Default MPG is only 19.5 for first 2000 miles

Have had the car now for 2000 (very happy and enjoyed) miles.

But Im only getting about 20mpg at every fill up. True, my daily commute is about 5 miles, but as of late I've been running out the airport a fair bit (20+ miles). People on this board post that they are getting 25 in city driving...

What do you all typicall see with city driving?

I think this will get moved to the general forum. At any rate, I'd say that was about normal for me. My first few thousand miles seemed to be right around 20... now I'm adjusted to the car and get about 23-24. Much of it is getting the feel right so you spend less time with the clutch in, know where to shift during cruising, ect. I think I also drove the car harder when I was excited to have just bought it.

Thanks for the reply. I remember reading that letting the car engine brake (or even slow in gear), shoots the A/F ratio way way up meaning there is no fuel consumption (or rather little). I suppose that is more efficient than cruising to a stop with the car in neutral...

That will save your brakes but use more fuel...

I only downshift like that when I want to be ready to speed up quicky as the conditions change. Brake pads are much cheaper than clutch+tranny(especially on the S2000).

I think that your mileage is about like mine for short commutes, although mine is around 25 on longer, freeway drives. I'm sorry to say that with the slightly over-rated speedometer (reads a little fast, and I presume a little longer than actual miles), our MPG is probably a percent or two lower than what we have calculated. Gladly this will only amount to a fraction of a MPH. I've got 3K on my 05 now and think that the engine feels a little looser and it coasts just a little better. Maybe it's just my familiarity with the car and placebo effect. I wonder if there is a slight MPG difference between the California 91 octane that I use and the 93 octane that is available in other states. Enjoy your S; I love mine.

give it time. this car takes a good 7500 miles to really breakin properly. the thread could probably stay here, since he is technically trying to figure out if there is something wrong with his car.

I wouldn't worry about it. It's all about driving style. Under 3K I probably got 16-18mpg for mixed city highway driving. Now I'm probably 75% highway and I get only 22MPG. Only if I'm driving all highway do I get 29MPG.

Cool

I was interested to see this thread. I just crossed 3000 miles in my '05 (in 3 weeks!) and have been pleasantly surprised by my mileage. When I filled up today, I realized that I had gotten 27 mpg from my last tank. Admittedly, it was a road trip spent primarilty on the interstate at 70-90 mph. My car has also not burned one bit of oil during the break-in period.

I have heard that there is large discretion between engines in our cars because of the hand built nature of the car. Looks like I got a tight one!

Holler.
