I put just under 90,000 miles on an 07 and never had a problem with it; never used a drop of oil. I had a Superchips tuner that had programs that would remove the V4 feature, but I never saw any point in removing it. It does save you some gas mileage, and does it without losing any power at all.

They had so many incentives in 2011 that I traded it for another one just like it. Only problem with it has been that the passenger side mirror will not stand up to be being backed into the carport wall.
