I'm hoping someone can help 'school me' on the status of current production diesel fuels in terms of types, quality and classification:
I just purchased a new 2015 F350 PSD
, and from what little I can tell, there appear to be no real differences or options in the diesel fuel widely sold at commercial fuel stations (i.e., the product appears to be the same at all dispensers). But back in the mid 90s, when I owned my last diesel motor (7.3L International), there were 2-3 different diesel products typically available at my local stations:
1. Fuel Oil #1: Premium-grade, less prone to gel at low temps
2. Fuel Oil #2: Regular-grade, somewhat prone to gel at low temps
3. Winter Blend: Designed for winter use
And so, my question is this . . . how has this changed over the years? In other words, is the single type of diesel fuel that is now being made readily available at most commercial filling stations a blend of some sort? Or is it the equivalent of the older Fuel Oil #1? Basically, what gives nowadays?
