Well, like I briefly mentioned in the original post, in my case, the 42.4 mpg (US gal) figure includes extended stretches of 80+ cruising on hilly uncrowded US interstates as well as a somewhat aggressive 70-75 in traffic. Steve, I suspect you drive a little more sedately? Moreover, I've read that the TDI don't hit their stride mileage-wise until 20k miles so we'll see about that.
As was recently mentioned on tdiclub.com, 80 mph vs. 65 mph cost some TDI owners around 14 mpg. But put another way, how many cars get average 80 mph and still get in the 40s? And to think that I used to be happy with my much less peppy gasoline powered Honda Civic that got 33 mpg. (For our non-north american friends: 42.4 mpg (US) = 51 mpg (imp) = 5.5L/100km) Anyway, like I said, I'm going to try to document the changes from both boosting tire pressure and running BD. I'll keep everyone posted. -John '03 VW Jetta TDI 5-speed [EMAIL PROTECTED] wrote: >I have a manual TDI. I average 45 and do get almost 50 on the highway.
