Should the UY125 use 92 or 95 octane fuel?
2 Answers
Suzuki UY125 should use 92 octane gasoline. Suzuki UY125: The Suzuki UY125 is equipped with a 125ml single-cylinder four-stroke engine with a compression ratio of 10.3:1, so 92 octane gasoline is sufficient. Fueling precautions: Refuel in advance: Try not to wait until the fuel is completely depleted before refueling, as this can reduce the lubrication effect of the engine and affect its lifespan. Use reputable gas stations: Always refuel at reputable gas stations with high-quality fuel to ensure optimal engine performance and longevity. Avoid mixing fuels: Do not mix different types of fuel, as this can damage the engine and, in severe cases, lead to complete engine failure.
From a technical perspective, whether to use 92 or 95 octane fuel for the UY125, my personal experience is that 92 octane is perfectly suitable. This motorcycle has a compression ratio of approximately 11:1, and the manufacturer optimized it for 92 octane during the design phase. Using higher-octane 95 fuel doesn't bring significant benefits. Although 95 octane has better anti-knock properties and theoretically provides more stable engine performance under high load, the UY125 rarely encounters such conditions during everyday city riding. Over-pursuing higher octane is just a waste of money and may even lead to carbon deposits due to incomplete combustion. I commute with it regularly, always using 92 octane, and have ridden thousands of kilometers with smooth acceleration and fuel consumption maintained at around 2 liters per 100 kilometers—no major issues at all. If owners are concerned about fuel quality, choosing a reputable gas station is more practical than obsessing over octane ratings. After all, 92 octane is significantly cheaper, and the long-term savings can cover maintenance costs.
