You should not add motor oil while the engine is running because the oil circulates throughout the engine when it is running, and adding oil while the engine is running can result in the oil not being distributed evenly. This can lead to improper lubrication of engine components and potential damage. It is recommended to add oil when the engine is off and cool to ensure proper distribution and lubrication. **

For a 125cc 4-stroke engine, it is recommended to use a high-quality, fully synthetic engine oil with a viscosity rating of 10W-40. This type of oil provides better lubrication and protection for the engine components, especially under high temperatures and heavy loads. It is important to check the owner's manual of the specific motorcycle to ensure the correct type and viscosity of engine oil is being used for optimal performance and longevity of the engine. **

To mix 2-stroke engine oil with another oil, you will need to ensure that both oils are compatible and have similar viscosity ratings. Start by pouring the recommended amount of 2-stroke oil into a clean container. Then, slowly add the other oil while stirring gently to ensure thorough mixing. It is important to follow the manufacturer's guidelines for the correct oil ratio to avoid damaging your engine. **

Oil has played a significant role in Nigeria's economy, contributing to a large portion of its GDP and government revenue. However, the heavy reliance on oil has also led to challenges such as corruption, environmental degradation, and economic instability. While oil has brought wealth to the country, it has not necessarily translated into sustainable development for all Nigerians. Therefore, it can be argued that while oil has been an important economic driver for Nigeria, it has not been a consistent or inclusive development engine for the country. **

It is not recommended to pour transmission oil into the engine as they serve different purposes and have different properties. Transmission oil is designed to lubricate and cool the transmission system, while engine oil is designed to lubricate and protect the engine components. Using the wrong type of oil can lead to damage and decreased performance of the engine. It is important to always use the recommended oil for each specific system in the vehicle. **

The motorcycle's engine expels oil through a combination of factors. First, the engine's internal components, such as the pistons, crankshaft, and bearings, create friction and heat, which can cause the oil to break down and be expelled as vapor through the engine's ventilation system. Additionally, the oil can also be expelled through the engine's breather system, which helps to release excess pressure and gases from the engine. Finally, any leaks or worn seals within the engine can also result in oil being expelled onto the exterior of the engine. Regular maintenance and inspections can help to prevent excessive oil expulsion and ensure the engine operates efficiently. **
