Can the Cayenne use 95 octane gasoline?

The Cayenne can use 95 octane gasoline. Official data indicates that the Cayenne should use 95 octane or higher gasoline. 95 octane gasoline consists of 95% isooctane and 3% n-heptane. When the engine has a high compression ratio, high-octane gasoline should be used. If low-octane gasoline is used in a high-compression engine, it may cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving performance. The Porsche Cayenne is an SUV model with a length of 4846 mm, a width of 1939 mm, a height of 1705 mm, and a wheelbase of 2895 mm. The Porsche Cayenne is equipped with a 4.5-liter V8 32-valve all-aluminum naturally aspirated engine, delivering a maximum power output of 340 horsepower and a top speed of 266 km/h.
I personally think it's acceptable to temporarily use 95-octane gasoline in a Porsche Cayenne, especially when you're in remote areas where 98-octane fuel is unavailable. The Cayenne's engine is designed with a high compression ratio, and 95-octane fuel has a slightly lower octane rating, which might occasionally cause minor knocking—that rattling sound—but this won't immediately damage the engine during short trips. However, long-term use is different: it could reduce power output, slightly increase fuel consumption, and even lead to carbon buildup issues, raising maintenance costs. I once tried 95-octane in a friend's Cayenne and noticed the acceleration felt a bit sluggish, so sticking to the manufacturer-recommended 98-octane is the safest bet. Don’t cut corners in daily driving—the manual clearly states that in emergencies, you can use 95-octane but should switch back to higher-grade fuel as soon as possible to avoid engine damage.
