fillup Total Fillup Cost Miles per Gallon
231.0 11.664 $29.15 19.80452675
292.1 12.229 $28.24 23.88584512
201.1 8.7200 $18.75 23.06192661
280.3 12.650 $32.75 22.15810277


If I can get 23-24 I will not be upset. I was hoping for 24-26 but I figured it would be around the 23 mark. I hate the ratings they put on cars cause they lie. I do mostly highway but some town/city as well.

I have about 5,000 miles on it now, and have been consistently getting 25-30 mpg, mostly highway like driving, fairly conservative but I do enjoy flooring it every now and then. Hasn't changed much since new....I would note that the trip computer is NOT accurate, typically off about 8%, so do your own calculations.

I don't have a trip computer- guess the sport does nto come with that but the touring might.

Another note to add is that in the winter they add stuff to the gas that might reduce gas milage. I know they used to stop usign the additive in the summer time and you would get better milage but I am not sure if they still remove it for summer gas anymore or not. YOu know global warming and what not.

1000 miles on her so far and I am getting about 20mpg. This is a big upgrade from my 2004 Xterra which got 13 mpg and my 1988 S/C mustang that got 12 mpg.

Mine quotes below actual mileage by 1-2 mpg.

No trip computer as I don't have it, just simple math. I don't worry about the mileage as I buy my cars to drive and this can't get worse than my old 4x4 dodge did (9mpg) unless something is very wrong or I've managed to get insane HP out of it.

It is hard for me to beleive the guy that said he is gettign 25-30 MPG. I am not sayign that is not poassiable but I would liek to know where he lives, what the weather is like where he is and what gas he is using. Jsut knowing the sticker says 20-26 tells me you are probably goign to get a little worse than half the difference between those two numbers. (20+26) / 2 = 23mpg

Simple math and seems to be pretty accurate on most cars.

I would also liek to know where people are gettign their information from. You can't trust trip computers and all the fancy electronics. You need to do it with simple math at the pump. I go to the gas station and fill up and when the hose stops pumping I take it out. I don't top off or anyhting and that way I get a more accurate reading of gallons added each time. Then I use that and divide it into my miles accumulated for that tank of gas.

I envy you guys. I still haven't bought this and am still in my SVT focus. It has .3 liters less displacement, NO forced induction, weighs less, 100 less hp, 140 less torque, and I only get 23 in the city. Oh, and I still have to fill with 91+ octane. Ford is not known for having fuel efficient vehicles so I shoulda known.

Kahunab14,
Just think, you can look forward to an extra 90hp and 100+tq and not give up much if anything in the way of fuel mileage.

My sticker says 20-28. And if you read the small print it has estimates of 17-23 in the city and 23-33 on highway.

Using math, not the trip computer I have been seeing 23-25 mpg. Granted, my commute is mostly highway and I am barely out of break-in so I have still been taking it easy. I am happy with the mpg I have been seeing. I expect it will get better, especially when I start using cruise control and the engine breaks-in.

I use 93 octane and live in the Northeast. Temperatures have been 15-25F lately.
