No doubt a dull subject at the best of times, but with petrol more than £1/litre again, worth a discussion.

 

Bought my Z NA a week ago and 180 miles later, thought I'd check the economy.

 

Pleasantly shocked to get 27.6 mpg!

 

This has included 50 miles in town (short, hard driving), the rest on the motorway.

 

Personally, I don't believe it even though my measurement technique is very accurate and I have checked my calculations again.

 

The reason I don't think it's right is:

 

- first week with a new car is all about familiarisation; over revving, hard acceleration, gear changing at the wrong time etc.

- town driving is very fuel hungry. My Mer E280 does 15mpg and a brand new company Vectra SRi I had did 22.

- the car has had many engine related issues (separate thread) which means that the car has spluttered, misfired and rocked it's way through the week.

 

I was therefore going to be happy with 20!

 

What do others get?

 

Pervez

well my TT auto does around 16-18 mpg around town/commute to work, but can get 26mpg on motorway cruise, so would seem about right.

 

What were your calculations to get this figure, what i do is basically brim to nearly overflowing, reset trip, giving me about 70 litres, run it down till the lights on, can do about 30 miles with it on, then refill it to brimming, noting how many miles and how many litres to fill it.

Dont trust the fuel light, its not accurate in when exactly it comes on each time. Its far better to fill it to the brim, do a certain amount of miles then see how much fuel it takes to fill it to the brim again.

I know my fuel light rather well, once managed to get 71 litres in the zed, which aint bad considering its a 72 litre tank :D

Guys - I think ur both saying the same thing and this is exactly what I do.

 

- Fill do brim;

- Do however many miles is appropriate;

- Fill to brim again and the amount you fill is the amount used.

 

BTW, what's the capacity of the Z NA tank?

72 litres

Thanks. So 400 miles is possible then...

I've done over 400 miles on one tank in mine (TT). It's also very easy to empty the tank in 200 miles though!

Agreed, mines stock and on average i just drive to work 14mile round trip and generally get 200-220 to a tank, still its a fun car and nissan werent to far from the truth on their official figures.
