Fuel Sulfur Content
Fuel sold for use in diesel-powered engines for 2007 and later model year
vehicles may only contain a maximum sulfur content of 0.0015% by weight.
This was done to reduce particle emissions in the exhaust.
The use of ultra-low sulfur diesel fuel does not permit extension of engine oil
change intervals or oil filter changes.
Cetane Number
Direct injected diesel engines require a minimum cetane number of 43 under
normal starting conditions. Fuel with a higher cetane value may be required
for high-altitude or cold-weather operation.
Filtration
Fuel should be clean and free of contamination. Clean fuels should have no
more than 0.05% of sediment and water.
Fuel Additives
Fuel additives are generally not recommended or needed for fuels listed
earlier. Cetane improvers can be used as necessary. Biocides may be needed to
eliminate microorganism growth in storage tanks. In cold conditions,
treatment for water in the vehicle tanks may also be necessary.
Consult your fuel supplier about the use of additives to prevent
incompatibility among additives already in the fuel and the additives to be
used.
