Is premium diesel science fiction?
Now that I have put away my old-tech Benz 300-D in favor of a 335d, I have been looking for premium diesel in the D.C. area.
I'll save you a lot of reading and just say that when I contacted a fuel distributor for BP/Amoco, he told me that the premium diesel line had been discontinued within the last two years, at least for BP/Amoco.
More interestingly -- and these are the guys who download the shipments at Curtis Bay in Baltimore -- he said that premium diesel is an "additivized product," i.e., it's just 40 cetane diesel with some gunk poured in, much as members on this forum do every fuel change but much against what my 335d manual recommends.
I guess I will feel better about dumping a little Optiube or Power Service in my tank from now on.
