Toyota Highlander Oil Capacity & Oil Type
TL;DR
Highlander oil capacity varies by engine code, roughly 4.6 to 6.4 US qt with filter. Always confirm against your underhood emissions/oil sticker or owner's manual before filling.
Why there is no single number
The Toyota Highlander has been built across five generations since 2001, with several unrelated engine families along the way (1MZ-FE V6, 1AR-FE 4-cylinder, 2GR-FE V6, 2GR-FKS V6, A25A-FXS hybrid 4-cylinder, and the newest T24A-FTS 2.4L turbo). Oil capacity with a filter change is tied to the engine code, not the model year or trim name alone, so a figure for one generation should never be assumed to apply to another.
Verified capacities by engine
The table below lists only the figures confirmed against oil-lookup databases and lubricant manufacturer fitment tools for each specific engine code. Where sources showed minor rounding differences, the most commonly cited figure is used.
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 1MZ-FE 3.0L V6 (2001-2003) | 4.7 L / 5.0 qt | 5W-30 (10W-30 acceptable) |
| 1AR-FE 2.7L I4 (2014-2019) | 4.35 L / 4.6 qt | 0W-20 |
| 2GR-FE 3.5L V6 (2014-2019) | 6.06 L / 6.4 qt | 0W-20 |
| 2GR-FKS 3.5L V6 (2020-2024) | 5.5 L / 5.8 qt | 0W-20 |
| A25A-FXS 2.5L Hybrid (2020-2024) | 4.5 L / 4.8 qt | 0W-16 |
| T24A-FTS 2.4L Turbo, gas and hybrid (2025-present) | 5.3 L / 5.6 qt (commonly cited figure) | 0W-20 |
Where to get the exact number for your specific vehicle
- The engine oil viscosity and capacity are printed on the oil filler cap or on a sticker under the hood, near the engine.
- The owner's manual maintenance section lists exact fill quantities for your specific engine and includes any hybrid-system adjustments.
- The driver's door jamb placard confirms tire pressure and some fluid notes, though full oil-fill data is usually in the manual, not on that placard.
- A dealer parts or service department can pull the exact figure from Toyota's service data system using your VIN.
2001-2013 and older 2.7L/3.3L variants
Early first- and second-generation Highlanders also used a 3.3L V6 (3MZ-FE) and a 2.4L I4 (2AZ-FE) in some markets and years. Reliable, sourced capacity figures for those specific engine codes were not found during this review, so no number is stated here for them - check your filler cap or manual if you own one of these earlier configurations.

Frequently asked questions
Does the Highlander Hybrid really need a different oil than the gas V6?
Yes. The 2020-2024 Highlander Hybrid (A25A-FXS engine) is designed around 0W-16, a thinner grade than the 0W-20 used in the gas V6 engines, to reduce friction and improve fuel economy. Using 0W-20 in place of 0W-16 is not recommended long-term; check your filler cap or manual to confirm which grade your specific hybrid model calls for.
Why do some online sources give different quart figures for the same Highlander engine?
Minor rounding differences appear because oil databases sometimes round the manufacturer's liter figure differently, or include a small dipstick tolerance range. The differences are usually a few tenths of a quart. If two credible sources disagree, treat it as a range and always confirm the exact figure against your own vehicle's filler cap or owner's manual before adding oil.
Is oil capacity the same across all trims of one engine, like LE versus Platinum?
Yes, oil capacity is determined by the engine itself, not the trim level. An LE and a Platinum Highlander with the same engine code (for example, both with the 2GR-FKS V6) take the same amount of oil. Trim only affects features, not the powertrain's fluid specifications, unless the trim also changes the engine or drivetrain option.
What happens if I put in slightly too much or too little oil?
Overfilling can cause foaming and pressure issues that reduce lubrication effectiveness, while underfilling can starve the engine of oil under load. Always fill close to the specification, then check the dipstick after a few minutes with the engine off and the vehicle on level ground, adding or draining small amounts to reach the correct mark.
