I've discovered my 95 wagon already has a 255 fuel pump fitted as well as a blue panel filter and cat back exhaust system of unknown make. I've been told that this is this enough to increase fuel consumption over standard? Only getting 200 miles to a tank full or 300 if I drive like a granny, off boost.

Thanks

 

BTW it's a WRX import wagon I have

 

200-300 miles sounds about right for standard car. what makes you think theres an issue?

 

Just wondered mate.

 

ah righto, yeah sounds normal, there pretty hevy on fuel, mines about 300 driving like a ***** and under 100 giving it the beans lol

although there not as bad as evo's

 

Mine is normal then

 

sounds about right to me as well, dependant on driving style

 

Why do people fill their cars to the brim. That's enough to bring MPG down on it's own. Your carrying all that extra weight around.
If your on a long journey then fair enough but otherwise it's just crazy.

 

coz i can't be arsed to drive to the petrol station every couple of days to fill up!

 

Exactly

 

Fuel consumption will decrease if you fit a VTA dump valve.

 

What's a VTA dump valve then? It's got a Baily's one already fitted (came with the car)

 

Good point ive always thought that plus how can people afford too.

 

I think your safe

 

I get between 280 and 360

If you don't fill up to the brim you have to keep going back to the garage and that's wasted miles

 

Fair point im lucky and pass mine thats pretty good milage

 

a vta dump valve is vent to atmosphere, the loud noise old grannys hate when you change gear lol

 

I'm getting about 320 miles out of a 60 litre tank , which is around 25mpg

 

Tbho I don't ever think about MPG as its not a economical car full stop compared to anything nowadays.

 

All you with your massive tanks!

Mine is 45.5 litres.

 

My Scooby was bought as an economical car as my Alpina does 18mpg lol

 

Well I'll let you off then mate

 

I've worked out that I can get approx 26 mpg if I really drive like a Granny. I mean totally off boost and never go above 50-55 mph. I was putting it down to the WRX having really short gear ratios too. Normal?

 

I know the extra urbun is around 30mpg , urbun is 22mpg and combined is 24-26mpg. I got those figures from my owners manual. Mine is a classic and a P1 and the aero helps the mpg.
