My mileage has been inconsistent since I purchased my 2005 CRD in July. On its cross-country journey from ME to CO, I averaged between 17-22 MPG with skis and a bike on top, trying to average 78 MPH east of the Missouri River and 83 in NE and CO. Here at altitude (5400 feet), my most recent tank netted me 304 miles of pure city driving and quite a few cold starts (multiple cold days off). As I increase my distances this spring, I'm expecting to get closer to the 20 MPG I was experiencing with a 60/40 city/highway driving ratio. I consider 400 miles per tank a good yield.
A few other notes, I have noticed a decrease in fuel efficiency since the introduction of ULSD. My previous vehicle was a 2005 VW Jetta TDI Wagon (which I literally tore apart in ME, hence the Jeep), and its economy suffered after the introduction of ULSD. Also, our warranties limit us to B5 bio, correct? Here in CO, B20 is the standard retail blend, but I got a bit of flack from VW for using it in my Jetta. Any experiences with Jeep "towing" the official company line in regard to bio-percentage?
Thanks! I just found this forum, this is my first post and I'm very excited to keep reading!!
