Buy Shell, it's usually the best (better milage and least smoke, as a rule, over my cars). Other brands I don't have much experience with, since I almost always buy my fuel at Shell or the local CountryMark. The latter is 5% Biodiesel as a rule, and refined right down the road. Peter

It does happen in the current USLD era, especially with truckers. Diesel fuel in non-cold areas is rarely treated with anti-gel. Luther KB5QHUForest Park, IL '98 ML320 Max (171,xxx mi) On 9/29/2013 7:54 AM, Mitch Haley wrote: Used to hear stories of people fueling up in the south,

Probably just much better diesel fuel -- all those European engines require 50 cetane, and in the good old days of cheap diesel, you were very lucky if summer fuel in the US hit 30 cetane. Absolute crap -- that's why truckers always left their engines running, it was usually impossible to

Higher cetane index (ignitability) vs higher BTU content with lower ignitability. I have not noticed much of a difference, but then I've only been driving diesels for 17 years. Diesel fuel varies in BTU content and cetane index much more than gasoline, with quite a bit of it being fairly

I don't think we get seasonally blended fuels here, as it never gets that cold. Here in Michigan, it all comes from the same pipeline, the difference between brands is all in the additives, and all of it gets 10% alcohol except for some rare and expensive boat and snowmobile fuel pumps. What's

That is pretty much the point of top tier fuels. They pledge to meet specific standards (which everyone has to anyway) but also provide additives to the base stock that others do not. In other words, it's pretty much the same fuel you get anywhere, but it has additives that the manufacturers
