The 2014 Toyota Highlander requires 0W-20 motor oil and can hold up to 6.4 US quarts with the filter. If necessary, you can use 5W-20 as a substitute, but make sure to switch back to the recommended oil at the next oil change to prevent damage to your SUV. It's important to regularly change your oil, with Toyota suggesting intervals of every 7,500 to 10,000 miles for synthetic oil and every 3,000 to 5,000 miles for conventional oil. Monitoring your oil monthly for color (clear vs. dark brown) and ensuring the level is between the minimum and maximum lines will help maintain your vehicle's health and longevity.
For the 2014 Highlander, Toyota suggests using Toyota Genuine Motor Oil SAE 0W-20, which is a synthetic oil. If you can't find 0W-20, you can use SAE 5W-20 instead until your next oil change when 0W-20 becomes available.
