Probably not a fair comparison, as my van is an 09 (Gen 2). I've only had it for approx two months, but it seems to do much better than what I see up above. I have done an actual manual calculation from a fill-up to a fill-up. Mixed city/freeway, temps around 0 in the evening, 4 in the day. Result: 28.5 mpg. For city only, the little computer in the overhead shows around 24 mpg (converted to Imperial) and 36 on the freeway, again in Imperial.
