Hello All,
Is it recommended to use premium gas for Pacifica. For some engine types premium is recommended. Any idea what is recommended for Pacifica ?
Thanks

The manual should state but I'm guessing 87 octane is just fine. The octane of the fuel determines its pre-ignition or pre-detonation rating, meaning the higher the compression of the motor, the higher octane you need to avoid pre-detonation of your air/fuel mixture.

Some folks think premium fuel means premium mileage, premium clean burning, or a whole host of other things...that are all wrong. Use the cheapest fuel your motor was designed for.

From page 568 of the owners manual

These engines are 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.
