The 2004 Toyota Highlander's base engine, a 2.4-liter inline-4, requires 4 quarts of 5W30 synthetic oil, while the larger 3.3-liter V6 engine in the same model needs 5 quarts of the same oil type. Synthetic oil is superior for performance as it reduces friction and provides better engine protection. It is safe to switch between synthetic and conventional oils without harming the engine. Synthetic blends combine synthetic and conventional oils. It is recommended to change your oil every 7,500 miles or annually, whichever comes first, to help eliminate engine particles and sludge. Failure to change the oil can lead to significant engine issues in your vehicle.
What kind of oil should I use? Is 5W30 okay?
The 2004 Toyota Highlander has a 2.4-liter inline-4 standard engine that requires 4 quarts of 5W30 synthetic oil, and if you opt for the 3.3-liter V6 engine, it will need 5 quarts of the same 5W30 synthetic oil.
