What Toyota Highlander oil types should you use? For new Toyota Highlander models, you will want to use the Toyota Genuine full synthetic 0w-20. For older Highlander models, you will want to check out the Toyota Genuine full synthetic 5w-30. Both types of oil are great in higher and lower temperatures, and you can enjoy great performances all around Sulphur Springs, TX and Greenville, TX.
