I got 18 MPG all city on my first tankful. I know it will get better as the miles increase. I expect to at least hit low 20s for highway use.

BTW....anyone who has IUP know how accurate the computer is for reporting MPG?

This is what I'm saying. I'm lucky to get 21 mpg on an all hwy road trip. I average between 14-16mpg on a mix of city/hwy. I don't really care because I didn't buy this car for good gas mileage but I am jeolous of the others here that are getting way better mpg with the exact same car.

Well considering that the computer knows exactly how much gas it is squirting into the cylinders and it knows exactly how many miles you have gone I would expect that this would be significantly more accurate than the traditional fill it up and compare to trip odo method.

But I don't have any actual evidence to back up my theory.

If the computer indeed is measuring the exact amount of gas it's "injecting" and it indeed is taking into account the mileage driven, then yes, it should be more accurate than taking mileage odo readings, amount of gas per fill-up.

But, I don't know whay the trip computer is actually measuring. Does anyone know this?

The trip odo is just for measuring miles for say if you wanted to go somewhere and back. It let's you know how many miles certain things are away if that's what you would want to use it for. Or you could use it to get a rough estimate on how many MPG you are getting. That's what I do, want to talk about confusing though, my grandmother's old Mitsubishi Galant had 2 trip odos!!

I haven't seen the specs on the V6 but I wouldn't be surprised that the GT gets better gas mileage. Stronger motor moving the same amount of weight. My example would be my friend. He has a 2002 dodge dakota V6 and a V8. His vs gets 14mpg and his V8 gets 16mpg. His v6 has to work harder to move the weight of the truck, therefore uses more gas.

I'm not sure how accurately the computer measures the gasoline used. But it seems to me that calculating it the old fashion way is the more accurate method, especially over a lot of miles (not per tankful)---you know exactly how many gallons you've purchased, and exactly how many miles you have driven.

Divide the miles driven by the gallons pumped, over 1,000 / 2,000 / 3,000 / 5,000 miles, and you will know you're MPGs with deadly accuracy.

Again, doing the math per tankful will not be terribly accurate b/c of the numerous variables; but if you track it over time it will be very accurate; in fact, the longer the time and distance, the more accurate your answer will be.

12 mpg.

almost all city, shifting late

drive slower

OK, when I do the math---since the last time I reset the trip meter at 156 miles, I have driven 1,617.2 miles, and pumped to the brim of the tank / filler neck 82.504 gallons. The math says I have averaged 19.60147 MPG; the computer says I have averaged exactly 20.0 MPG.

The computer is close, but not quite deadly accurate. It would appear that there are some variables in the way the computer calculates.

Again, over time the math accuracy will increase with miles driven and gallons pumped; any error will be spread over a larger base of data, with the result that the error rate diminishes over time.

I like the computer's average MPG better; but I'd have to go with the math for the real answer.

I seem to get between 19 and 20 combined city-highway, which is a lot better then my SUV, and a lot more fun, too.

Want better gas mileage .... go buy a Focus ...

Badandy

macoin-Maybe the computer is more accurate. You have pumped that many gallons in, but are you sure you have used EVERY last drop of it to go that distance?

My one concern about gas mileage stems from the anticipation that by labor day we'll be paying close to $3 per gallon for unleaded gas. Any by the time I have this car paid off we'll be paying Europe prices while our elected officials still drive around in limo's at our expense...

Ahh... you just gotta love Government!!!

Giddyup

I'm averaging between 13-14 MPG, and it's all city driving. At the current $2.45 gallon, it's eating me alive.......but my slow death will always be with a smile on my face

maucoin65

Badandy---just saw your reply / comment. No, of course I'm not sure I've used every last drop. But that's why the margin of error should dimish over time---because you'll be spreading those unused last few drops over more and more miles driven, so the average MPG impact / error will get smaller over time.

I haven't read anywhere exactly how the computer measures the gasoline or reports the data. The two methods are close in result, and I suspect the old fashioned math will draw closer to the computer calculated answer over time.

The spread at that time (above) was only 19.6 vs 20.0. Not much margin already, and again, that variance margin should diminsh over time. I haven't compared it lately to see.

You gotta be a numbers guy / gal to care or even think about this stuff, I suppose. The car is still a kick to drive and own, regardless of the relative fuel economy.

mines at 11.9 avg mpg. 470 miles on it......ive been taking it alittle easier its gonna probably hit 12 soon. i gotta do alotta highway driving tomarrow
