Guage is not particularly accurate - mind you, the loud pedal is being pressed on yours - 210 to a tank is lower than "average" 250

I think it has probably got something to do with a recent decat and vta dv. Still you only live once. Tell you what, the Scooby exhaust note has got to be in the all time top 10 for cars.Better sound than any v8.

exactly the same sypmtoms as mine too (MY02) - the first half of the tank lasts for about 150 miles, the rest just seems to fall out the back or something

personally I think the guages have been designed wrongly, that's all

Probably find that the fuel tank is not box shaped, so when the fuel level in the tank has dropped to 50% there may only be 40% of the total capacity left.

Maybe if Subaru removed the prop shaft there would be more space under the car to put a regular shaped fuel tank in so the fuel gauge will drop in a nice linear way.

Though saying that no car I have owned has had a linear fuel gauge, not sure I would want empty on the gauge to actually mean that.

Thumbs down

I was going to say that. The bottom half of the tank is smaller than the top half

I've never had a car with an accurate fuel gauge. It's not rocket science though is it? It's not as if there's a mechanical linkage between the tank and the gauge, all you have to do is interpret the elctronic signal in a non-linear way.

This is one area where motorsport technology could usefully trickle down to road cars. F1 and rally cars have very accurate fuel gauges, witness Sebastien Loeb on the Turkish rally. Why can't we have these on road cars?

How about fitting a tow bar and pulling a tanker full of SUL fed straight into the Scoobs tank, much less stops, no more 210 miles to a full tank, problem solved lol

managed to get 180 out of the first half and 145 out of the 2nd half(total 325). I was going nice a steady this week (65 mph average). My normal average is about 280 though

It really is just the fuel gauge not being very linear across the scale. My MY94 STI is just the same but with a smaller tank, and less miles of course.

yeah, my MY93 is the same, filled up the other day, looked at guage, it was halfway between full and 3/4 at 83 miles. By 105 miles it was just above 1/2

I get 210 miles out of a tank in mine, but I only have a 50 litre tank

I have a 30km drive to work (take the kids to school first) and a 12km return trip. Never have figured out why I need to fill up at least twice per week, I just accept it

I think the counter is wrong as well...keeps telling me I'm doing over 1000km a week but maybe my maths is all wrong as 30+12 = 42. 42x5 = 210km per week.

Oh, I forgot, that'll be the 800km of blasting it

As above.Get 140 miles to the first half of the tank,taking it steady. Then the rest just disappears. Is this just a dodgy fuel guage? or is there another explanation?
