Gas (including Flex Fuel where fitted)
Most Chrysler Grand Voyager models in this family run on gas, including V6 engines such as the 3.3 V6 and 3.8 V6, plus the 2.4 16V in some applications. Oil change intervals can vary widely across years and engines, so treat the schedule as a range and prioritize the interval shown for your specific selection. Alongside oil and filter changes, pay attention to ignition and air-intake upkeep, as misfires and rough running are often tied to worn plugs, aged leads/coils, or restricted filters. If your Grand Voyager is a Flex Fuel variant (for example 3.3 V6 Flexfuel), keep an eye on drivability changes and fuel-system condition if the vehicle sees long storage periods or frequent fuel changes.
