What kind of oil does Toyota use?

[MaliaDella]

Toyota vehicles use 0W20 or 5W20 engine oil. It is best not to use oil with a viscosity exceeding 5W30. Toyota vehicles are generally equipped with naturally aspirated engines, so standard oil will suffice. The functions of engine oil are as follows: 1. Reducing friction and high temperatures: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing effect: Engine oil can form a seal between the piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. 3. Anti-rust effect: Lubricating oil adheres to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning effect: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the pistons, piston skirts, connecting rods, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning effect: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away dirt generated on the working surfaces of parts through the flow of the lubricating oil.
