The 4.0-liter V6 engine used in many Toyota 4Runners typically requires about 6.6 quarts (6.3 liters) of engine oil for a full change with a new filter. If you do not replace the filter, you’ll need roughly 5.6–5.8 quarts. Always verify with the dipstick and your owner's manual for your exact year and configuration.
Engine and capacity basics
The 4.0L powerplant in most 4Runners is the Toyota 1GR-FE. This engine family has a consistent oil capacity figure across many model years, but minor differences can occur due to filter size, mounting, and year-specific engineering tweaks. Planning for a full change with a fresh filter helps ensure you reach the proper full-mark on the dipstick.
Before you consult the numbers below, it’s useful to know the standard capacities several DIYers rely on when performing an oil change.
- With a new oil filter: 6.6 quarts (6.3 liters).
- Without replacing the filter: about 5.6–5.8 quarts (5.3–5.5 liters).
These figures provide a practical reference for most 4.0L 4Runners, but exact capacity can vary by year and filter choice. Always confirm by checking the dipstick after filling and refer to the specific year’s manual.
Year-to-year nuances and practical guidance
Most 4Runners equipped with the 1GR-FE 4.0L share the same general capacity, yet Toyota’s official specification can show small year-to-year differences depending on the oil filter used and any factory changes. When in doubt, treat 6.6 quarts as the target for a standard oil-and-filter change and adjust if your measurement indicates a different level.
Oil type, viscosity, and maintenance tips
Along with knowing how much oil to buy, use the viscosity recommended by Toyota for your climate and model year. The 1GR-FE commonly calls for a synthetic 5W-30 in many markets, with occasional variations. After an oil change, run the engine, recheck the level, and top off to the full mark if needed. Reset any oil-change indicator if your vehicle is equipped with one.
Notes and caveats
Capacity can vary slightly by model year, regional specifications, or aftermarket filters. If you’re performing an oil change on a vehicle with modifications or unusual filters, rely on the dipstick and cross-check the owner’s manual for the exact figure for your exact VIN.
Summary
For most Toyota 4Runners with the 4.0L V6 (1GR-FE), plan on about 6.6 quarts (6.3 liters) of engine oil when you replace the filter during an oil change. If you skip replacing the filter, you’ll typically need around 5.6–5.8 quarts. Always verify with the dipstick after filling and consult the owner’s manual for year-specific guidance.
