How many liters of engine oil does the 3.5L Highlander require?
2 Answers
If all the engine oil is drained, it requires 4 liters of oil for refill. Below are the specific details about engine oil: 1. As a lubricant for the engine, engine oil continuously flows into various transmission components during engine operation, forming an oil film between friction surfaces. This reduces friction resistance, lowers power consumption, and minimizes component wear. 2. During maintenance, the amount of engine oil to be added at once depends on the engine type. Small-displacement vehicles require 3.2~3.6 liters per maintenance, while larger-displacement engines need approximately 4.5 liters. Additional information: Precautions for using engine oil include selecting the appropriate oil based on 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.
When changing the oil for this 3.5L Highlander, I remember it usually requires about 6.5 liters. Last time I went for maintenance, that's the amount I added. In actual operation, it's best to check the vehicle's user manual first, as there might be slight variations for different model years—older models might need a bit more, while newer ones might require less. Don't overfill the oil, as excessive pressure can damage the engine, but also avoid underfilling, as insufficient lubrication can cause engine wear. I recommend using full synthetic oil, which is suitable for Japanese cars, offering durability and fuel efficiency. By the way, regular oil changes are quite important—typically every 5,000 to 10,000 kilometers—to ensure the car runs well for a long time. If you're changing the oil at home, remember to park the car on a level surface, drain the old oil first before adding new oil, and take your time—no need to rush.
