Overwhelmingly BIO-diesel in Portland, Oregon
We're now in Portland, Oregon, having spent the past few days in Bend, Oregon. One thing I have really, really noticed here is the difficulty in finding PURE DIESEL. Just be aware that most stations...

B20 isn't as proliferated as people here make it seem. Yeah you can find it easy enough, but you typically have to be looking for it. By and large everything here is mostly b5. They typically advertise on the signs and pump when it is a higher mixture of bio above B5 (like B10, B20 or B99).
Low mixtures of bio are typically good for a diesel in that they reintroduce all the lost lubricity of diesel without hurting the emissions system, typically not hurting the seals and gaskets, and keep the entire fuel system clean(talking b2 to b5). In fact these low blends of bio are treated under the same astm spec as pure diesel since it's able to meet the same performance specs (d975), while higher mixes get a different spec (astm d6751 and d7467 for B100 and B6 to B20 respectively). So using the very low blend (up to B5) is pretty much a non-issue as it conforms to the same specs as full-petrol diesel. It is the higher blends that user should be aware of and are typically well branded and labeled. At least that's what I've found in the area.
Another side note. After a little bit of digging, I found that labelling is not required for blends up to B5 since it meets the same ASTM standard as regular petrol diesel. So that's why you won't see labels on the pumps in Washington and Oregon for up to B5 diesel
