The Mazda 3 Fuel Economy Thread
« on: June 16, 2007, 09:32:27 AM »
To save us taking the fuel computer thread off on a tangent, feel free to use the same or different details but you get the idea:

Car: 1.6 TS Manual
Reg: 06
Mileage: 12000
Normal Driving: Commute = 17 miles each way - 5 miles rush hour urban, 12 miles rush hour motorway, some sub-urban trips <10miles, occasional longer trips

All calculated on a tank by tank basis

Average MPG: 35.0
Best MPG: 45.2
Worst MPG: 30.6

TS2 - 1.6 diesel (regd 56)

Only 5,000 miles on the clock  - about 60% of my mileage is local around town (round trips of about 10 miles) - with occasional  250 mile stint.

Fuel consumption (current) - 52 mpg (both computer and brim to brim checks). It was just shy of 50 mpg when I bought it (2,300 mls on the clock).

Does not seem to be a lot of difference between the consumption on local or longer journeys.

Whats your oil consumption like?

If its still heavy that would indicate your engines gonna take a while a longer to run in. My Golf diesel only ran in till about 25K. But thats 'cos the previously owner granny'd it too much!

Oil consumption negligible - I did put about 250ml last week but according to the dipstick it barely needed that, and that was the first oil I have put in since having the car (2,700 miles ago) and I suspect since the car was made.

The oil I used was Castrol Magnatec  - I couldn't see anything in the owners manual about what type of oil to use (standard, semi-synthetic, or synthetic).

Just had my car serviced and I've lost 2mpg (nearly 6%) :(. I think its because they reduced my tyre pressures at the service - I've been using 3-4psi above the recommended to improve the mpg and not noticed any uneven tyre wear.

Not had to put any oil in my 1.6 petrol over the first year although it did drop to about halfway between min/max on the dipstick. All changed now.

For those that might be interested, having just done a 2,000 mile trip mostly on Motorways in France I thought these figures might be worth publishing.

Ltrs                   274.19
Galls                   60.32
Cost                £261.06
Average MPG        34.96
Total Miles          2022.2

One interesting set of numbers was for part of one leg of the journey From Millau to Paris
191 miles at a constant 100 mph (160kph) returned 33.67mpg. I was pleasantly suprised by that.

The car performed faultlessly and was admired by several people who actually came up and asked me about it.
I only saw 3 other Mazda3's during my entire journey so I guess they are fairly uncommon in France.

Some piccies available here http://www.mazda3forums.co.uk/index.php?topic=192.15 (Scroll down the page a bit)

I definitely get the 34-35 mpg average mentioned in 'What Car'. Mine's a '05 2.0. Great car, definitely one of the best value new cars on the market.  O0

Mike,

With relatively conservative driving (mostly motorway) we've cracked 400 miles (just) a number of times but this is really running it down to the wire after the fuel light being on for some time.

The car is a 2.0 Petrol Sport 5 speed Hatch and is a car I bought for my wife. Around town with her driving, she'll fill up after about 360 miles max, she doesn't like the fuel light on for too long... :D This is a pre facelift car and i think that the face lift version has a 6 speed? not sure.

Anyhow, not bad for a 2.0 petrol, the sedan may be a bit better because of less drag. However, both not as good as the diesel...

You have to be pretty conservative to get 400 as indicated by Danno ( Welcome to the forum by the way) 

I have a 2004 2.0 ltr Sport Saloon and a heavy foot. So on average I get 32 mpg. I never let my tank get to the point where the light comes on, but just recently I did a little experiment.

I filled up and then drove like a granny for the duration of the tank. After calculating this out I did 35.9 mpg and a total of 410 miles before the light came on. At which point I refulled.( I couldn't stand it any longer  :))

So the 400 mile barrier can be broken provided that 1. You dont like acceleration & 2. You never exceed 70mph.
However if this is the case then DONT BUY A SPORT MODEL  LOL .
The Zoom Zoom factor is just far too much fun to be conservative.

I got 32 MPG on a recent trip down to Gatwick and back which was very pleasing.

I tend to get around 27-29 MPG on normal running around.

I've got a new Mazda 3 2.0 D Sport

800 miles on the clock.

Currently getting about 42mpg (400-420) Miles per tank, computer thinks i'm doing 48-49mpg. Seems to be miles out. Does anyone know a reason for why the computer is so inaccurate?
