Well unfortunately I have yet to fill it, but I filled up on side of a highway and then did a night drive from 9:30-2:30 so it was cooler at night, otherwise it's how ever the dealer had it tuned up. I haven't pulled any plugs or anything yet to see what it looks like. I'll try and get a pic of the DIC when it shows this km's on there, maybe this Tuesday coming up.

After putting in the transmission cooler this weekend, took it out on a 12 hour drive as well. Got a whopping 7.7 L/100 kms on the flat part of the highway, 8.7 with a little more load and rolly mins and 9.8 going up steep hills. The total DTE by the end was 630 kms driven.

I've done nothing but pop in a K&N replacement air filter and used some Bosch fine wire iridium plugs. Haven't even done the throttle body clean yet either.
Maybe I got lucky and the previous owner(first owner) broke it in good and so now I'm reaping the benifits of it.
I don't drive it to work, its more of a pleasure vehicle so for now its like 90% highway and 10%in city/drive to work.

Map Atlas Ecoregion Line World

Made that trip ALL in 1 tank of fuel going 1 way.
Going there my average according to the DIC, says between 7.5-8L/100 km, and on the way back (I don't ever see this happening) said DTE:860 km, but again, must be very rough estimate, otherwise on the way back was seeing 7-7.5L/100km. My receipts on fuel that I had got show me actualls of 8.78L/100Km, and on the way back 7.5L/100km.
