For a commercial vehicle these are good, what scares me is the amount of Sprinters that have so much rust on them, with only being a few years old. I know the Nissan NV vehicles aren't as fuel efficient, but maybe more than the Ford/Chevy vans? Not sure, can't find reliable comments on them, a 4.0L V6 says between 12mpg to 16mpg, seems strange to me
