Yup, acutally it very easy.:D :D Either you can use the calculator or the unitary method.Quote:
INDUSBREED...just wondering---do you know how to calculate L/100km?
Its not as complicated as Solving 4th Order diffrential equations or Advanced Vector Algebra.
FYI: Lifetime member of IEEE.;) ;)
Anytime, Everfeb. :)Quote:

So I\'m just going to carry on doing my Mileage checks manually. Only takes a few minutes and not very often as I don\'t put a lot of km\'s on the 3. But thanks very much.

Now for an update:
20-Feb-05
10.681 L/100km, 22.022 MPG
City 40%, Hwy 60%
21-Feb-05
10.201 L/100km, 23.057 MPG
City 30%, Hwy 70%
Overall average (with nearly 10,000km on the odometer): 10.359 L/100km, 23.034 MPG
Here\'s a decent read that Everfeb started on the other forums (although no one really answered his initial question):
Improved Gas Mileage!!!
Institute of Electrical and Electronics Engineers... is alright, but not as exciting as SAE. :DQuote:

you think so??.....:D :D :DQuote:

Just thought I\'d add my two cents...
Just went on a trip, 95% highway driving, average 130km/h.
45.424 litres
591 km
This equals 13.01 km/litre which translates to 7.68 L/100km or 30.6 mpg.
And for those who don\'t know, I have a GT, 5-speed.
Everything seems to be in line with Mazda\'s published numbers.
I just did a trip to Massachusetts and got similar results. My best tank (almost all highway).Quote:

110 km/hr? how many tercels and hyundai accents did you get passed by? :p
Well, this is the Fuel Economy thread after all. The point is that if you drive like a granny, you can actually achieve or get very close to the claimed fuel economy numbers for the car. You can of course pass all the Tercels and Accents that you like, you can speed, shift at 7k, race every Civic on the road and take corners on two wheels, but if that is how you drive you lose your right to complain about how much time and money you spend at the gas pump.Quote:

I guess that I should have added a few :p s of my own. My response was meant to be light hearted, not critical. My apologies if it was interpreted otherwise :sarc .
Hi Everyone,
I just improved my gas mileage!
From Jan. 27, 2005 to Mar. 17, 2005, I average 13.08 L/100 km. w/
Airflow selector dial on \"Defroster and Floor vents\"
Fan control dial on \"2\"
Temp. control dial on (from center to) \"2nd or 3rd line\" on the right.
And from my last 2 pumps;
Mar. 23, \'05 ----- 25.787 Li ----- 226.9 km ----- 11.365 Li/100 km
Arp. 03, \'05 ----- 44.478 Li ----- 435.5 km ----- 10.213 Li/100 km
Airflow selector dial on \"Dashboard vents\" ..... (will try Dashboard & Floor next time)
Fan control dial on \"1\"
Temp. control dial on (from center to) \"2nd line\" on the right
I have a GT sedan, leather, auto .... city driving (no highways) .... odometer - 3501 km.
10.213 is very close to 9.8! Thanks to everyone for the info\'s. tips and advise.
TM3 is GREAT!
Well here is my updated gas log. I am happy so far, and to echo Eric\'s comments on fuel economy, I drive conservativel and attain near advertised fuel economy ratings, it can be done. This is with a 2004 Mazda 3 Sport 5speed.

Great numbers cstraw!
I just filled up my tank.
615.3 km
43.580 liters
7.08 L/100 km
39.88 miles per imp. gallon
33.21 miles per US gallon
This was regular commuting for me. 70% highway, 30% city.
The warmer weather seems to really help fuel economy. The car now has 8200 klicks on it.

I\'ve had my car exactly one year today. My numbers pretty much match yours. I have a GT HB with 5spd, 38K so far with a low of 26.6 mpg & a high of 36.7 mpg. I mostly get around 30 mpg. I do however drive @ 120 kph & up on the 401 & 407 & go with the traffic flow everywhere else.
I gave up logging my L/100km but with the intake on, my mileage has been slightly better! After fill-up, I would usually get to the mid-point of the fuel gauge and it\'d be at 200km (give or take a few of course). After the intake and fill-ups, I noticed I get at least 50km more each time. I\'m on my third fill-up now. (Yeah for some reason my car has sh*t mileage from the start... for the first ten or so fill-ups I would always get 10.xxL/100km. Even when I tried to baby it. No idea what it was.
Here are my latest numbers if anyone is interested..
2.0L automatic, 90% rush hour city driving
467km for 37.735L => 8L/100km
Before when I drove 70% non rush hour hwy, I get about 7.6L/100km. So I am pleasantly surprised that I can get by on 8L/100km.
I have a GT-HB 5MT for only few weeks, before I got this car, I was driving a 01 Protege GT (2.0L, AT). By comparing the fuel economy, I found that MAZDA had actually got an improved fuel efficiency, for the Protege (it has a same 55L fuel tank) I can drive up to around 450KM and just before the fuel light to lit up, but for my new 3, it did about the some kilometres, but which is a 2.3L engine compare to the 2.0L one.......
However; I think MAZDA should work harder to improve its fuel efficiency. 1 of my frd is driving a RSX 5MT (not the TYPE S), and he has a smaller tank (50L), he could drive his car at an average of 600+ KM full tank, or even when he drove more GENTLE (not to rev the engine):D , he could even reach 700KM.......moreover, even a 4-cyl ACCORD would cost less fuels than us.....:(
What other factors could impact the fuel economy besides lead foot syndrome, unnecessary weight in the car, tire pressure? I\'ve been babying my drive the past two weeks 75% city roads, nothing out of the ordinary being carried around in the car (at most it\'s been my gf and myself, combined less than 240lbs), and tire pressure is at 32lbs psi, give or take a pound.
After fill up on Apr 10th, I calculated 10.15L/100km. Just this evening after fill-up, I calculated 10.00L/100km. W T F?!?!?! Average for this car has been 10.67L/100km for all the times I\'ve logged.
My first Mazda3, same exact specs and same exact driving style; average 9.13L/100km and majority of the time had between 8.2L/100km to 9.5L/100km.
What could possibly be different on my present 3 compared to the first 3 that causes such an increase in fuel economy?
No wonder Honda knows how to build cars eat less gas. ;) I know \'cos I drove a Honda before and all the other cars in my family are Honda/Acura.Quote:

Admit it or not, people drive faster and more aggressively after winter, intentionally or unintentionally. And it think your Draxas exhaust + AEM CAI keep seducing your right foot to press harder :DQuote:

Yeah I asked my gf last night about my driving. She says I am a lot more harder on the acceleration in this second car compared to the first 3 i had. Although all times I\'ve logged fuel economy on the first 3, the numbers were 90% 8.xL/100km even up to the last fill-up prior to the accident. That\'s why i keep thinking there must be something else inside the car (engine bay) that causes such poor fuel economy in this 3 now.
Could it be the CAI?
For some reason fuel economy is constantly dropping on my 3... Lately I can only get approx. 450km for a full tank... What\'s going on?!?!
CAI should improve fuel economy... unless that\'s a myth all along? :(
Don\'t quote me on it. My info came from Mr Fatty...
Well with CAI it should technically improve MPG but because we all prefer to hear the engine roar, we stomp the gas more/harder. :D
