Just wondering if someone knows more about the winter fuel blend and mpg. I think its a 50/50 blend of #1 #2. not sure though. I will ask a local fuel shop. on a nother note i know that the diesel up here in alaska apears nothing like the diesel in the states. for the most part it is white and smell like karosene. I just got done doing a new o-ringed head and gasket so i figured while i was taking it easy i would check my mpg. Im geting about 12.5mpg -the correction factor for 285/75/16 tires. also what affect on ultimate hp do you guys think a winter blend has versus a #2.
