Hi,

I introduce myself a week ago. I registered my scenic (vehicleid=838) and now I'm registering my megane (vehicleid=962) for which I'll soon have a first fuel log to enter.

The problem is to know the numbers I have to use for the EPA rating...

The megane is old and the FE is the old European test :
. Urban : 33.6mpg (7.0l/100)
. 90km/h (55.92mph) : 51.1mpg (4.6l/100)
. 120km/h (74.56mph) : 37.3mpg (6.3l/100)

Logically the "120km/h" test corresponds to your "EPA highway" while the "Urban" test corresponds to your "EPA city". If I keep the "90km/h" for your "EPA combined" then this one will be the bigest one which isn't logical.

Currently I exchanged the "90km/h" and the "120km/h" numbers, so I have :
. EPA city 33 mpg(US)
. EPA highway 51 mpg(US)
. EPA combined 37 mpg(US)
which is wrong because European highways are above 120km/h : 130km/h in France.

How can I estimate the "EPA combined" from "EPA highway" and "EPA city" ?
The average is giving 6.65l/100 = 35.3mpg.

Anyway, I will certainly be over 38mpg for the current tank while I was under 33mpg before hypermiling :-)

Thanks in advance,

Denis.
