So im a bitt baffled with the following results and wondering if anyone can shed some light on this:

The car:
2003 Blobeye STI with PPP - No extra mods or remap

The facts:
In Uk i never get more than 300 miles per tank on a highway journey and i have to drive around 70mph to get these values. If i do 80mph average the consumption

In Europe, i consistently did around 200/210 miles per half a tank always on highway road and average between 80/90mph...That means around 400 miles per tank.

So the question is, what would be the reason for this?

I did noticed an increase of fuel consumption as soon as i entered back in UK so could this be connected that we being an island the air could be thiner or something?

Thanks

 

probably traffic conditions

 

As above. In France I can sit for long periods on cruise control, on, or off, motorways. I go places, don't see another car.

In the UK, cruise control is hardly ever used.

 

Or were being sold fuel which isn't what it says on the tin/pump. Regularly have to add NF to tank fulls of fuel that send the knock link berserk. Too much messing about by the fuel companies/garages trying to make a quick buck.

 

its a conspiracy man!!!!!

now you've had your paranoia moment,,, lol



i managed 35mpg average in my old 400bhp hawk on a long run down to bristol (160 miles).

i was sat tootling at 65mph all the way with no traffic issues and stopped once for a p1ss break.

If you have to slow down and then accelerate your mpg will be alot lower, as said it's all down to road and traffic conditions. Then there's also variations in road surface, newer surfaces tend to be quieter and smoother.

 

Knock link must be paranoid then try living in Armagh then see how you get on

 

Love the conspiracy theory but would go for the road surface theory as wouldnt consider traffic an issue as my numbers was obtained both in pretty much continuous runs without trafic interrupting me...Also, dont have cruise control...

 

I would agree with the traffic, barley used my brakes until in entered into a town.

 

Flatter straighter roads in Europe?
I noticed my fuel gauge going down much faster after it get's past the 1/2 tank level though, are you measuring exact quantities of fuel when filling up, or using your fuel gauge?

 

Just using my fuel gauge against miles covered...It definitely moved faster as soon as i entered back in UK but i see what you mean regarding the gauge moving faster after half tank...One of the Europe runs was from full tank to almost empty (Just before the reserve light comes on) and it did 390ish miles...In UK it gets almost empty when i reach the 290/300 miles mark.
