What grade of gasoline should a Volvo XC90 use?

[VanErin]

Volvo XC90 requires 95 octane gasoline. The fuel tank capacity is 80L. Introduction to gasoline grades: It represents the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Composition of gasoline: Standard gasoline consists of isooctane and n-heptane. Isooctane has good anti-knock properties with an octane rating of 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with an octane rating of 0. Selection criteria for gasoline grades: The primary criterion for selecting gasoline grades for cars is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles.

For luxury SUVs like the Volvo XC90, I usually recommend using 95-octane gasoline as its engine design is optimized for higher-octane fuel. While 92-octane is cheaper, it may cause engine knocking and accelerate wear, potentially shortening engine lifespan over time. Having driven several XC90 models, I've noticed smoother power delivery and more consistent fuel consumption with 95-octane. This is particularly important for turbocharged variants - higher-grade gasoline improves combustion efficiency, reduces carbon buildup, benefits the vehicle's performance, and is more environmentally friendly. If the manual isn't specific, check the fuel cap label which typically indicates 95 or 98-octane. Remember to inspect the fuel system during regular maintenance - spending a bit more on quality fuel is worthwhile compared to potential repair costs.

As someone who frequently deals with car maintenance, I always fill my XC90 with 95-octane gasoline. The engine requires fuel with high anti-knock properties to prevent detonation caused by insufficient octane levels, which could otherwise lead to premature spark plug damage. Although 92-octane is cheaper, it's not suitable for turbocharged engines, and prolonged use can increase maintenance burdens. 95-octane gasoline burns more completely and produces cleaner emissions. I recommend checking the fuel cap or manual instructions before each refuel to confirm the use of 95 or 98-octane fuel. Additionally, maintaining proper engine operation can effectively extend the engine's lifespan.

I always insist on using 95-octane gasoline for my XC90 because high-octane fuel helps reduce emissions and pollution. Although 92-octane is more economical, incomplete combustion can increase the emission of harmful substances in the exhaust. Using 95-octane allows the engine to operate efficiently and supports environmental protection. Check the manual or the label on the fuel tank cap to confirm if 95-octane is recommended. If unsure, opt for the higher octane rating. A simple habit like this can benefit both your car and the environment.
