On runs at 50/60 mph I'm getting 49 mpg according to the read out, I'm happy with this but is it good or could it be better?
Thanks in advance

On the highway, yes, 49 MPG is good.

I get an AVERAGE of 7-8litres per 100Km. That's about 35MPG.

99% of fuel economy results are how the driver drives the car!

Better fuel economy can always be achieved but you will sacrifice performance and you may aggravate other drivers by driving slowly.

Seriously, to get the best out of your car, avoid stop-start traffic, unnecessary accelerating and speed. Service the car on a regular basis. Monitor condition of spark plugs.

I seem to remember that Ozvtr always drives with aircon on. If you use it that will reduce your consumption by a few mpg. If you get 49mpg with aircon on all the time that is good.

The old TU3 engines are not as efficient as more modern engines. They are pretty basic. The 35MPG is an average, stop start and highway. Of course I get much better highway economy.
Having said that I have found the 1.4 litre engine is under powered and I would sacrifice a bit of fuel economy for a bit more power.
HOWEVER I think the TU3 engine is great. It's the easiest engine that I have ever worked on!! :D
