280zx Fuel Consumption

[Aussie260z]

Hi Guys, was wondering if i could get some help with my 280zx,

I have a problem with the fuel consumption,

Im getting roughly 330km's (200miles approx) out of a tank, roughly 65Litres of fuel,

That seems kinda rough to me,

Ive had a bit of a look around and other folks have said they are getting (or its possible to get) out of an L28E atleast around about the 20mpg's mark, which would give me in-access of 500km's out of a tank by my calculations,

The car runs really well, starts first time, dosent seem to be miss-firing,

Anyone got any theories on what could be leading to this kind of fuel consumption???

You might need a new set of fuel injectors. I replaced mine on my 76 280Z at about 200,000 miles and my hiway gas mileage increased from 19 mpg to 24 mpg.
