Re: 6 liter and ULSD - interesting observation
Truck appears to have dropped about 1/2mpg, down from 13.5-14 to 12.9/13.4, but winter fuel has always lost milage. Been tracking ULSD since October 06, still running DS with each fill up. Truck appears to be running quieter, with no loss of performance. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
