Should the Panamera use 95 or 98 octane gasoline?
2 Answers
The official fuel grade for the Panamera is 95 octane gasoline. It is recommended to use the fuel grade specified by the manufacturer. The fuel supply method is direct injection, which fully complies with the National V emission standard. The differences between fuel grades are as follows: 1. The gasoline grade represents the octane rating of the gasoline. The higher the grade, the stronger the anti-knock performance. The price and octane rating of gasoline vary. 2. Gasoline grades are specified according to the standards of each country for petroleum products. Currently, there are three gasoline grades in China, which are classified according to the octane rating. 3. The user manual of each car will indicate the gasoline grade to be used. Cars with a compression ratio between 8.5 and 9.5 use 90 octane gasoline. If a high-compression engine uses low-grade gasoline, it may lead to incomplete combustion, resulting in a decrease in the engine's output power.
As a Panamera owner who has been driving this car long-term, I always use 98-octane fuel. High-performance engines like Porsche's are finely tuned, and 98's higher octane rating ensures more complete combustion, preventing knocking—especially during high-speed driving or rapid acceleration when power delivery is smoother. With 95-octane, you might occasionally feel slight engine 'hesitation' during spirited driving, compromising the experience. The manual recommends at least 95, but 98 unlocks the engine's full potential. Plus, long-term use of lower-octane fuel may accelerate carbon buildup, increasing maintenance costs. Having tested both in city and highway driving, 98 delivers quieter operation and better fuel efficiency. The extra investment in premium fuel pays off in driving pleasure and extended engine life—absolutely worth it. Make it a habit to check local gas station quality and stick to reputable brands to minimize engine risks.
