SERVICING AND MAINTENANCE -> Engine Fluids and Lubricants for Your Ram Pickup 1500 Light Truck 2023

394 TECHNICAL SPECIFICATIONS  
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,  
the engine will have some or all of these symptoms:  
The MMT content of gasoline may not be indicated on the  
gasoline pump; therefore, you should ask the gasoline  
retailer whether the gasoline contains MMT. MMT is  
prohibited in Federal and California reformulated  
gasoline.  
GASOLINE/OXYGENATE BLENDS  
Some fuel suppliers blend unleaded gasoline with  
oxygenates such as ethanol.  
Operate in a lean mode.  
OBD II Malfunction Indicator Light on.  
Poor engine performance.  
CAUTION!  
FUEL SYSTEM CAUTIONS  
Poor cold start and cold drivability.  
Increased risk for fuel system component corrosion.  
DO NOT use E-85, gasoline containing methanol, or  
gasoline containing more than 15% ethanol (E-15).  
Use of these blends may result in starting and  
drivability problems, damage critical fuel system  
components, cause emissions to exceed the applicable  
standard, and/or cause the Malfunction Indicator Light  
to illuminate. Please observe pump labels as they  
should clearly communicate if a fuel contains greater  
than 15% ethanol (E-15).  
CAUTION!  
CNG AND LP FUEL SYSTEM  
MODIFICATIONS  
Modifications that allow the engine to run on Compressed  
Natural Gas (CNG) or Liquid Propane (LP) may result in  
damage to the engine, emissions, and fuel system  
components. Problems that result from running CNG or LP  
are not the responsibility of the manufacturer and may  
void the New Vehicle Limited Warranty.  
Follow these guidelines to maintain your vehicle’s  
performance:  
The use of leaded gasoline is prohibited by Federal  
law. Using leaded gasoline can impair engine perfor-  
mance and damage the emissions control system.  
An out-of-tune engine or certain fuel or ignition  
malfunctions can cause the catalytic converter to  
overheat. If you notice a pungent burning odor or  
some light smoke, your engine may be out of tune or  
malfunctioning and may require immediate service.  
Contact an authorized dealer for service assistance.  
Problems that result from using gasoline containing more  
than 15% ethanol (E-15) or gasoline containing methanol  
are not the responsibility of the manufacturer and may  
void the New Vehicle Limited Warranty.  
METHYLCYCLOPENTADIENYL  
MANGANESE TRICARBONYL (MMT) IN  
GASOLINE  
MMT is a manganese-containing metallic additive that is  
blended into some gasolines to increase octane. Gasoline  
blended with MMT provides no performance advantage  
beyond gasoline of the same octane number without  
MMT. Gasoline blended with MMT reduces spark plug life  
and reduces emissions system performance in some  
vehicles. The manufacturer recommends that gasoline  
without MMT be used in your vehicle.  
DO NOT USE E-85 IN NON-FLEX FUEL  
VEHICLES  
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline  
containing up to 15% ethanol (E-15). Use of gasoline with  
higher ethanol content may void the New Vehicle Limited  
Warranty.  
The use of fuel additives, which are now being sold  
as octane enhancers, is not recommended. Most of  
these products contain high concentrations of meth-  
anol. Fuel system damage or vehicle performance  
problems resulting from the use of such fuels or addi-  
tives is not the responsibility of the manufacturer  
and may void or not be covered under the New  
Vehicle Limited Warranty.  
NOTE:  
Intentional tampering with the emissions control system  
can result in civil penalties being assessed against you.
