How Many Liters of Engine Oil Does the Highlander Need?
2 Answers
Toyota Highlander typically requires approximately 4.5L of engine oil, with the exact amount determined by the oil dipstick markings. If too much oil is added to the Toyota Highlander, it increases the amount of oil splashed onto the cylinder walls by the rotating crankshaft and connecting rods, significantly raising the quantity of oil entering the combustion chamber. Method for measuring engine oil: Turn off the vehicle and park it on level ground; after the engine cools to normal temperature, open the hood, pull out the oil dipstick; wipe the dipstick clean, reinsert it, then pull it out again to check the oil level. Choosing engine oil based on the engine: Select engine oil according to the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher demands.
As a Highlander owner, my experience is that the engine requires about 4 liters of oil during each oil change, as recommended by the user manual. Over the years of driving, I've found that 4 liters is just right – any less and the engine noise increases with insufficient lubrication leading to wear; any more may cause overflow to other components, resulting in oil seepage. During the actual operation, I slowly pour the oil through the filler port and use the dipstick to check that the level is at the midpoint. I usually check the oil level once after the oil change cycle to ensure it's normal. Remember to use the appropriate viscosity, such as 0W-20, to adapt to seasonal changes. Once, I carelessly added an extra 0.5 liters, which resulted in slower acceleration, and I had to quickly drain the excess. In short, don't take risks – referring to the manual is the safest way, saving money and ensuring safety.
