fuel consumption

Curtis · #1 27th July 2011, 12:15 PM

i dont know if this is normal or if i can improve on it but i use about 10 liters of fuel just driving to work and back everyday which is only about 50km.
i am due for a service but just seems too heavy on fuel.
it also will cut out very soon after the petrol light comes on.
might be normal im not sure just thougth maybe something is blocked in the complex tank or something is not right.

Howzit bru? Thats me talking SA. If the converter i've used is right (yeah i needed one of those) so it's basicly 31 miles and 2.6 galons. So just over 15 MPG so not great but 15 miles each way and cold start up it might not be far away. Hard to tell with short journeys.

Give her a run up to Empangeni and back and see what she'll do on a run

I'd say that's about normal in stop start traffic, but couple of other variables like driving style, temperatures for cold start, load from accessories etc.....

If I fill mine up with less than 100 miles range showing on the tank it'll only take about 70 litres - if I wait till the light comes on it's nearer 80, but still nowhere near the 90 litre capacity.

i have gone to empangeni few times and get very good consumption.
it could be due to temps between 9 c and 13 c in mornings and the 25km trip to work which is causing bad consumption.will see after the service if it comes right.was hoping there was a issue with something that i could fix to get a good fuels consumption.

is everyones fuel gauge inaccurate when it calculates the milaege that can still be covered or is it just mine because the polo i have seems to be very accurate yet the a8 will tell me i can do 40kms but it will cut out down the road.

Mine is the other way. When it says I have no fuel, I can still keep going. I think I've heard similar from other '8 drivers

When mine reaches '0' on the trip computer, I have two gallons left in the tank. Which suits me fine as I know I have a margin of error and I'll avoid thrashing the engine when there is a possibility of the fuel supply failing, leaning off the mixture and trashing a piston.
