Well...my thoughts are not quite unfounded but I certainly have found out alot about diesel and the Sprinter engine. The first thing is to never buy unbranded diesel. Second, diesel formulations can be different from state to state mostly based on the time of the year. During the winter it seems the major brands are selling #2 diesel which is fine as long as it's 15 ppm sulfur and not 500 ppm. Later in the year as the temps warm up there are a few states that require the #2 to be B5 or B20. I know this happens in Wisconsin and Minnesota while it seems that in New York and Michigan #2 diesel is sold year round. Federal regs require diesel pumps to be clearly labeled so we don't have to guess. My service station checks so far have shown only 25% of the pumps are properly labeled. #2 diesel and B5 don't seem to cause a problem. B20 on the other hand may.
For those who have never had a problem, that's great.
Sorry, a lot of this is MIS-information.
All on-highway diesel in the U.S. and Canada is 15 PPM sulfur and has been for close to a decade.
And, most pumps do NOT state bio content-- they state UP TO XX bio-diesel content. Just like ethanol-- neither pump labels nor clerks in the stations really know.
Branded/unbranded-- come from the same refineries. Just like batteries, a very few sources and quite a number of retailers.
Being from S Texas, can't comment on bio content winter vs summer.
