So you haven't driven an STI? I have owned two STI's and now a WRX. And to be honest, on UK roads, the WRX is the perfect compromise. 0-60 in 5.5 seconds is not slow.

If you're at all concerned about MPG don't buy an Impreza. It's that simple.

Completely agree. It's crap and it will only ever be crap.

MPG is easily worked out. Not sure about the 3 gallon method though...

Zero your trip mileage went you fill up. Next time you fill up, divide the mileage by the litres added and then multiply by 4.55 and you have your MPG.

For example, 255 miles divided by 40 litres times 4.55 = 29.2 MPG.

See my early post fella.

I guess the 3 gallon guy always puts 13.635 litres every time!

When you consider the performance, the turbo, the fact that 4 wheels are driven etc I think that the MPG is fairly reasonable for Imprezas.

I used to have BMW 325ci sport and used the get 36 MPG out of that in a long run. In my impreza I got 33.9 MPG on a long run. Not bad considering it was powering twice as many wheels!

My Subaru is better then my Works can which is a Sprinter it only does on average 21MPG but I rag it everywhere from cold and couldn't careless about it lol.
I think I get around 25MPG on my Subaru but I couldn't care about MPG but the Impreza is the best car I've owned for MPG!

If I really need to not use so much fuel I just nick the fiancées Cupra FR that's revo'd running 210BHP and averages 50MPG haha

I fill it to the brim and get about 150 mixed motorway/ town miles until I need to fill it up again. I don't bother with conserving fuel or anticipate the road ahead other than to see if it's safe to let rip and get the back end out...

lpg! what a waste of money on an old wrx, the amount of miles you need to do for it to pay for itself is silly.

It isn't exactly a new discovery but common sense. I get 5-7mpg less doing the same journeys from the peak of summer to the coldest months of winter. Air is colder in the winter and therefore, more dense, so the car ecu throws in more fuel to achieve the correct mixture and prevent the engine from running lean.

Bloody good find that man!!!

I would have thought colder air would just mean more power at lower revs hence less throttle needed to cruise, funny how it all works.

I was obviously joking.

Back to the op, I would concentrate on servicing your car, using good fuel, tyres etc. The mpg will then take care of itself.

I asked how he put 3 gallons in when you can only buy and display it in liters

Also i feel obliged to ask again matt, What have you done to lose 135KG from your car apart from the aircon delete,Presuming you are calculating the kerb weight with appropriate fluids in at the correct 1395KG as you say its now 1260KG?

I wouldn't hold out too much hope. It amazes me how some people try to work out mpg. The correct way is so simple.

Yep fill it to the top, reset the clock...Drive it then fill it up again, See how much it takes and do the math with the miles on the clock....Simples.

What's the MPG for 400 miles and 46 litres of fuel? I don't do sums.
