Should the Jog i use 5w30 or 10w40?
2 Answers
The Jog i uses 10w40 engine oil. Below are the specific details of the Yamaha Jog i125: 1. Dimensions: The Yamaha Jog i125 is a scooter produced by Yamaha. Its length, width, and height are 1805*685*1050mm, with a seat height of 740mm, a wheelbase of 1275mm, and a minimum ground clearance of 115mm. 2. Engine parameters: The Yamaha Jog i125 is equipped with a single-cylinder, air-cooled, four-stroke engine with a displacement of 125ml, a maximum power of 6.1kw, a maximum torque of 9.7N·m, and a compression ratio of 11.0:1. It is paired with a V-belt continuously variable transmission.
I live in the north where winters are bitterly cold. I've been riding my Jog i for several years and always use 5W30 oil. The lower viscosity ensures smooth cold starts even in sub-zero temperatures, with quick engine lubrication and no gear dragging issues. If I do more outdoor activities in summer, I switch to 10W40 for better high-temperature protection. 5W30 also helps save fuel, making it ideal for city commuting with lower consumption, perfect for daily short trips. Always choose quality full synthetic oil—don't compromise on cheap brands. Remember, in cold regions, thicker oils like 10W40 become too viscous, making startups difficult and harming engine longevity. For regular maintenance, change the oil every 5,000 km to keep the system clean—safe riding is what matters most.
