For mopeds, the engine oil should be changed every 300 to 500 kilometers during the break-in period, and every 800 to 1,000 kilometers after the break-in period. Here are some precautions for motorcycle riding: 1. Break-in period: During the break-in period, the riding speed should not exceed 50% of the maximum power speed, and the maximum speed should not exceed 75% of it. 2. After the break-in period: The maximum riding speed should not exceed 75% of the maximum power speed, as this may cause unnecessary malfunctions during riding. 3. Gear usage: Taking a common 125CC motorcycle as an example, 1st gear is only used for low-speed starts or climbing very steep slopes. Shift to 2nd gear immediately after starting. 2nd gear is generally used for speeds between 10-20, and 3rd gear is suitable for speeds between 20-40. 4th gear is suitable for speeds between 30-50. Generally, speeds above 40 can be driven in 5th gear.

As an experienced car enthusiast with years of repair experience, I've worked with many mopeds. Oil changes are crucial—typically every 1,500 to 2,000 kilometers or every six months, though this varies greatly with usage frequency and environment. In dusty areas or with frequent short trips, the oil gets dirty faster, requiring earlier changes. Checking is simple: a few minutes after stopping the engine, check if the oil level on the dipstick is between the high and low marks. Clear, bright oil is ideal; if it's black or has impurities, change it immediately. I've seen many engines suffer severe wear due to insufficient oil, leading to costly and time-consuming repairs. Make it a habit to check monthly, and choose the right viscosity—thinner oil in summer, thicker in winter. Synthetic oil lasts longer but costs more. Timely oil changes extend engine life, improve fuel efficiency, and ensure smooth, worry-free rides.

I've been riding my moped to commute for several years. My routine is changing the engine oil every 1,200 kilometers or so, especially since city traffic jams make the engine heat up quickly, and the oil consumption is high, so I change it more frequently. Doing it myself isn't difficult—just prepare a wrench and an oil pan, and spare a few minutes on the weekend to get it done. First, drain the old oil, replace the filter, then add the right amount of new oil. I once delayed it before, and the bike started sluggishly while burning more fuel—it was terrifying. Now, I keep track of the mileage to remind myself not to forget. Before every ride, I check the dipstick—if it's clear, I feel at ease. I recommend beginners start simple and not overcomplicate things. Choose a suitable brand of oil—don’t cheap out and buy random products. Regular changes make the ride smoother, and the engine noise becomes much quieter.

I take vehicle safety very seriously, so I never neglect regular oil changes for my scooter. It's recommended to change the oil every 1,500 to 2,000 kilometers or every six months, especially after long trips or during hot weather when more frequent changes are needed. Dirty oil provides poor lubrication, which can cause the engine to overheat and stall, posing significant risks while riding. I make it a habit to check the dipstick before each ride, and if the oil level is low or the oil looks black, I change it immediately. Keeping the engine running smoothly helps avoid breakdowns on the road—don't skimp on this small expense and risk bigger problems.
