Fuel Economy

[Spahrticus]

Mine is horrible... However, I feel like it's wonderful when I compare to my M3 which is 15-25MPG and $60 to fill up...

just got 46mpg this morning on a full tank :D im happy with that

[MattS.]

I figured 32 mpg on the dealer tank with town/hwy miles combined. I am on the second tank now, but let my daughter drive on her learner's permit to get some practice. I'm sure that will not help much.... I hope to improve on overall mpg once I get it broken in, and learn more fuel efficient driving habits. I'll SOMETIMES miss my Wrangler I just traded in on my new Yaris ;)

How are people getting over 40mph on their cars? Seems like the newer models get better gas mileage. I have an 07.

Look at the stickies in this section and go to the very beginning where most of the tips are. I got my biggest improvement from DFCO (2nd sticky).

Trying a new driving style and got 41mpg on my last tank I'm going to raise the tire pressure in the near future. Anyone get any mileage improvements with high end spark plugs?

Manual transmission, no road rage, rural roads, and thinking ahead. I live in a semi-rural area, and we have broad shallowly sloped mountainsides where you can coast on the downhill leg for miles. I drive the same handful of roads weekly, and know how to get the most out of them. Also, 45-50 MPH highway speeds are normal here. I'm currently averaging about 45 MPG on my car's 1 year birthday.

43.94 mpg on my latest tank, now I have to wait a long while before I get to fillup again! I actually look forward to filling up, how sick is that?

50/50 mix of freeway (65 mph TOPS) , secondary, and less then secondary roads, straight gas no ethanol ever.

It would be nice if pure gas was still available in PA... I miss it!

Cheers!

ive been tracking my economy the last couple tanks since getting the s/c installed

first tank, 7.77L/100km (30.2mpg)....a week of city commuting in cold (almost freezing) weather and a romp from kitchener to mississauga (45min) and back doing about 125kph (85mph)

last tank was 6.86L/100km (34.3mpg) which was a week of city commuting (warmer weather now...about 10C in the mornings and a drive from kitchener to niagara falls (1.5h), niagara falls to burlington (45min), burlington to kitchener (45min) doing about 110kph (70mph)

both tanks had intermittent romping on the s/c for fun...moreso on the last tank since i was w/o wife and/or child for most of my trip...

thats pretty badass

The ECO is about 1 m.p.g. less than the calculated gas mileage , could very well be 42 m.p.g.. Set at 94 , have to reset to 95 . Mostly 2 people , tires at 35 p.s.i. , VALERO 87 w/ 10% ethanol , and average speed of 50 . Not bad , so far . This is the '08 auto sedan .

[Hershey]

Same here , about 2 mile climb up a very steep hill 5 or somtimes 6 days out of the week .

Also same here. I routinely can drive into Inkom and get 70+ mpg, it's 1,000' below. It's that long pull back up to get home that gets less then 20 mpg. Still, when I get home, it's in the 40's.

Owned the car for less than two weeks, I had a small opportunity to test out nearly all Highway mpg, I tried to stay below 2500rpm and managed

119.7miles at 2.366gallons = 50.59mpg

[Hershey]

The car got 40.77 m.p.g. calculated , while the ECO read 40.6 . Going to leave the ECO at 94 . That way it's actually doing better than the ECO overall m.p.g. display . It took 8.621 gallons of SUNOCO 87 w/ 10% ethanol at 1 click . The trip A was 351.5 miles . New Continental Pro Contact Eco Plus tires set at 35 p.s.i. . Rides , handles much better and a bit quieter with these tires . Gas mileage seems to be the same as witht the Potenza RE 92 .

6th Bar drop (3/8) > 50 mi (415)

got 51.98mpg last tank...i kinda killed some of it on my last commute home, i kinda had to rush to catch a store before it closed & i got out of work late...but this proves the car prefers the stock exhaust for best fuel economy
