Hi folks,

i have a 1999 RB5 with full blitz nur-spec and hayward and scott downpipe, induction kit, Fuel pressure regulator, walbro pump and g-reddy boost controller....now i know these cars are hard to fuel and i dont think mines has gotten any harder to run since all these bits have been fitted, but im just wondering what sort of milage uz guys get to a full tank (60 litres). I can clear a full tank of super unleaded in 140miles with a good bit of 'fun' driving and in and around the towns, but wot sort of miles should i be getting driving normal, 50-60mph with no boost etc?? Any comparisons on the same spec of car would be greatly appreciated

 

Taking it easy, I get 220miles to a tank. Urban 20 miles to a gallon.
Giving it stick, 170miles to a tank, Urban 17 miles to a gallon

 

Ive managed 300 to a tank on my m99 uk turbo that was at a constant 4-4.2k revs.

I average around 240 to a tank which includes motorway and town driving.

Thats with 550 injectors,td05 16g, front mount,fse fpr blah blah

 

I usually get 200-250 miles to a full tank of v-power

 

My06 wrx gets 250 miles to a tank and thats kicking its ed in .20mpg round town havent took it far yet so dont know about cruising.

 

My STi 2 averages around 240 if i have alot of fun or upto 300 if im nice and steady. Thats with a 45 litre tank using tesco 99

 

Jez mines seems a little bad then The best iv got so far is 190 miles to £60/60 litres and that was totally dutering along like i was driving a micra)....aw i dunno, the car has been set up by a pro tuner over here in n ireland and he knows his stuff and it runs good. Im getting a haltec ecu, headers/up pipe, injectors and front mount shortly so hoping ill get it mapped to run a little easier....hope it doesnt get any worse or i dunno wot i'll do

 

Same here

 

hmmm funny that, i can only fit just short of 50litres in my tank

 

I get about 240-270 miles from about 50 litres, as that is when the warning light comes on, that is on a standard 2003 WRX, don't know if that is good or not as I have only had it a couple of months.

 

200-220 miles 95 WRX import!

Thats taking it easy on the last 1/4 of a tank!!

 

Yeah but ur car is a 1994 model and the earlier cars have a smaller tank!! The pre 97 cars have a 50litre tank, and the post 97 cars have a 60litre tank as far as i know....

 

LOL it would be a lot more straightforward if people could work out their own mpg between fill ups! Then tank size wouldn't make any difference would it. Mine will do 25mpg on a long run, 22 with a mix of commuting and caning it, below 20 on track. In other words, with a 60 litre tank, I'm happy if I get 300 miles out of it, it's tolerable if I get 250 miles. Any less than 250 and I'd be a bit upset, what with V-Power at 105p/litre or whatever it is at the moment.

 

Running a bugeye wagon with remap, decat centre, prodrive backbox, replacement filter.

On a full tank (driving it to virtually empty) I get around 340 to the tank. Probably around 270-280 miles before the fuel light goes on.

 

managed to get 323 miles on 48 litres of fuel before the light came on (was on dual/single carriageway )

 

mine is a 99 reg and ive never managed to get 60 litres into the tank and it has no warning light which i found out rather embarresingly even when it had cut out it only took 52 litres or somethin to fill the tank (including the 5 from the can) but when healthy i got 180 to a tank and with knackered o2 sensor 130

 

i average 240-260 from about 53-55 litres. have a warning light on my my99 uk turbo, so go from there. use it as a guide if im not near a petty station...

 

Same as you mate. Everyone loves coming on here after a question like yours to say that they can get 1000 miles per tank!!!

I never get any more than 200 miles per tank (early Classic). To get that I have to drive like Miss. Daisy..

 

yep same here .40 quid to fill it with tesco super and get 180 ish as a general

not worried what i get as long as i enjoy the drive

worse case i have had is 120 and best ever was 210 .

all on a 95 wagon full decat etc etc

 

I get approx 150 to a full tank,

03 Sti

 

I get about the same out of my P1 mate, but only because i have a heavy right foot! It all depends on how the engine is mapped, mapped for power or for economy(HA HA!!!)

 

the mapping can be both!
When cruising you're on a different part of the map compared to when you're on full power.
I use a lean mixture and high ignition timing when cruising, and rich mixture and low timing when on power.
I'm certain most maps use similar strategies. although not all mappers will take the time to really get the best out of the cruising conditions.
only when using performance parts like hot cams fuel consumption will suffer.
BTW I get 26 MPG on cruise and < 18mpg when flooring it
