Do New Energy Vehicles Need Lubricating Oil?
2 Answers
Whether new energy vehicles need lubricating oil depends on whether they are hybrid or pure electric. If it is a hybrid with an engine, then lubricating oil is required. For pure electric vehicles, which rely entirely on batteries, engine oil is not needed. Selection of Engine Oil: Naturally aspirated engines have relatively modest requirements for oil quality and can use mineral oil or semi-synthetic oil. If the owner has a higher budget, full synthetic oil can be used. Turbocharged engines, compared to naturally aspirated ones, have a more tightly constructed engine and operate under harsher conditions, demanding higher performance from the oil. They require oil with better fluidity, preferably full synthetic oil. Brand Selection: For the selection of lubricating oil brands, if long-lasting oil performance is a priority, Mobil lubricating oil can be chosen. If the focus is on the oil's engine-cleaning capability, Shell oil is recommended. For lubricating oil requiring strong oil film toughness, Castrol is a suitable option. For example, turbocharged engines are prone to carbon buildup during high-speed operation, so Shell oil with strong cleaning capabilities can be selected.
I've been driving electric vehicles for several years now. Back when I used gasoline cars, I often worried about changing engine oil, but now it's much more worry-free. Although there's no internal combustion engine requiring conventional oil, the reducer in the vehicle still needs gear oil for lubrication to prevent overheating and wear during high-speed motor operation. Bearings and transmission components also require grease application, which mechanics check during my bi-annual maintenance. The cooling system also involves antifreeze with lubricating properties. With fewer lubrication needs and lower frequency, it saves time and oil costs while making the vehicle more durable and reliable. Overall, new energy vehicles have fewer lubrication concerns, but key components still require attention. Regular maintenance ensures driving safety and stable performance.
