Probably too early to tell really. I don't drive a lot in general, so only have 5k on the odometer so far. And it had 2800 on it when I bought (dealer demo). That has mostly just been around town, dump runs etc. It has done one trip to Victoria from Nanaimo, and another from Nanaimo to Port McNeill - so technically pretty much the full length of the island. I have been keeping a log of fill ups and kms driven in between, but haven't sat down yet to do the math. Maybe I will this weekend. I don't expect it to be amazing, and didn't really buy it for economy. Of course that will be a bonus anything I can save there. Best I think I have hit on a single trip according to the dashboard summary is I think 7 or 8l per 100 km. But like I said, I need to sit down to calcuate the real world average. I mostly went Powerboost for on-board 7.2kw power, and the added torque and hp. Also, it was just the best overall deal when I was ready to buy. I looked at standard F15O as well, and the Chevy baby max diesel too.
