I kind-of interested of what others are getting! When I bought the wife a used 09 G6(2.4 Sedan) w/48900 km, the car was getting 12.6L/100km. Now that we had it for a few weeks(1200km) its dropped down to 10.7L/100km. This is all city driving so far!

don't know whats up with the first post?? :confused:

I'm getting anywhere from 7.8L/100km to 8.2L/100km with cruise set at 120kph on the highway. It usually sits at a little over 2000 RPM.

Devriesd- yours is a GT, so I'm guessing its a 3.5....right? Do you know what GM lists my 09 G6 w/2.4 at on city L/100km and highway L/100km.

Thankx, Paul....EOA Baby!

Sorry I have no idea. For my car I was just going off what the display said, I have no idea how accurate it is either.

I get around 8.0L/100km highway and 100% city driving I can muster 12L/100km without taking it easy on the throttle. It's fairly good overall, I use the auto/stick selector quite a bit as well to try to keep the engine on boil for whatever might arise. The 3.5L V6 holds its own. I try to keep rpms in town around 2400-3500 as it seems the engine is in it's glory. I've never really checked to see what my engine turns at 110km/h, but I rarely drive it over that.
