how many km can u do on a tank 4.2 and 2.8 guys please post
My unit converter tells me the S6 gets about 9.5km/L (22.5 MPG) on the highway. I intentionally don't calculate in town. The trip display says the average is 18.5 MPG, but that's optimistic I'm sure.
The wifes A6 gets at the very best, 11.5km/L (27 MPG) on the highway. In town, again going by the trip display it shows an average of 19.5 MPG, which I tend to believe.

I have a lead ish foot, and I usually average about 21 mpg, or 340 miles.
Lowest Ive seen is about 16 mpg, really stop and go, in winter, and about 260 miles.
A few "easy" trips have been around 30 mpg, or a little over 500 miles.

any sites u can think of that has rightups on 4.2 or 2.8? i am trying to learn more about them.
i just want one that is reliable so cant deisde if the 4.2 or the 2.8 is more for me..
so far the gas usage on the 4.2 is fine with me
Honestly, if your ok with the fuel economy of the 4.2, then I would say go that route. Enjoy the extra power and V8 goodness. And also, it seems that there are less issues with the 8, not as many valve cover gasket/cam seal issues for what ever reason.
