Should Yamaha Jog i use 95 or 92 octane gasoline?
2 Answers
The Yamaha Jog i has a relatively high engine compression ratio, making it more suitable for 95 octane gasoline. However, if the manual recommends using 92 octane or higher gasoline and there are no adverse reactions (such as noise or vibration) when using 92 octane, it can be used long-term. Here is the relevant information: 1. The difference between 92 and 95 octane: The Yamaha Jog i engine is more suitable for 95 octane gasoline. There is a certain difference between using 95 octane and 92 octane gasoline. Compared to 92 octane, 95 octane gasoline has a higher octane content. The higher the octane content in gasoline, the higher the octane value for the engine. 2. Choosing the right gasoline: Gasoline has different octane ratings and is classified into grades such as 90, 93, 95, and 97 based on the octane value. The higher the grade, the better the anti-knock performance. Cars choose different grades of gasoline based on the engine compression ratio. The manual for each car will indicate which gasoline to use. Mid-range cars with a compression ratio between 8.5 and 9.5 should generally use 90 octane gasoline, while cars with a compression ratio greater than 9.5 should use 93 octane gasoline.
I've been using my Yamaha Jog-i for over three years and have some insights about refueling. The manual clearly states that 92-octane gasoline can be used, so I've always filled up with 92. Actually, 95-octane can also be used, but it doesn't make much difference for this small-displacement scooter. 92 is about 0.5 to 0.6 yuan cheaper per liter than 95, saving me dozens of yuan on breakfast each month. Once, I chatted with an experienced mechanic at the repair shop, and he said that for low-compression engines like the Jog, 92-octane is completely sufficient, while using 95 might lead to incomplete combustion. The only thing to watch out for is avoiding small gas stations, as poor-quality fuel can easily cause carbon buildup. The money saved can be better spent on good engine oil, right?
