How Many Liters of Oil Should a 1.5L Engine Take?
2 Answers
1.5L engines typically require 3.5 to 4.5 liters of oil. Below is an introduction to engine oil: Functions of Engine Oil: Separate the relative sliding surfaces between pistons and cylinders, main shafts and bearing bushes to reduce wear on components; carry heat back to the oil tank and dissipate it into the air, assisting the radiator in cooling the engine; form a seal between piston rings and pistons to reduce gas leakage and prevent external contaminants from entering; circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, cleaning the working surfaces of components; adhere to part surfaces to prevent contact with water, air, acidic substances, and harmful gases; and cushion impact loads on pistons, piston chips, connecting rods, and crankshaft bearings. Effects of Excessive Oil: Excessive oil causes intense agitation among engine components during operation, increasing internal power loss and leading to more oil splashing onto cylinder walls, which can result in oil burning issues. Effects of Insufficient Oil: Insufficient oil leads to poor lubrication between bearings and journals, exacerbating wear and potentially causing bearing seizure accidents.
I drive a 1.5L displacement car. Last time I changed the oil, I specifically asked the technician, and he said about 4.2 to 4.5 liters would do, but it depends on the specific model. For example, my compact sedan took exactly 4.3 liters. Don't rely on guesswork when adding oil—measure accurately: too little oil leads to insufficient lubrication, rapid engine wear, and overheating warnings; too much oil increases crankshaft resistance, spikes fuel consumption, and can cause leaks. Every time I change the oil myself, I warm up the engine, turn it off, wait ten minutes, then use the dipstick to check between the min-max lines—top up if low, drain if overfilled. I recommend checking the user manual or online model forums. Japanese cars might need around 4 liters, while European turbocharged versions might require slightly more, up to 5 liters. Change the oil regularly every 5,000 km to maintain performance. Don’t cut corners and get it wrong—repairs are expensive if the car breaks down.
