I worked as a fuel laboratory technician in the military for 12 years. I was working as a lab tech when Low-Sulfur-Diesel (LSD) first appeared on the highways in the early 90's. I was called out many times that first winter to pull fuel samples from tractors that had stopped running on WY, CO, NE, and other western highways. Initial issues were fuel pumps burning up due to the lower sulfur content. The sulfur lubricated moving parts, so removal of sulfur caused fuel pump failures. The second piece of the puzzle was that managing wax dropout and chemical suspension in the LSD was more difficult. Wax would form in various places, most commonly the filters, and choke out fuel supply to the motor. The industry leaders were ill prepared when the first winter using LSD commenced. The issue was exacerbated even further when Ultra-LSD (ULSD) was mandated in 2006.
So it's been several years since ULSD has hit our highways, and the industry has done a much better job addressing the early failures. But the ASTM standard is very broad, so as any business goes, you only spend money on things that have the potential to increase profit, and fuel additives to go above and beyond the ASTM standard doesn't drive industry to absorb the added cost.
An in-depth rebuttal by Gary Pipenger, President, Amalgamated Inc (a custom blender of diesel fuel additives in Ft. Wayne, IN), based on a sampling of 35+ years of field and lab testing of fuel products, was submitted to refute an article titled "The Truth About Fuel Additives" that ran in Fleet Owner Magazine Aug 2012. The most important take away from Gary's information is in Point #5 where Gary says "These lab reports verify that nearly all delivered fuels sampled need some level of added winterization and/or upgrade chemical protection to insure adequate operability for the fuel use applications."
I always consider the quality of fuel from any individual source as suspect and take the extra measures financially reasonable to protect my investment. I change my fuel filters regularly and use an additive. A 64oz bottle of Howes ($17.99) will treat 160 gallons of fuel when temps are >0F (2oz to 5 gallons). I think that's reasonable to protect my $55K+ TV, so I don't mind paying the cost to be on the safer side of this debate.
