Niagara Gazette — Fuel additives — There are many diesel fuel additives available, each formulated to give specific results. Some are intended as anti gel compound in cold weather and others for injector cleaning or cetane boosting. Check your owner’s manual or with your dealer regarding what to use for different conditions. Remember that additives are just a maintenance step, additives cannot solve foundational problems like massive carbon and fuel deposit buildup. This must be addressed with professional cleaning procedures using special equipment and industrial strength cleaners. Federal regulation requires that ULS (Ultra Low Sulfur) diesel fuel be used to lower tailpipe emissions. While this helps, it also lowers fuel lubricity and poses a wear threat to expensive injection pumps and cylinder walls. I recommend using a lubricity additive for this reason.
Injector maintenance — Injectors often foul over time, which affects proper fuel spray pattern and can lead to increased emissions and carbon buildup as well as negatively affect power and fuel efficiency. There are a number of professional injector cleaning fluids which will effectively clean your injectors if they are not too dirty. If too dirty, have the injectors removed and professionally cleaned. If injectors are heavily cratered or pitted from corrosion, they will require rebuilding or replacement.
DEF Replenishment — DEF (Diesel Exhaust Fluid) is a fluid that is used to complete the cleaning up of exhaust emissions. It is stored in a separate tank located under the vehicle. The DEF tank fill point is located under the hood in close proximity to other fluids that need periodic maintenance, check your owner’s manual to find the location of the fill point. Your vehicle will display a light on the dash indicating the need to fill the tank when the tank gets down to a certain level. DEF shelf life is typically at least one year, depending on the storage temperature. It is best stored out of direct sunlight between 12ºF and 86ºF. While DEF is not listed as a hazardous waste by the federal government, use proper disposal methods as it is a chemical. Do not empty into drains; dispose of this material and its container in accordance with all applicable local and national regulations.
Well, that should do it for special service requirements for diesel vehicles!
