Toyota 4Runner Oil Capacity & Oil Type
TL;DR
There is no single correct number for every 4Runner - capacity changed at least three times across generations, from roughly 5.5 to 6.6 quarts depending on engine and year. Confirm against the table below, then verify on your own vehicle before topping off.
Why one number does not fit every 4Runner
The 4Runner has been built with at least five distinct engines since 2003, and Toyota changed the oil pan and filter housing design more than once along the way. That means two 4Runners with the same nameplate can call for noticeably different amounts of oil. The safest approach is to identify your engine code (stamped on the engine block, or listed in your owner's manual specifications page) before buying oil or setting a fill target.
Capacity and viscosity by engine and generation
The figures below come from Toyota-aligned lookup tools (AMSOIL, engineoildb), oil-change specification databases and, where noted, an owner's manual quote shared by 4Runner owners. Where sources disagreed, a range is shown instead of one invented number.
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 2.7L I4, 2TR-FE (2003-2009) | approx. 5.2-5.8 L (5.5-6.1 qt) - sources vary | 5W-30 (confirm on your fill cap; later units may show 0W-20) |
| 4.0L V6, 1GR-FE (2003-2009) | 5.5 L (5.8 qt) - per owner's manual quote | 5W-30 |
| 4.7L V8, 2UZ-FE (2003-2009) | 6.2 L (6.55 qt) | 5W-30 |
| 2.7L I4, 2TR-FE (2010-2013, base SR5) | approx. 5.2-5.8 L (5.5-6.1 qt) - sources vary | 0W-20 |
| 4.0L V6, 1GR-FE (2010-2024) | 6.2 L (6.6 qt) | 0W-20 |
| 2.4L turbo I4, T24A-FTS, non-hybrid (2025-2026) | 5.6 L (5.9 qt) | 0W-20 |
| 2.4L turbo I4 hybrid, i-FORCE MAX, T24A-FTS (2025-2026) | 5.6 L (5.9 qt) - same block as the non-hybrid per owner-forum data | 0W-20 |
Where the truly correct number lives
Whatever generation you drive, the figure that overrides everything on this page is printed on your own vehicle: check the oil filler cap for the viscosity grade, the engine oil specifications page inside your owner's manual for the exact fill volume, and the dipstick after refilling to confirm level rather than trusting a poured amount alone. The driver's door jamb placard covers tire and loading data, not oil, but it is worth checking together with the manual during any service.
A note on the rows marked (sources vary)
For the 2.7L four-cylinder across both generations, published references range from about 5.5 to 6.1 quarts with filter. Rather than pick one figure and present it as certain, this page shows the range - pour to the lower figure, check the dipstick, and add in small increments if needed.

Frequently asked questions
Why do some websites list 6.6 quarts and others 5.8 quarts for the same V6?
Both can be correct depending on model year. The 4.0L V6 (1GR-FE) kept the same engine code from 2003 through 2024, but Toyota revised the oil pan and filter housing when the 4Runner moved to its fifth generation in 2010, which increased the fill volume from about 5.8 quarts (2003-2009) to about 6.6 quarts (2010-2024). Check which generation you have before trusting either number.
Does the i-FORCE MAX hybrid take the same oil as the standard turbo 4Runner?
Based on available data, yes - both the 2.4L turbo (T24A-FTS) and the i-FORCE MAX hybrid version share the same combustion engine block, and owner reports point to the same 5.9 quart (5.6 liter) fill with 0W-20 for both. The hybrid's electric motor and battery do not add to the engine oil circuit, so this is expected, but confirm against your build sheet since Toyota has not published a separate widely-cited spec sheet for the hybrid variant yet.
What viscosity should I use if I cannot find 0W-20 for an older 4Runner?
For 2003-2009 4Runners (2.7L, 4.0L V6, or 4.7L V8), Toyota specified 5W-30 as the standard year-round oil, so that is the correct grade to buy, not 0W-20. For 2010-and-newer V6 models and all 2025+ turbo and hybrid models, Toyota specifies 0W-20; if that is genuinely unavailable, 5W-20 can be used temporarily but should be replaced with 0W-20 at the next service.
My 4Runner takes noticeably less oil than the table shows - is that a problem?
Not necessarily. The quart figures above are the full refill amount with a new filter; a quick top-up without a filter change, or an engine that was not fully drained, will always take less. If the difference is large and consistent across multiple oil changes, have a mechanic check for a leak or confirm you have the engine code you think you have.
