However, now the rest of the story.
The large refineries
must insure that at least 80% of their production is ULSD. However, in reality most, if not all of the large volume refineries are attempting to produce only ULSD. The small amount of LSD that is being produced (way less than 20%) is nothing more than fuel that does not meet the specifications for ULSD. It's simple production economics.
Furthermore, the distribution chain (pipelines, etc) has issues transporting both ULSD and LSD. The two cannot be mixed. The EPA has given the industry an additional 3 years to work out all the issues. You can be sure the industry will be switching over to 100% ULSD way before the EPA deadline. Monetary issues will force the switch quicker.
The bottom line is that LSD is going to become scarce in the very near future. It's price will increase accordingly. I predict that the only fuel you will find this time next year will be ULSD. It's simple economics.
The fact that LSD is still available in some areas is no surprise,
today. Tomorrow it will be a surprise.
BTW, none of the above applies to California where ULSD
is the only fuel that can be sold.
All of this has been discussed before and full information can be found at several web sites that have been posted previously.
Chevron Diesel and
The Clean Diesel Fuel Alliance are just 2 of the sites that contain this information.
