*Kilometers since last fill: 112.3km
*Liters filled: 11.96L of Shell 87
Mileage: 47,500km

Avg fuel economy for the above test (112.3km of 100% city driving, with a drive up a steep parking ramp every morning from an engine that has been started cold and allowed to warm up to 1100rpm) = 10.65L/100km

Measured at the pump (trip computer is wayyyy off at like 13L/100km). I expected worse figures, so I think that the above number is acceptable, and could be better if I practiced better fuel economy driving techniques.

I bought my mazda3 sedan a week ago and it went 240 km with half a tank. comparing this to my friend who got a 2002 protoge hatchback and that went 300km with half tank. reading the earlier posts i should be getting somewhere around 300kms too. so i am not sure if this is cause my car was at the dealership for a while and will improve in time or i should get it checked. fyi i am not a rash driver i take my time and dont floor my gas.

AVG fuel economy: 7.54L/100km or 31.3mpg. This from driving 100 - 110, occasionally 120km/h on the highway. Very pleased with the result, and I'm thinking that my car likes Shell gas better.

you guys should sign up for Fuelly.com. It does all the calculations for me and i can enter in the info @ the pump from my blackberry... I don't bother keeping my excel spreadsheet anymore

I just got my Mazda3, so I don't have any stats on it as yet...

I do both. Fuelly is good but I don't like how it rounds up. I like seeing more decimal places and being able to customize things that Fuelly can't do. However for some quick tracking it works well.

This is easily the best mileage I've gotten on a pretty much all-highway drive.
This was the route Hwy 401--->115--->Hwy 7--->417 for 389km. The trip computer read 6.6L/100km but real world calculations revealed it was 6.06 L/100km.
Mixed driving always gets me between 8-9L/100km

[jwei]

I get the worsttttt mileage, I'm going to start calculating my L/km, but just as a rough number I've been consistently filling up (from light going on to full, approx 50L?) and tracking the mileage, I get about 350-420 KM per tank. Mix of 50/50 highway and city I'd say.... Kinda depressing lol. Getting close to an oil change too, so maybe thats why?

Ya, I get pretty bad mileage. It's either because its still a new car,fast hwy driving (130km/h avg), or lots of city too

I've been driving exceptionally hard the last few weeks (4-6k rmp every shift) and I managed to get 325km out this tank.
Pretty bad considereing before this, the lowest fillup ive had was at just over 400km.
What can I say, i've got a heavy foot!

Pretty crappy mileage considering I havent driven this car hard yet. I'm gonna say its the cold drive commute in the morning and after work
