Understanding the 2017 Toyota Highlander oil capacity is essential for maintaining the longevity and performance of this popular mid-size SUV. The correct oil volume ensures proper lubrication of the engine's moving parts, minimizes wear, and helps regulate operating temperature. Owners looking to perform their own oil changes or simply verify a mechanic's work must know the specific requirements for their model year.
Engine Specifications and Oil Requirements
The 2017 model year offered two primary engine choices, which dictated the oil capacity for the Highlander. These were a 3.5-liter V6 and a more powerful 3.5-liter V6 with direct injection, both part of Toyota's reliable Dynamic Force family. While the displacement remained similar, the specific design differences meant a precise answer to the 2017 Toyota Highlander oil capacity required looking at the engine code.
Capacity for the 3.5L V6 Engine
For the standard 3.5-liter V6 engine found in most trims, the total oil capacity is approximately 6.4 quarts. This figure includes the oil filter and the engine sump. When performing an oil change, it is recommended to add the majority of the oil, around 6 quarts, and then top off after replacing the filter to ensure you meet the exact level without overfilling.
Capacity for the 3.5L V6 Direct Injection Engine
Higher trims equipped with the more advanced direct injection engine also utilize a 3.5-liter configuration but often require a slightly different approach. The oil capacity for this variant remains very close, typically falling in the range of 6.4 to 6.6 quarts. Always refer to the dipstick reading after filling, as this is the most accurate method to confirm the 2017 Toyota Highlander oil capacity for your specific vehicle.
Type and Grade of Motor Oil
Knowing the capacity is only half the battle; selecting the correct type of oil is equally important for the 2017 Highlander. Toyota strongly recommends using a synthetic blend or full synthetic motor oil to ensure optimal performance and protection. The ideal viscosity grade is 0W-20, which provides excellent fuel efficiency and cold-start protection while maintaining sufficient lubrication at high temperatures.
0W-20 synthetic oil is the preferred viscosity for all weather conditions.
Ensure the oil meets the ILSAC GF-5 or API SN Plus certification standards.
Using conventional mineral oil is not recommended for this model year.
Always check the owner’s manual for the specific API service designation.
Step-by-Step Oil Change Procedure
When tackling the oil change on a 2017 Highlander, following the correct procedure ensures you achieve the proper level. First, warm up the engine for a few minutes to allow the old oil to drain more completely. Lift the vehicle securely on jack stands and remove the drain plug, allowing the oil to drain into a pan. Once drained, replace the drain plug and install a new oil filter, applying a small amount of new oil to the gasket.
After installing the new filter, pour approximately 5.5 quarts of the recommended 0W-20 synthetic oil into the engine. Start the engine and let it run for about 30 seconds, then turn it off. Wait a few minutes for the oil to settle, and check the dipstick. Add the remaining oil slowly until the dipstick reads between the "Full" and "Hot" marks, being careful not to exceed this level.
