Should the Land Rover Range Rover use 95 or 98 octane gasoline?
2 Answers
Land Rover Range Rover uses 95 octane gasoline. Inside the fuel tank cap of the Range Rover, you can see the manufacturer's recommended gasoline grade. Simply follow the manufacturer's recommendation when refueling. Differences between 95 and 98 octane gasoline: The difference between 98 octane and 95 octane gasoline lies in the octane rating and anti-knock performance. The gasoline grade represents the octane rating of the gasoline. For 95 octane gasoline, the isooctane content is about 95%, and the heptane content is approximately 5%. Since isooctane has better anti-knock properties and heptane has poorer anti-knock properties, a higher octane rating indicates better anti-knock performance of the gasoline. By extension, 98 octane gasoline has even better anti-knock performance. Precautions for refueling: Although 98 octane gasoline is superior, it is not suitable for all vehicles. Generally, vehicles with fuel tank caps labeled "Please use 95 octane or higher gasoline" can use 98 octane gasoline. Additionally, vehicles with an engine compression ratio of 10 or higher are also suitable. Owners should avoid frequently changing gasoline grades. Once a suitable gasoline type is chosen, it is best to stick with the same type for the long term.
I often work with Range Rovers at the repair shop, and this vehicle performs best with 98-octane fuel. Its engine has a high compression ratio, and using lower-grade fuel can easily cause knocking, which may damage pistons and cylinders over time. The manual states that 98-octane is the minimum requirement, while 95-octane is barely acceptable but strongly discouraged. Especially when frequently climbing hills or driving aggressively, 98-octane fuel provides better engine protection. I've had clients who opted for cheaper 95-octane fuel long-term, only to spend over 30,000 yuan on engine repairs two years later. Remember to regularly clean carbon deposits from the fuel system. Nowadays, 98-octane fuel is widely available at gas stations—don't skimp on this aspect of vehicle maintenance.
