Miles Per Gallon

How may miles do you all get to a full tank under 'normal' driving.

Pretty sure my petrol gauge is not 100% accurate and since fitting the immobiliser the low fuel orange light no longer comes on so I have to guess.

Think I'm about 300 miles before I refill.

Thats in an 89 S2
 
Almost 400 miles at 80/90 on motorways
In mixed city / A-roads, around 300 miles
About 120-150 miles on trackdays
 
944 t = 400 miles on a tank or 25mpg 1/3rd country 2/3rd dual carriageway/motorway
993TT = 340miles on a tank (90ltr)or 17mpg
 
I was consistently getting 350 miles on a circa 63ltr fill up (25mpg) before I fitted my Promax L2 chips now I get around 300 - 320 miles. The Promax L2 chips are rich though to provide a good safety margin. The best i've had is 410 miles out of 61 litres on a motorway run and had a bit which is just over 30mpg and that was a steady 90mph.
 
The Bull McCabe is quite a thirty bugger. I think around 20-22 mpg is what I get now.
I can't get used to the whole km per litre business.
While motorways are better for consumption I prefer to drive on what you call 'B' roads ?
Perhaps thats why I needed 2 cv joints this time around.
On a side notw, was out Kayaking at the beach last night, huge waves in the irish sea. Whats that all about. Great craic though. Roll on 5 and I'm off again.
 
'89 S2, like yours ... usually get between 310 and 380 on a tankful, although I don't run it to the point where the light comes on (I know the light works - I saw it once - but don't often run my luch that thin.) BUT this is with mostly town driving, which is very thirsty.

I have heard tales of 450-500 on a tankful ... which sounds lovely!

Hmmm...sounds like I'm way to low...or I actually have a lot in the tank when I refill...but I doubt it as its costing me £60 to refil at a time.

Apart from a heavy right foot could there be any other reason for this?
 
Heavy right foot / lots of inefficient (town) driving, both likely reasons.

I know that mine runs slightly rich, and leaning it off would help a little (it's something I keen on meaning to have done.) It was rich (but within tolerence) at the last MOT and at a rolling road session I did last year. Yours could be the same but worse, perhaps?

Mine is usually £53-£55 to fill, so you are about right there.

If you are really worried, keep a record of how much you put in (litres) and the milage at fill-up. Do this for a few months and you can work out the MPG accurately.


Oli.

(Another thing - if your odometer under-reads, you will appear to be getting poor MPG. Not sure how you test this tho'.)
 
944 T 230-260miles per full tank of mixed driving but I drive harder than most. I would use that as a road use minimum.

Regards,

Ben
 
Got my best and worst figures on the same weekend.

Best: 29.5 mpg

Worst: 13.5 mpg over 87 miles of the Nurburgring [:)]

Furthest on one tankful: 440 miles
 
On a steady run my S2 will easily get 400 miles before the light comes on, the Turbo used to manage about 350

.......it now struggles to get over 300 [:-]

BTW there are two gallons left in the tank when the light comes on so don't be scared to go low boys [:D]

Good effort Ben!! I like your style!
 
Consistently getting 28 mpg with the S2, bar an average of 16 mpg at Spa Francorchamps.
24 mpg with the turbo, easily falling to sub 20 mpg when properly using the right foot (Guru Racing 18 PSI chips).
Both are used mostly on dual carriageways/B roads and a bit of city driving.

(X L/100 km x Y mpg = 283, so 10 L/100 km = 28,3 mpg).
 
25mpg overall in the 944 lux automatic with Promax chip, about 3mpg progressing firmly uphill.:ROFLMAO:

The official figures in 1986 were 24.8mpg urban, 40.4mpg constant 56mph, 32.5 mpg at 75mph. That`s for the manual version of the car. The automatic uses more, except for the urban driving, when I get another...wait for it...704.4 yards further on a gallon (which is my contribution to the environment):rolleyes:

The tank holds about 80 litres, so a full tank from near empty should cost about £70+, so if your putting £50-£60 in, you`re nowhere near empty. When the tank is full you could get 769 miles from it. All you need now is 769 miles of road where you can drive at 56mph consistently for about 14 hours. Australia anyone?
 
Agreed,

I have got £75 in mine once mind you it was a motorway service station so the price is slightly higher.
 
Typical weeks MPG (mixture of driving to work in traffic and a run to night school on motorway) 26mpg

On a run 30-32mpg

best ever 36mpg, when I was restricted to 70mph due to tracking induced wheel wobble.
 
I get a less than frugal 150 miles from every £30 worth, thats about 21 mpg but its all short urban cycle type journeys.
 
I remember getting 18 miles per gallon when I first got LIL - finally did a long run and got 30ish MPG. Immediately stopped measuring.
