Fuel Economy - What do you get out of a tank? (3rd gens only)

[HaydenVRX]

Why ?

much more torque means less throttle is needed to keep the car going. + best fuel eco is closer to 100 in a v8 where in a v6 its closer to 80.

Hayden, i cant see the most economical speed for a commodore being 100. At these speeds, air resistance and rolling resistance play the most crucial part. The boxy commodore will have a v similar air resistance figure to the 380 so the most economical speed for the commodore will be around 80-90 too.

Yeh they have more torque but that is because of the large capacity which needs more fuel to feed 6.0ltr, the most economical speed would be in the 60-80km range in most cars as their in top gear and pulling low revs with low wind resistance,

tj s2 vrx 5 speed auto. have just done over 2000kms in it (picked it up last thursday been driving it back from melb)
averaging at around 650km a tank on the highway
city and highway around 550km
mountains........ was around 15l per 100km wasnt driving it to rough
on the trip was averageing between 7l/100km to 12l/100km
so not to bad!
my manual 3L te did better tho redlined most its life and still gave me 450-500km to a tank. cant say it was babyed much....
