Steve: So true. Winter diesel (blended diesel) never has given us the same miles per gallon as #2 (summer diesel). Not only that but this ULS diesel gives even less. Had the opportunity to get some LSD (neighbor filled up in Nebraska and it was the wrong stuff for his truck so I bought some of it off of him as he purged his tanks). Got over 22 MPG on that particular tank full - same run - from Manhattan to Salina and return, neglible winds (under 20mph here in Kansas is calm as you know
) and driving 60 to 65 solo. What was amazing is I wasn't getting passed by that many vehicles!!
