The Highlander uses 0W-20 synthetic engine oil for both the 2.7L four-cylinder and the 3.5L V6 engines.
In 2016, Toyota offered two gasoline engines for the Highlander, but the recommended oil grade is the same across configurations. The following details cover the grade, capacity, and service considerations you should know when maintaining the engine oil.
Oil specifications and capacity
The list below summarizes the essential oil details for the 2016 Highlander.
- Oil type and viscosity: 0W-20 synthetic engine oil.
- Engine compatibility: both the 2.7L four-cylinder and the 3.5L V6 require 0W-20.
- Oil grade and standards: oil should meet API SP (or newer) and ILSAC GF-5 (or newer).
- Oil capacity (approximate): about 4.7 quarts (with filter) for the 4-cylinder; about 6.0 quarts (with filter) for the V6.
- Oil change interval: with synthetic 0W-20, many owners follow a 10,000-mile (or 12-month) schedule, though severe driving conditions may require more frequent changes.

When in doubt, consult the owner's manual or a Toyota dealer for the exact figures for your vehicle's VIN and engine configuration.

Keeping the oil within recommended specs helps maintain engine protection, fuel efficiency, and resale value. Always check for leaks, monitor oil level regularly, and replace the oil filter with every change.
