Number 2 diesel fuel or dilute the Number 2 diesel fuel with 50% Number 1 diesel fuel. This will provide better protection from fuel gelling or wax-plugging of the
fuel filters.Fuel Selection — 3.0L Diesel Engine
Use good quality diesel fuel from a reputable supplier in your vehicle. Federal
law requires that you must fuel this vehicle with Ultra Low Sulfur Highway
Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum) to avoid damage to the
emissions control system. For most year-round service, Number 2 diesel fuel
meeting ASTM specification D-975 Grade S15 will provide good performance.
We recommend you use a blend of up to 5% biodiesel, meeting ASTM
specification D-975 with your diesel engine.
This vehicle is compatible with biodiesel blends greater than 5% but no
greater than 20% biodiesel meeting ASTM specification D-7467 provided the
