Default Taken back by the fuel economy

Just thought i'd post this on here as I was totally amazed at the economy recieved by a 380 mile round trip to Bristol earlier on this week in my WRX03.

All motorway, brisk driving keeping it below three figures but mostly near three figures . Stopped overnight and drove back the following afternoon.

43.20 litres to fill, and 300 miles to empty near the same point = between 28-30mpg. Fuel price 94.9. Fuel was Shell optimax.


TOP CAR IMO - Fuel economy is just a bonus

I drive a 350 mile round trip, Peterborough - Hereford and back, once a week. Mainly motorways with a bit of A-road at each end. I regularly get 28-29mpg cruising at 85-90mph.

It's a shame that I only get 18-20mpg the rest of the time.

MY04 Type25

My best four averages between fills (Optimax) have been 32MPG - a right old mix of roads and conditions with some boosty moments too - but no short journeys on cold engine. MY01 Bugeye WRX. Worst average has been 24MPG which includes larger ratio of shorter journeys. I think that Optimax gives a marginally better MPG so helps cancels out the extra cost per litre.

I managed to achieve about 17mpg average from a full tank with committed weekend driving. I always use optimax and find that it definitely gives better mpg. When driving the car normally on standard unleaded I am lucky to break 280 miles. When using optimax around 310 miles is the norm (lightly modified MY01).

cool, I forgot to mention, I had to fill up on the motorway services and the only fuel available was BP standard 95 unleaded which I had no alternative but to use. I couldn't believe how much it reduced the performance... for example when i briskley booted it in fourth the power died short of 5000rpm which was scary.

Re-filled with SUL now which is ace.

ScoobyTom... Type 25, isn't that the one with over 300bhp????... you are doing well to earn that type of economy if its the one i'm thinking of. Nice one dude.

ok i think ur figures are a little inaccurate! 17mpg is BAD! 310 miles from a scoobs tank is amazing! my 00 plate P1 gets around 200-220 miles from a tank (£40) and the mpg works out around 20-22.

No mate they are accurate. I use the car to commute to work where I usually sit at 70mph on the M25/M3 for almost all of the journey - off boost. I've read a post before where the owner stated they got 390 odd miles out of a Scooby tank and were gutted they couldn't break the 400 barrier (he was trying to win a bet).

As for the 17mpg - I don't think that’s bad when driving the car hard on B-roads. Peachy must be getting significantly worse than that and apparently single figure mpg's are possible on track days.


Think this all depends on driving style and the road type. Constant acceleration - brake - acceleration is going to drink fuel whereas steady off boost motorway cruising isn't obviously.

On the basis of 32MPG, I should be able to achieve 420 miles on a tankful. One day, I am going to try for 40MPG but it will be once only because the journey will be so boring - going no faster than say 60MPH and no boost, so under 2500RPM for hours. Somehow even doing this I doubt I would get even close to 40MPG.

I've managed to squeeze 30mpg out of my MY03 Sti Type UK on a run from Bristol to Stoke and back (steady 68-70mph) ... 30mpg in a WRX should be a doddle :P


...the trick is to slip stream milk floats and socialise with the cyclists

The two weeks' flood-control between fuel economy threads must be up.

Anyone for a "which oil"?

I seem to average about 280-300 miles to a tank. I use Optimax and generally drive 27 miles to work. Approx 75% is M1 motorway doing about 70-80.

I am assuming that is normal. Going to put some new Platinum plugs in this weeks, so hopefully this will help it out a bit.

I run a standard MY00 turbo wagon.

as yours' is a MY01 bugeye WRX/STi, the tank capacity is 60 litres, the low fuel light comes on when the tank has 10 litres left - but there is no reserve tank.

The only way to get 30+mpg from a WRX (MY01) is to stick below 3k rpm's at all times and don't take her above 77-78mph on the motorway.

There's no way doing just under 3 figures mph on the m/way will return 30+mpg....NO WAY!

As soon as it goes over 3k rpm's (77-78mph) they start guzzling fuel.

I've got an MY01 WRX and I can only get 50 litres in from 'dry' - not a 60 litre tank.......
