RE thread on fuel consumption (http://discussions.fordforums.com/sh...t=fuel+economy
I am gonna try to figure out my consumption.
<LI>What is the neatest way of doing this?
<P><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?
<P><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?
<P><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?
<P><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?
<P><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?
