Hi I've owned my Impreza for about a month now.

I'm getting about 90 miles to £59 worth of fuel from town driving...

Not great! Someone said this works out about 9mpg. Anyway I'm planning my first long drive, up to Leeds...

It would be nearly 450 miles there and back. Working it out with the above stats it comes out to over £200 worth of fuel

But obviously I'd be getting better mpg on motorways rather than blasting around town. Can anyway give an estimate of what it would realistically cost?

Seems a shame to have to give up and get the train instead

 

Which impreza do you have?

my03 sti ppp I get 22 mpg on motorway for me, I regularly do a 160 mile trip mixture of motorway and A-Roads and it costs me £40 . I reckon a 450 miles trip would cost me about £120.

 

Seems you may have an issue there mate, depending on your car and mods. I have my96 wagon tdo5 and different ecu and get almost 100 miles for about £25 of shell vpower and thats town driving only..

 

I would have thought that you'd do the return journey comfortably in less than 2 tankfulls. Otherwise you have issues with your car that need sorting ASAP.

 

something defo not right. even if i hammer my car around town at license taking accelaration i would still get 180 miles to a full tank. on the motorway, sticking at 80 mph i get 300 miles to a full tank.

 

As above, something not right.

My classic running a 2.5 litre conversion and around 400bhp will do over 25 to the gallon on a motorway CRUISE and gets 22 around town.

 

07 Hawkeye Sti PPP, get about 250 miles to £45-50. Should think you've got an issue there.

 

well i got to glasgow to silverstone on 3/4 of a tank of fuel maybe a bit more, that was just a backbox,no other mods, not had to do the journey since me mods and remap to see what the difference now is

 

I managed to coax 34mpg on the Autobahn when heading to Italy by keeping the revs around 3000rpm but generally average about 25mpg.

I keep a record of the mileage and always fill up until the pump automatically stops. That way it's a fairly consistent way of keeping track of how much fuel the car is using because you know exactly how many litres you've just put in the tank and how many miles since last filling up.

So far in just over 50,000 miles it's cost me just under £10k!!!

 

When i bought mine, it was low and the light was on
Bug eyed sti
I filled it right up for the trip home
I set the trip at the Garage
310 miles door to door 300 miles motorway and 10 miles A roads
Kept it off boost virtually all the way and kept to a steady 65 - 70 mph
Got home on ONE tank £60

 

2007 STI UK WITH PPP GET ABOUT 20 ROUND TOWN AND USUALLY DO AROUND 190 BEFORE IT GETS TO THE QUARTER MARK THEN FILL UP WITH ABOUT 55 POUNDS oops just realised caps lock on sorry guys

 

I did inverness and back from Ni via troon and got around 650 miles out of just less than 2 tanks, if you do 60-70 most of the way, it makes a huge difference.

 

Something wrong there for £59 for 90 miles

Think the man next door must suck it out when you are sleeping

250 miles to the tank for the last ten years
Classic decatted mixture of town and fast short journeys
280-300 on a long motorway journey

 

As above

 

That's what I tend to get as well, 500 miles from 1.5 tanks so much the same

 

Op must be driving around town with 30ft flames shooting out of his exhaust I have gotten 9mpg on quarter mile days.

 

Okay, damn! Seems there might be something going on here then... by the way I hardly ever get to hammer it, 90% of my driving is just going to work and back, rarely get above 3k rpm!

Why do I own a Subaru lol? Maybe it's worth going on the long drive just a test of my tank

 

mate it sounds like your car is heavily over fueling and that will eventually cause engine failure I would get it booked in for a diagnostic ASAP.

 

Yep, i'd say 9mpg is about right there. I'd also say something's wrong with your car!

 

i have a classic import with an sti 2.5 conversion running 280bhp, it has a 3'' pipe de-cat straight through with a 5'' cobra end, hks mushroom and i only get about 100 miles round town on a tank, that lasts roughly 6-7 days that's with the wife driving it sensibly to work and me hammering it at weekends and one night a week.

 

When i had my03 wrxi got 400 miles out of a tank

Hull to newquay by the way with 2 adults 2 children and 3 suitcases in boot

 

Get a diesel, I got 56mpg on a run from kidderminster to malvern, thats not even motorway

 

9mpg is trackday mileage - think your car needs checking out!

 

you haVE a fuel leak lol

 

Don't say that, my last two cars did have fuel leaks! I can't go for the hatrick lol...

 

Just a quick update, got the train in the end lol. But done a full tank again and got 156 miles, does that sound more normal, or still a bit on the low side?

 

Motorways, low revs? What driving were you doing? Im assuming you've checked tyre pressure and basic tracking e.g. braking with hands of the steering wheel and checking for uneven tyre wear? When did it last have a service?

 

i travel from ayrshire to nottingham once a month and do it in just over a tank which is around 330 miles one way @80mph approx,

im running 355bhp in my07wrx so theres defo something wrong with yours,

 

Thats pretty good. I get 400miles per tank running 160BHP and travelling at 70mph. I would happily trade in double the power and traveling at 80mph for 70 miles less.

 

I reckon the op is really Petter Solberg.
