hammersley, If I had a camera I would have taken a picture of the sign at my local Exxon station, found it pretty informative. It had the cetane, pour and gel points for each product including dates. Red was the same as straight #2 year round. They also offered blend and straight #1, four hoses on each pump. There was a gal with tanker filling the tanks, I went over to ask if she had stirred up the tank by filling and talked for awhile. She said in the warm time of year they sold more red, once the winter comes it switches to the blend. After all it is a farming area, most people are broke. Per capita income in Montana is the second lowest after Mississippi, guess they're giving us a break by not enforceing the law.
