What is the difference between gear lubricating oil and engine oil?
2 Answers
The difference between gear lubricating oil and engine oil is: 1. Different working environments: Gear lubricating oil is mainly used in manual transmissions, reducers, and differentials; Engine oil is mainly used in automobile engines. 2. Different focuses: Gear lubricating oil focuses on protecting gears under high temperatures; Engine oil focuses on its fluidity at low temperatures. Gear lubricating oil, also known as transmission lubricating oil, is mainly made of antioxidants, antifoaming agents, and rust inhibitors. It can prevent gear surface wear and sintering, and comprehensively improve power transmission efficiency. Engine oil, also known as engine lubricating oil, can lubricate, clean, cool, seal, and reduce friction in the engine.
As someone who frequently goes on road trips, I've learned that gear oil and engine oil should never be mixed. Gear oil is mainly used in transmissions and differentials, where it has to withstand the intense friction between gears, so it's extra thick, like syrup, and contains extreme pressure additives. Engine oil, on the other hand, circulates daily inside the engine, lubricating precision components like pistons and connecting rods while also helping to dissipate heat and clean carbon deposits, so it has better fluidity and contains various additives. Last time, my cousin tried to save time by pouring engine oil into the transmission, and shifting gears became as stiff as arm wrestling—costing him nearly two grand in repairs. A painful lesson indeed!
