Scooters (ladies' models) should use gasoline with an octane rating of 92 or higher. Here is some additional information: Considerations for refueling: The type of gasoline used in a motorcycle should match the engine's compression ratio. Generally, most common scooter engines have a compression ratio below 9.5:1, making 92-octane gasoline the most suitable for such engines. Guidelines for gasoline usage: The octane rating of gasoline does not indicate its quality or cleanliness. Using higher-octane gasoline in an engine with a low compression ratio may negatively affect combustion. Therefore, always use gasoline with the octane rating recommended for the engine's compression ratio or as specified in the manual.

I've been commuting on a small motorcycle for three years, and my experience is that 92-octane gasoline is the most suitable. Those pink scooters or retro models usually have the fuel tank under the seat, which can be opened with a simple turn of the key. Just choose the 92-octane nozzle at the gas station, and never touch diesel—last time my neighbor tried half a liter to save money, and the engine stalled immediately, costing hundreds in repairs. 95-octane fuel is more expensive but doesn’t perform much better; small-displacement engines can’t handle it well and it tends to cause carbon buildup. Always check the sticker inside the fuel cap—manufacturers always indicate the recommended fuel grade. A full tank usually costs around 20 yuan and can last about 100 kilometers, much cheaper than driving a car. When refueling, be careful not to insert the nozzle too forcefully to avoid spills and dirtying the bike.

Often helping my bestie with motorcycle issues, I've noticed many accidents involving wrong fuel. Ladies' motorcycles usually have a displacement around 100cc, and the manual clearly requires 92-octane unleaded gasoline. The fuel tank capacity is small, about four liters, and even when full, it doesn't run very far. Higher-octane gasoline can lead to incomplete combustion, and over time, the spark plugs get covered in black carbon. Some gas stations promote fuel additives, but they're actually useless for small vehicles. Always check the fuel grade before refueling; the green nozzle is the symbol for unleaded gasoline. In summer, don't fill the tank too full, as gasoline expands when heated and can leak out through the vent, easily damaging the seat cushion.

Having repaired hundreds of women's motorcycles, 80% of the malfunctions are related to fuel quality. You must use 92-octane gasoline; higher octane ratings will cause ignition delay. There are two types of fuel tank positions: for front-mounted tanks, turn the key to open the seat; for rear-mounted ones, use the key to open the side cover. Never believe in so-called money-saving tricks, like mixing diesel, as it will directly ruin the piston rings. Before the first of a new motorcycle, it's recommended to stick to a fixed gas station to avoid fuel quality differences affecting the break-in period. Observe the exhaust pipe—black smoke is a sign of abnormal combustion. Do not fill the tank beyond the filter screen at the fuel inlet, or it may leak on bumpy roads.

Compared the fuel quality from different gas stations, Sinopec's 92 octane is the most stable. Small motorcycle engines have low compression ratios, and higher octane fuel can actually cause combustion residue. If the fuel cap doesn't indicate the grade, check the owner's manual - it's usually printed in the section. Gas station attendants sometimes recommend 95 octane, but it's completely unnecessary to spend extra. A full tank costs less than 30 yuan and lasts about five to six days for commuting. Note that the metal fuel cap tends to rust, so regularly apply some rust inhibitor. If you accidentally fill with wrong fuel, don't start the engine - call a tow truck to take it to a repair shop for complete drainage, which can fix the problem.

Taught many girls refueling tips: First locate the fuel tank switch under the seat, turn the key until you hear a click before lifting the seat. Watch the fuel dispenser and press the 92-octane button, insert the nozzle fully for automatic cutoff - safest method. Don't skimp on gas, long-term half-tank usage accelerates fuel pump aging. Avoid recommended cleaners at stations - just take monthly highway drives to clear carbon deposits. Beginners often overlook fuel shelf life - if parked over two months, best to drain old fuel. Always lock the fuel cap after refueling to prevent theft and evaporation.
