2.4L and 3.2L Engines
This engine is designed to meet
all emissions
regulations and provide optimum
fuel economy and performance when using
high quality unleaded "Regular" gasoline
having a posted octane number of 87
as specified by the (R+M)/2 method. The use of higher
octane "Premium" gasoline is not required, as it will not
provide any benefit over "Regular" gasoline in these
engines.
While operating on gasoline with an octane number of 87, hearing a light knocking sound from the engine is not a cause for concern. However, if the engine is heard making a heavy knocking sound, see your dealer immediately.
Use of gasoline with an octane number lower than 87 can cause engine failure and may void or not be covered by the New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard starting, stalling, and hesitations. If you experience these symptoms, try another brand of gasoline before considering service for the vehicle.
