RE thread on fuel consumption (http://discussions.fordforums.com/sh...t=fuel+economy)

I am gonna try to figure out my consumption.
<OL>
<LI>What is the neatest way of doing this?

<LI>If I slowly fill the tank up to the limit -to the neck- will it be actually be fooling me and leaking thru a anti-pollution overfill pipe to some catch tank or onto the ground?
<LI>The hand book says the "usuable" fuel capacity of the wagon is 72 litres. It also says there is a 10 litre fuel safety buffer to avoid running the tank dry (a warning light comes on the dash at empty tank +10 litres). So then, is the actual tank capacity 82 litres?
<LI>When trying to figure out the RANGE of the car on hwy cycle consumption (officially suggested to be 7.6 litres per 100km) I get 815km. My maths has got to be wrong there? Yeah?

<LI>On a 950 klicks drive yesterday involving city and hwy (A LOT of hwy) driving I got 523km from a slowly-carefully filled tankful, before the low fuel warning light came on. But I didn't note how many litres I put in at the fillup. Is it fair or poor or good?

<LI>Is my odometer reading falsely? I have 15" 205-65 tyres on a Falcon that originally wore 14" 195-75 tyres. The 15" has a radius of 315mm and the 14" has a radius of 305mm. I watched the speedo on one of those 5km speedo tests we have in NSW and the speedo regd 5.2km. Is this deviance acceptable?

</OL>
Thanks

Probably the best way to check your fuel consumption would be to fill your tank to when the pump clicks off do not overfill your tank. Go for your drive and refill your tank to the same point, note the amount of fuel used and calculate the consumption.

Just wait until the fuel light comes on (flat road) fill it up(taking note of how many litres you put in), and see how many kms you get until the fuel light come on again. Divide litres by kms and Multiply by a hundred and you'll get a reasonably accurate consumtion figure.
