There are seven types, each with different qualities. Below is the relevant introduction: Motorcycle Engine Oil: Motorcycle engine oil is the abbreviation for motorcycle engine lubricating oil. Motorcycle lubricants typically include motorcycle engine oil (abbreviated as motorcycle oil), motorcycle gear oil, motorcycle shock absorber oil, etc. Lubrication Methods: Most modern engines adopt pressure lubrication. This involves adding an oil pump to the engine, using the pump's pressure to forcibly supply oil to various lubrication points. To simplify the engine structure as much as possible, pressure lubrication is generally used in combination with splash lubrication. For example, in an engine, the parts that truly use pressure lubrication are concentrated on the crankshaft journals, camshaft, and other components, while the small end of the connecting rod, cylinder, piston, rocker arm, etc., are lubricated by the oil splashed out after pressure lubrication.

Haojue motorcycle-specific engine oils are generally divided into three categories. The first is mineral oil, which offers high cost-effectiveness and is suitable for regular commuter bikes; the second is semi-synthetic oil, providing better cleaning and protection; the third is fully synthetic oil, with excellent high-temperature stability, ideal for motorcycles frequently used for long-distance travel or high-speed riding. Each type also comes in different viscosity grades, such as the common 10W-40 and 15W-50, suitable for both winter and summer use. Some high-end models even have specific oils for scooters and cross bikes, so it's important to check your bike type when selecting. By the way, their original factory oils feature the logo on the packaging, and buyers should look for the anti-counterfeit label when purchasing.

My previous Haojue 125 always used factory oil, and I remember there were four or five types displayed in the dealership showcase. The most basic one was the blue-packaged mineral oil, the silver bottle was semi-synthetic, and the gold-packaged one was the premium full synthetic. Different displacement models require different specifications—my little scooter only needed 10W-40, but my neighbor's DR300 required 15W-50. It's best to follow the manual's recommended oil change intervals: mineral oil around 2,000 km, while full synthetic can last over 3,000 km. The dealership mechanics always reminded me never to mix in automotive oil, as it could cause clutch slippage in motorcycles.

Haojue's specialized engine oils are quite finely categorized. I've seen three main types in the store. The mineral oil is suitable for daily commuting, semi-synthetic is for riders who frequently travel medium to short distances, and the full-synthetic excels in extreme operating conditions. The viscosity commonly includes the versatile 10W-40, while 15W-50 is recommended for particularly hot summer regions. They also have formulations designed for different engines, such as scooter-specific oil with anti-shake additives. The key to choosing engine oil lies in the API grade—Haojue's original oils are all SG grade or above, with a small round label on the side of the packaging indicating the grade.

Haojue's original engine oils are categorized into three types based on their base oil: mineral, semi-synthetic, and full synthetic. Mineral oil is the most economical but has a shorter oil change interval. Semi-synthetic offers a better balance in cleaning performance and longevity, while full synthetic provides the best resistance to high-temperature oxidation. The viscosity selection depends on the temperature. In northern regions, 10W-40 is suitable for year-round use, while in southern regions, 15W-50 is recommended for summer. Different models also have specific requirements: cross motorcycles are advised to use MA-standard oil to prevent clutch slippage, whereas scooters are better suited with MB-standard oil. All Haojue oil containers bear the JASO certification mark, which is more suitable for motorcycles than the API standard.

When selecting Haojue's specialized motorcycle oil, focus on two key dimensions: oil type and viscosity grade. There are three common base oil types - mineral, semi-synthetic, and full synthetic. Mineral oil suits light-duty riding, while full synthetic provides optimal protection for high-revving engines. For viscosity, 10W-40 is most commonly used, switching to 15W-50 in extremely hot weather. I've noticed they've recently introduced specialized formulas for urban commuting and long-distance touring - the former emphasizes fuel efficiency and cleanliness, while the latter focuses on high-temperature protection. Always look for the wing logo on the container when purchasing, and remember full synthetic oils can typically last about 1,000 kilometers longer than mineral oils between changes.
