I have read some of the MPG threads and they are all over the board and hard to keep track of who is getting what. So I want to ask these specifics:

How many miles does your MCS currently have?
Auto or 6sp
Actual MPG (not computer)
Driven how in a week


My answers:
3400
6sp
29.7 mpg
my daily commute is 102 miles round trip on a 55 mph highway with a few stop lights closer to the office.

I can't seem to break into the 30 mpg . Is there a secret or are the numbers they advertise on the sticker un-attainable?
Just curious.

40,000km or about 25460 miles
6 spd
between 10l/100km to worst ive seen 13l/100km, someone do the math, im consistently getting mid to high 10l/100km

a good mix of highway and city driving, around 40% highway, 60% city

 

'02 MCS currently at 42k miles
-6 spd
-everyday driving ~31-32 mpg (70% highway) of 40 miles/day
-high of 37 mpg on an all highway trip from Jax to Tampa but have gotten higher for shorter periods when driving in the 50 mph range.

 

'05 MCS. ~8000 mi. Getting 33+ on the highway and ~high 20's/low 30's just around.

 

i saw about 32 mpg on a trip from Long Island to Dayton, Ohio and my car had about 36k miles back then. I was doing around 8o mh most of the time with a few stints over that.

 

05 MCS, 6 spd, @1600 mi,
26+ mpg, 70% highway @75mph, 30% urban,
daily commuter
looks like I'm under achieving, but having a ball! hope things will improve with age.

 

With my '02 MC I used to do the MPG calculation everytime I filled up. Ever since I got my '05 MCS with the computer, I've gotten lazy about making calculalations at the pump. I'm curious .... what kinds of discrepancies are people finding with the OBC? Wheel diameter changes could certainly alter results on the OBC AND pumpside calculations.

 

~24,000 miles
6 speed
~27 mpg average (low of 24; high of 30 mpg)
50:50 mixed city -highway

 

05 MCS
Manual
Just shy of 11,000 miles
24 to 25 mpgs from 90% city driving

 

2005 Manual
12000~ miles
29.01 lifetime MPG (calculated since day one)
25% city, 50% highway, 25% mountain

If I keep to the speed limit on the highway I can get 32-34 MPG. Doesn't happen very often. Club runs are hell on fuel economy, also.

How many miles does your MCS currently have? about 27,000

Auto or 6sp: 6 speed, of course.

Actual MPG (not computer): Best? about 34-35 mpg; average? 29 mpg

Driven how in a week: I drive at least 300 miles a week. My commute is about 15 miles on country roads, and since there are few red lights and I have to keep the speed down to 55 or so, I think I am more capable, compared to most mini drivers, to get fairly high gas milage. For the one time I got in the mid 30s, I was very good and did absolutely no spirited driving at all.

 

2005 MCS 6spd
1800mi
19.5 - 20mpg. OBC, which seems very accurate to real world the times I've calculated it.
Back road driving. Lots of lights / go-stop-go driving.
Damn... I thought i'd be getting at least 24-25.
I do not drive w/ a light foot.

 

60,000 miles
6 sp
a) 22 mpg, b) 35 mpg, c) 30 mpg
a) autobahn road trips avg. 90+mph, b) back roads sight seeing avg. 30-40mph (kept in higher gears than normal), c) commuting 40 miles each way, avg. 75mph

The milage numbers seem flip/flopped, but autobahn driving is basically a roadrace--I've hit the limiter a few times out there; further, keeping it in high gear at low speeds with light load on the engine worked really well for conservation.

Ive seen 40+ on road trips

My drive to work is about in between 20 and 30 since i live in the city.

 

2005 MCS w/20,000 miles
6sp
27 mpg (average mileage over last 3k miles)
about 90% city driving, ocassional road trips to FL

 

40+ - C'mon? Let us know where you bought that calulator. haha

 

How many miles does your MCS currently have? ~7500
Auto or 6sp 6 sp
Actual MPG (not computer) between 7 mpg and 30 mpg
Driven how in a week mostly in heavy volume commuting


I get about 80 miles to a tankful when driven on the track which is about 7 mpg

I get about 20 mph during a mostly 1st and 2nd gear commute in boston traffic which is very good...

I get close to 30 mpg driving conservatively on the highway on a long trip, where computer indicates 32 mpg

 

How many miles does your MCS currently have? >9000
6sp
Actual MPG 25mpg
Driven how in a week 85% highway at about 75-80 on Sawgrass Expressway (trying to keep up with the flow)

Best mileage was 32mpg when I was running no more than 55mph and conserving fuel during the gas shortage after Hurricane Wilma.

 

About 48,000 miles
6sp
Actual mpg pretty consistent 31.5 to 32.5

Daily commute, almost 90 miles round trip mostly highway, but plenty of stop and go traffic (San Francisco Bay Area commute).

The discrepency between the computer and calculated is almost 10% (reports over 35mpg average when I calculate about 32)

I found on long trips through the central valley down I-5 when I am often pushing 90mph to keep up with left lane traffic, mpg drops below 30.

A full tanks worth of city stop and go will bring it down to about 26mpg. I think the weight for its size takes a big toll here.

 

12000
6sp
29 mpg avg of every gallon ever put in the tank. :smile:
35 mpg best ever. On the x-way, early morning , air off, 75 mph.

 

i have heard that things like roof racks and driving lights can have a big influence on decreasing MPG. I have the driving lights and wondered if other people have noticed a decrease in their MPG?

 

06 MCSm
1050 miles

25.0 mpg in traffic.... traffic sucks & blows... a natural phenomenon...
26+ on open road, over the weekend....

 

Hah! I can beat this. I average about 19MPG. That's about 100% city driving up and down the San Francisco hills and stopping at stop signs at just about every corner.

 

Kim,
Auto transmission would get lower mpg than manual.
Check your tire pressures each week and make them about 34 to 37 psi
Don't idle on warm up for long, always check your air filter every 6 months and for best mpg use only premium fuel. I'd expect your mpg to increase since you are still under 4000 miles driven.

When new, my 2003 MCS 6 spd got-
33 mpg on 90% highway driving
27-28 mpg in mixed urban/highway 60% driving

Now after 3 years of modding
I get about 25 mpg in mixed urban/highway driving (there are no long stretches of highway free of traffic on an island).

 

That was goin by the on board comp, but goin by a calc its 25
