    It should be in your owners manual. I would expect it to be either 89 or 91 Octane. By going down to a lower octane like 87 will reduce the performance of your van.

    Octane is a measurement of gasoline’s capacity to burn smoothly and evenly. The higher the octane number of the gasoline the more resistant it is to producing uneven combustion and the audible "knock" sound which, if allowed to continue can damage an engine.

    What is knocking? Spark knock is the sound of abnormal combustion. When combustion in a spark-ignition internal combustion engine is initiated by a spark, the flame front should fan out from the spark plug and travel across the combustion chamber rapidly and smoothly. If the last part of the air-fuel mixture ignites spontaneously (auto-ignites) before the flame front arrives, the sudden jump in the pressure in the cylinder creates the characteristic knocking or pinging sound. Knocking occurs because the octane of the gasoline is below the antiknock requirement of the engine at that moment.

    However, using lower grade should not cause any damage to your motor from knocking and pinging with lower grade fuel as your van should have a knocking sensor. You will lose performance and even your MPG will decrease with the use of the lower Octane.

    As well, if you use higher octane you are just throwing money out of your pocket. It will not increase your performance or even your MPG.

    Hope this helps.

    It's just a minivan - so probably just regular (87 octane). Check the owner's manual - it will tell you. Also, if you open the gas door, there is usually a sticker or "engraving" that states which type of fuel to use.

    Did it come with a owners manual? Check it or check with your local dealer.
