What grade of gasoline does the Volvo V90 use?
2 Answers
Volvo V90 uses 95-octane 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 with a high compression ratio, it may cause abnormal combustion, resulting in knocking, increased fuel consumption, and reduced driving power. The manufacturer of the Volvo V90 is Volvo (imported), and its classification is a mid-to-large-sized car. The dimensions of the car are 4959mm in length, 1879mm in width, and 1543mm in height, with a wheelbase of 2941mm. The body type is a 5-door, 5-seat station wagon, and the transmission is an 8-speed automatic with manual shifting capability.
I've been driving my Volvo V90 for three years and always fill it with 95-octane gasoline, as clearly required in the manual. Nordic engines are highly performance-tuned, and lower-octane fuel can easily cause knocking, with very noticeable piston slapping sounds. Last time at the gas station, I met a guy driving an S90 who said occasionally using 92-octane is fine, but long-term use can make the power feel sluggish and increase fuel consumption. I tried 92 once and clearly felt worse turbo lag, along with slight ticking sounds from the engine bay during acceleration, so I quickly switched back. Always remember to go to reputable gas stations—smaller stations often have lower-quality fuel with more impurities, which is worse for direct-injection engines. A precision machine like a Volvo needs careful feeding. Although 95-octane is more expensive, the smooth power delivery and long-term engine health make it worth it.
