The preferred oil for the 2010 Toyota Highlander is any brand with an API certification seal and a viscosity rating of either 5W-20 or 0W-20 sae. The SUV's engine requires 6.4 quarts (6.1 liters) for the 3.5L v6 engine, as per the manufacturer's specifications. It is recommended to change the oil every 3500 to 5000 miles or every 6 months on average. You have the option to use either conventional or synthetic oil in the vehicle, but it's important not to mix them. While conventional oil is more affordable than full synthetic, you may need to service the vehicle more frequently with conventional oil as it doesn't maintain its viscosity as well, leading to decreased lubrication effectiveness for the engine components.
