Well just to update you on my recent fuel log.
Sport GT - 5 speed.
20-Mar 25.31 30.50 404.0 7.55 31.15
23-Mar 36.00 40.04 570.0 7.02 33.48
24-Mar 18.57 22.51 284.0 7.93 29.67

9-Apr 43.98 50.45 709.3 7.11 33.07
6-May 27.02 32.68 448.0 7.29 32.25
8-May 27.50 33.25 504.0 6.60 35.65 :)
10-May 20.00 24.48 352.0 6.95 33.82
12-May 18.95 23.84 331.0 7.20 32.65
I need to do a better job of keeping all my receipts and writing
down the mileage numbers for each fill up. Still happy with the
results and still driving with fuel economy in mind.

recently I bought some STP fuel injection cleaner (red bottle and about $2.80 selling in CT), it really give me an increase for gas, average I got 260-280km half tank, I now get about 310km half tank and 580km when empty light comes up.

Hi,
I have a 2005 mazda 3 sport gt. I\'ve got my last 6 tanks reccorded.
Code:
Travel L/100km mpg mpg(I)
418 10.3 22.9 27.5
454 9.6 24.6 29.6
424 10.1 23.2 27.8
470 7.7 30.7 36.9
331 10.7 21.9 26.3
The 4th sample (470km) included about 370km on cruise at 100km/h (2800rpm)
A lot of my driving includes messing about at stoplights in the city, etobicoke area.
I was a bit dissapointed at the last sample though, 10.7L/100km sounds like too much too me for the type of driving I have been doing.

In general, are people satisfied with the fuel economy of the 2.3L engine?
-
Replying to Topic \'Fuel Economy\'
For the 2.3L in general... NO. However, there are a few 2.3L manual transmission drivers such as myself who are quite happy with the fuel economy and are achieving near advertised fuel economy #\'s.

OK - so I\'ve been doing a little measuring of my own on the economy of my \"whip\"... :)
Here are the primary results:
Date | Fuel (L) | Distance | L/100km
5/19/05 | 45.73 | 482km | 9.49
5/27/05 | 46.03 | 521km | 8.83
I\'ll keep updating this post every few weeks as I go past the break-in period..

how fast do you drive when you do highway? especially the 7.65L/100 tank? thx

this might have been answered before, but how does everyone measure their mileage and fuel consumption? It\'s not a straight-foward thing to do accurately...
I suppose one way to do it would be to fill the tank, drive, then fill it again and measure how much fuel you had to put in. but then, you\'re filling it twice and you can\'t really tell if you\'re filling it to the same level the second time...
I guess you could also fill the tank, drive and then estimate by the gauge reading how much fuel you have left and/or used up but that doesn\'t sound a whole lot accurate either...

I usually do it by filling the tank until the gas shuts off from the pump and then paying the odd amount.
Then drive and refill the same way.
The Number of litres required to refill against the km I have driven. I am sure it is not exact but it must be pretty close.
Well thats how I have been doing it *shrug*

Replying to Topic \'Fuel Economy\'
this has been an issue b?c how do you really know how much you\"re putting in> (ugh my kb is messed up time to reboot) but i for one fill up all the way all the time and record it in a spreadsheet to track the mileage>>> but each pump will have a different cut off so unless you use the same station all the time (same pump actually) then you can\"t be too accurate but good enough to average out in the long run

I calculate my fuel economy based on gas reciepts and trip computer readings. The volume of gas put in the tank is indicated on the recipt (most of the time) and all one needs to do is write on the receipt the number of kilometres that the volume of fuel netted them, I always write it down immediately upon refuelling and then reset the trip computer to 0 for the next fillup. A quick way to determine the fuel economy for L/100km is to use the following equation:
((Litres pumped into tank) x 100) / number of kilometres off trip computer
example:
(42.25L x 100) / 595km
= 7.101 L/100km
Since I measuring fuel economy given actual kilometreage and fuel consumed it is accurate. I don\'t need to assume a full fuel-fillup every time since the volume is printed on the receipt. You can set up an excel spreadsheet if you are as nuts as I am!

oh man.. case of the mondays for me today..
i do enter the exact volume of fuel.. i really was asleep when i wrote my previous post and a spreadsheet is the way to go.. and no you\'re not nuts.. unless we both are..
also for those who want to see their long term fuel consumption do NOT average the averages.. add up all the litres of fuel you consumed and the mileage travelled and use teh equation by cstraw (more accurate than taking the average of your averaged results) anyway..
i find the fuel consumption (even in traffic) has been much better lately (eg. summertime) when the car doesn\'t have to run UBER rich for a long time - till the engine warms up. so if you\'re getting crappy mileage now, it\'s only gonna get worse :(

Interesting...
I get anywhere from 580km to 640km on a full tank...
I do both highway and city driving.
But Seeing most of your records I think I\'ll keep more actuate records
But still 600km a tank average hey I can\'t complain hehe
:D

I do 90% city driving in traffic (1hr each way to work) and get at least 530 kms to a tank. The last time I filled up it was 43L@540KMS (7.96L/100KM). I find the fuel efficiency pretty good in this car.

what are your shift points and how hard do you accelerate? do you coast a lot?
-
Replying to Topic \'Fuel Economy\'
Usually shift aroung 3500RPM. I dont accellerate hard unless Im pissed!!

wow.. i usually shft at 2500-3K depending on what gear and what the situation is.. although i do like to shift @ redline on occasion ;)
but with shifting at 3500RPM i don\'t hink i could ever do < 8L/100km
hmm i guess i can try it on the next tank
what about A/C? windows down? for me < 60kph windows down unless it\'s really humid or it\'s stop and go with no breeze. anything over 60kph A/C

Replying to Topic \'Fuel Economy\'
I also shift somewhere b/t 2200-2800rpm and would never think I could get mileage better than 8L/100km
tell me how you do it! :D

A/C off and windows down most of the time. If I use the A/C I will get approx 500KM/tank. I dont understand the difference in fuel economy, my car is a Dec. 04 production date. What production date is everyone elses? I think Electra_fire gets better gas mileage than I do...I would be curious to know the production date on that car as well.

well AC should be better on the highway due to the drag caused by open windows. and when you\'re stuck in traffic the AC uses up a lot more juice.. also.. electra fire has a 2.0L model so the comparison isn\'t valid.. and finally the sedan weighs about 30kg less than the sport as well as has a lower coefficient of drag (0.332 vs 0.346 - 17\" wheel models)
