Benelli BJ300GS requires 1.2-1.5 liters of engine oil. Function of engine oil: It serves as the lubricant for the engine, providing lubrication, reducing friction, assisting in cooling, and minimizing shock absorption. Composition of engine oil: Engine oil consists of base oil and additives. The base oil is the primary component of lubricants, determining their fundamental properties, while additives enhance and compensate for any deficiencies in the base oil's performance. Using lubricants can reduce wear on engine components and extend their service life. Engine oils in the market are categorized into synthetic and mineral oils, with synthetic oils further divided into full synthetic and semi-synthetic oils. Generally, vehicles using full synthetic oils have longer oil change intervals compared to those using semi-synthetic or mineral oils. Drivers can choose the oil type based on their driving conditions. The ratio of engine oil to gasoline can also be adjusted according to requirements.

I've been riding my Benelli BJ600GS (Golden Eagle) motorcycle for several years, and when changing the oil, I usually add about 1.8 liters. This amount isn't fixed; it's best to check the manual. Mine is the 700cc displacement version, and the manual recommends 1.8 liters. Before changing the oil, make sure the bike is level. After draining the old oil, slowly add the new oil while checking the dipstick—the midpoint on the scale is the optimal level. Adding too much oil is bad—it increases internal engine pressure, raises fuel consumption, and may cause leaks. Too little oil leads to insufficient lubrication and faster piston wear. I recommend using 10W-40 viscosity full synthetic oil, with slight adjustments for winter or summer as needed. Regular oil changes extend engine life—I typically do mine every 5,000 kilometers. Simple maintenance helps prevent major issues.

As a motorcycle enthusiast who loves tinkering, I've found through testing that the Benelli TNT 25's optimal oil capacity is exactly 1.8 liters. Its compact design and small-displacement engine have modest lubrication requirements - overfilling can cause foaming that impairs cooling, while underfilling directly leads to engine overheating and increased noise. When changing oil, don't just pour it all in at once. First use a funnel to add about 1.5 liters, then start the engine and let it idle for half a minute before shutting it off. Then top up the remaining amount to the midpoint on the dipstick. Both excessive and insufficient oil affect acceleration smoothness. It's best to perform oil changes when the bike has cooled down - it saves time and is safer. Long-term neglect of this can also burden the chain and transmission system, so regularly checking the oil condition is crucial.

My Jinjila manual states an oil capacity of 1.8 liters, with slight variations possible during actual refills. The oil change process is straightforward: after draining the old oil for about half an hour, add new oil while monitoring the dipstick marks—the center mark indicates the optimal range. Never overfill, as excess oil can spill, wasting resources and polluting the environment; too little oil may cause engine stuttering at high speeds. If you notice rapid oil consumption during daily rides, it could indicate leaks or oil burning issues that need prompt attention. Maintaining the correct oil level ensures efficient engine operation.
