Default Uh Oh!!

I just found this on Cummins website. Purely by accident mind you, but I think it fits in here nicely. I don't remember hearing some of this before! . . . .

Here is the link if you want to read more. There is a lot more there! Cumminsfiltration.com Brochures
Be sure to note the parts I 'marked up' in red!

Fuel Additives, Emission Related Chemicals, and Lubricity-Enhancing Filters
Most global emission regulations require a major reduction in the sulfur content of diesel fuels and emission levels from diesel engines. Fuel producers have created new formulations of diesel fuels with significantly lower levels of sulfur (typically less than 15 ppm). Often, these new formulations are also being combined with alternative fuels created from renewable resources such as biodiesel. These fuels reduce emission levels and consumption of petroleum.
The New Diesel
Low sulfur diesel fuel is cleaner burning and typically contains less than 15 ppm of sulfur. Under typical operating conditions, there should be no noticeable impact on overall power using low sulfur diesel fuel. Fuel economy may be reduced slightly because the process that removes sulfur also can reduce the energy content of the fuel. In some instances, the introduction of low sulfur diesel fuel to older engines may affect fuel system components or loosen deposits in fuel tanks. As part of a thorough maintenance program, customers should monitor diesel-powered vehicles closely for potential fuel system leaks or premature fuel filter plugging during the changeover to low sulfur diesel fuel.

Low sulfur diesel fuel has an increased wax content. The result of this increase could include higher cloud point (where first wax crystals form) and greater winter wax gelation, which is also likely to increase fuel filter plugging. Additionally, low sulfur diesel fuel has lower lubricity due to the refining de-sulfurization process. Lubricity additives are added at the fuel pipeline rack, however, lubricity additives sold in the aftermarket can be considered insurance to provide fuel system wear protection.
Biodiesel fuel is blend of petroleum diesel fuel and any fuel processed from a grain or vegetable, such as soy, canola (rapeseed), palm, cotton, olive, coconut, peanut, corn, etc. B2 blends (98% low sulfur diesel fuel, 2% biodiesel) actually add lubricity to low sulfur diesel fuel and help protect fuel systems. However, B5 – B20 low sulfur diesel fuel blends (formulations containing between 5% and 20% biodiesel) exhibit poor thermal and oxidative stability, resulting in premature filter plugging; have a higher wax content, which increases wax gelling; have a lower density and lower BTU value, which relates to 1 to 2% poorer fuel economy; and act as a solvent when initially used in fuel systems, resulting in premature filter plugging.
To provide optimal protection for the fuel system, Cummins Filtration® developed an innovative line of fuel additives, emission related chemicals and lubricity-enhancing filters.
Fuel Additives
As the engine’s key energy source, diesel fuel requires extra care to keep fuel systems operating at peak performance. Diesel fuel can contain organic elements, microorganisms, inorganic elements, and water, all of which can adversely affect fuel performance. In the past, natural sulfur content was a deterrent to this microorganism growth. The severely reduced sulfur content of low sulfur diesel fuel, however, allows more microorganisms to reproduce at a faster rate.
To condition the fuel system in extended service regimens, Cummins Filtration developed specific fuel additive packages and
field test tools that best meet customers’ specific operating requirements:
• Asphaltene Conditioner, for all-weather operations, improves filter performance by keeping organic contaminant in solution, preventing filter plugging and increasing fuel filter life. It also provides fuel stability and maintains fuel viscosity for better lubrication, improved fuel economy and injector clean-up.
• Winter Conditioner, for cold weather, prevents ice crystal formation/fuel line freeze-up and reduces cold filter plugging point and pour point.
• Turbo Diesel addresses all fuel concerns in one treatment, including pour point/cold filter plugging point, fuel line freeze-up, corrosion inhibition, and lubricity enhancement (currently only in the Continental U.S.).
• Microbicide, a dual phase fuel system preservative, quick-kills diesel fuel microorganisms, bacteria and fungi that can shorten fuel filter life.
• Fuel Tank Sampling Kit CC2523 uses a Bacon Bomb tool to sample the bottom of storage tanks where water is present to identify need for treatment.
• Microbicide Test Kit CC2524 bug alert test strips find aerobic bacteria, yeast and mold in #1 and #2 diesel fuels.
