Should a Porsche Use 95 or 98 Octane Gasoline?

[DelaneyFitz]

According to official guidelines, the Porsche Cayenne requires 95 or higher octane gasoline. Here is the relevant information: 1. The Porsche Cayenne can use either 95 or 98 octane gasoline. In reality, most regions across the country do not have 98 octane gasoline available. Higher octane gasoline does not necessarily mean it is better for the car. The octane rating refers to the gasoline's anti-knock properties and has no relation to its purity. Gasoline with better anti-knock properties has a higher octane rating. 2. To put it simply, lower octane gasoline (such as 92, 93, etc.) is easier to ignite when the piston is working, while higher octane gasoline (such as 95, 98, etc.) is relatively harder to ignite.
