Approximately 5 quarts (about 4.7 liters) of engine oil are needed for a full oil change on the 2007 Highlander with the 2.4-liter engine, including the oil filter. This is the standard figure offered by Toyota for this engine, though capacities can vary slightly by market or service procedure. Always verify with your owner's manual or dealer if you are unsure.
Oil capacity and specification
The Highlander 2.4L’s oil capacity is commonly listed with two related figures, depending on whether the oil filter is being replaced. The following figures reflect typical capacities for the 2007 model year with the 2.4L engine:
- Oil capacity with filter: 5.0 quarts (approximately 4.7 liters)
- Oil capacity without filter: roughly 4.5–4.7 quarts (approximately 4.3–4.5 liters)
In practice, plan for about 5 quarts when performing a full change with a new filter, and use the dipstick to confirm you are within the proper range after filling and running the engine.
Oil type and maintenance guidance
For the 2.4L engine, Toyota typically recommends a 5W-30 viscosity that meets API SN or ILSAC GF-5 standards. You can use conventional or full-synthetic oil; synthetic may allow longer intervals between changes depending on driving conditions. A typical maintenance interval is around 5,000 miles (8,000 kilometers) with conventional oil and up to 7,500–10,000 miles with synthetic oil, again depending on usage and climate.
Practical tips for changing the oil
Always start by warming the engine slightly, place the vehicle on a level surface, and use a clean filter and gasket. After draining and replacing the filter, fill to the lower mark on the dipstick, run the engine, then recheck the level and top up to the correct mark as needed.
Summary
The 2007 Toyota Highlander 2.4L engine takes about 5 quarts of oil with the filter installed for a full oil change, with around 4.5–4.7 quarts if the filter is not replaced. Use 5W-30 oil meeting API SN or ILSAC GF-5 standards, and follow your manual for the recommended change interval and any climate-specific guidance. Always verify the final oil level with the dipstick after refilling.
