Fuel Selection
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, No. 2 diesel fuel meeting ASTM
specification D-975 Grade S15 will provide good performance.
If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is
required to operate at colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or dilute the No. 2 diesel
fuel with 50% No. 1 diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel filters.
This vehicle is fully compatible with biodiesel blends up to 5% bio-
diesel meeting ASTM specification D-975.
Chassis Cab models and
Pickup models configured with optional B20 capability, are
additionally compatible with 20% biodiesel meeting ASTM
specification D-7467 provided the shortened maintenance intervals
are followed as directed.
Diesel
Exhaust Fluid
Mopar Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that
has been API Certified to the ISO 22241 standard. Use of fluids not
API Certified to ISO 22241 may result in system damage.
You can receive assistance in locating DEF in the United States
by calling 866-RAM-INFO (866-726-4636). In Canada call
1–800–465–2001 (English) or 1–800–387–9983 (French).
CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic Additive
Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS.90032), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do
not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
