| Winter/summer fuel are typically blended in a ratio suitable for the area where it is to be sold.

| That's probably right...maybe that's why I assumed we didn't get winter diesel here.

| i thought i read somewhere that they were only required to post bio diesel, we have been through 24 states here recently and ive never noticed a pump having that posted. "hot fuel" is sure becoming a big issue though, not trying to derail thread but its becoming a hot button issue in the cmv world which effects all diesel owner.
