IMPORTANT: Treat fuel before temperature drops to O'C (32' F). For best results, use with untreated fuel. Follow all recommended instructions on label. REFERENCE ONLY Use John Deere TY22030 All Season Diesel Fuel Conditioner to treat Grade No. 2-D fuel if No. 1-D is not readily available during the cold weather season. NOTE: John Deere TY22030 Diesel Fuel Conditioner can also be used to treat No. 1-0 fuel. -Lower the pour point of untreated fuel from S' C (40' F) to less than -40' C (-40' F). Allowing the burning of Grade No . 2-D fuel year-round which provides more BTU per gallon than No. 1-D fuel and reduces fuel costs.
Engine block heaters (coolant) are an available option to aid cold weather starting. Use seasonal grade viscosity engine oil based on expected air temperature range between oil changes and a proper concentration of low silicate antifreeze as recommended later in this group. See ENGINE OIL and ENGINE COOLANT REQUIREMENTS later in this section. RG.23321.3 ·19·09MAY94 140497 PN=23 John Deere TY22030 Diesel Fuel Conditioner will: -Reduce the formation of wax to improve fuel flow through filters by reducing fuel gelling.
Seasonal Viscosity Oil and Proper Coolant Concentration MINIMIZING THE EFFECT OF COLD WEATHER ON DIESEL ENGINES Diesel Fuel Flow Additive Coolant Heaters Fuels, Lubricants, and Coolant 15 NOTE: On an average, Grade No. 1-0 fuel has a lower BTU (heat content) rating than Grade No. 2-D fuel. When using Grade No. 1-0 fuel you may notice a drop in power and fuel efficiency, but should not experience any other engine performance effects. Check the grade of fuel being used before troubleshooting for low power complaints in cold weather operation. John Deere diesel engines are designed to operate effectively in cold weather.
However, for effective starting and cold weather operation, a little extra care is necessary. The information below outlines steps that can minimize the effect that cold weather may have on starting and operation of your engine. See your authorized engine distributor or servicing dealer for additional information and local availability of cold weather aids. When temperatures fall below S' C (40' F), Grade No. 1-D fuel is best suited for cold weather operation. Grade No. 1-D fuel has a lower cloud point and a lower pour point. Cloud point is the temperature at which wax will begin to form in the fuel and this wax causes fuel filters to plug.
Pour point is the temperature at which fuel begins to thicken and become more resistant to flow through fuel pumps and lines. Use Grade No. 1-0 Fuel
