Toyota 4Runner Oil Capacity by Engine & Year (2026 Reference Guide)

You pull the dipstick on your 4Runner after a long weekend in the dirt. Skid plates caked, rockers smeared, and you're standing at the parts counter with an empty quart in your hand. The jug says five. The guy behind the register said six. Your owner's manual is buried somewhere under the rear cargo mat. I've watched plenty of guys guess wrong and either short the engine or overfill it by half a quart. This guide gives you the exact fill for every 4Runner engine from 2003 through 2026, so you nail it the first time.

Quick Answer

Most 4Runners run a 4.0L V6 (2003-2024) that holds 5.5 quarts with a filter change. The 4.7L V8 (2003-2009) holds 6.6 quarts. The new 2025-2026 2.4L turbocharged four-cylinder holds 4.8 quarts. All three engines call for 0W-20 or 5W-30 depending on year. Always swap the drain plug crush washer and run the engine briefly to check for leaks before calling the job done.

4Runner Oil Capacity at a Glance: Full Year Chart

Here's the part most pages skip: a single chart covering every engine the 4Runner has worn since the third generation. The 4.0L V6 (engine code 1GR-FE) is the workhorse, riding under the hood from 2003 through 2024. The 4.7L V8 (2UZ-FE) only lived from 2003 to 2009 in SR5 and Limited trims. The brand-new 6th-generation 4Runner brings in a 2.4L turbo four with a hybrid option on top.

Year	Engine	Capacity (w/ filter)	Viscosity
2003-2009	4.0L V6 (1GR-FE)	5.5 qts	5W-30
2003-2009	4.7L V8 (2UZ-FE)	6.6 qts	5W-30
2010-2024	4.0L V6 (1GR-FE)	5.5 qts	0W-20
2025-2026	2.4L Turbo I4 (T24A-FTS)	4.8 qts	0W-20
2025-2026	2.4L Turbo Hybrid (i-FORCE MAX)	4.8 qts	0W-20

Use this chart to match your engine code, not just your model year. A 2009 SR5 with the V8 takes a full quart more than a 2009 SR5 with the V6. Get that wrong and you're either a quart light heading down I-70 or a quart heavy with foam building on the crank.

All numbers assume you swap the filter. If you're just draining and refilling without changing the filter, subtract about half a quart from each figure.

4.0L V6 Oil Spec: Third, Fourth, and Fifth Generation 4Runners (2003-2024)

The 1GR-FE is one of the easier engines to service in the Toyota lineup. The drain plug sits on the passenger side of the pan. The filter housing is right there in plain sight. The fill cap is huge.

Capacity is 5.5 quarts with a filter swap. Don't dump the whole 6-quart jug in. Pour five, let it settle, then top off the last half quart while reading the dipstick.

Drain plug torque is 27 ft-lb. Snug, not gorilla-tight. The pan is aluminum and the threads will tell on you if you crank down on it. Always use a fresh crush washer. They cost about thirty cents and save you a slow weep that turns into a driveway stain by spring.

Oil type and viscosity for the 4.0L

Toyota called for 5W-30 from 2003 through 2009. Starting in 2010, they shifted to 0W-20 full synthetic. Same engine, different recommendation. The change was driven by CAFE standards and tighter clearances in later production runs.

When to use 5W-30 vs 0W-20

If you live in Phoenix and tow a small camper to Sedona every other weekend, 5W-30 is a defensible choice even on a 2015. Hot ambient temps plus load equals a thicker film at operating temperature. Most owners I know running tall 33s and heavy bumpers go this route. If you're stock and you live anywhere it actually freezes, stick with 0W-20. It's what the door jamb sticker says for a reason.

For the filter, Toyota factory-style part 04152-YZZA1 is the standard cartridge. Mobil 1, WIX, and FRAM all build equivalents. Avoid the cheapest white-box filters at the truck stop.

4.7L V8 Oil Spec: 4Runner SR5 and Limited (2003-2009)

The 4.7L V8 4Runner is a unicorn. Toyota only sold it from 2003 to 2009, and most pages on the internet act like it never existed. If you're running one, you already know it's the smoothest 4Runner ever built and it'll go 300,000 miles without flinching.

Capacity is 6.6 quarts with the filter. Most references say 6.5 and you'll be fine either way. Pour six, let it settle, top off to the upper hash on the stick.

Toyota spec is 5W-30 for the 2UZ-FE, conventional or synthetic. Full synthetic isn't required, but if you're stretching to 7,500-mile changes, it's the right call. Most owners I know run Mobil 1 5W-30 and don't think twice.

Here's the trap: guys who trade up from a 4.0L V6 4Runner to a 4.7L V8 4Runner often pour 5.5 quarts out of habit and call it done. That's a full quart short. Check the dipstick. Always check the dipstick.

2.4L Turbo Four-Cylinder Oil Spec: 2025-2026 4Runner

The 6th-generation 4Runner ditched the V6 for a 2.4L turbocharged four (T24A-FTS), with an i-FORCE MAX hybrid version on the upper trims. Smaller displacement, more boost, more power. Same engine family as the new Tacoma.

Capacity is 4.8 quarts with a filter change. Both the gas-only and hybrid versions hold the same amount. The hybrid system runs off a separate battery and motor. The oil-lubricated engine itself is the same block.

Toyota requires 0W-20 full synthetic. Not recommended. Required. Turbocharged engines run their bearings and turbo seals at much higher temperatures than a naturally aspirated V6. The thinner cold-flow viscosity does real work in those first thirty seconds after a cold start. Use the wrong stuff and you'll wear out a turbo shaft long before the warranty runs out.

If you tow with the hybrid or wheel it in the desert, cut your oil change interval to 5,000 miles instead of the 10,000-mile factory recommendation. Confirm your exact engine code against the underhood sticker. Toyota updates these specs through dealer service bulletins, so the Toyota spec page is the source of truth before you write a check at the parts counter.

Oil Type by Year: What the 4Runner Actually Calls For

Anything 2010 or newer wants full synthetic. 2003-2009 V6 and V8 trucks can run conventional 5W-30 and live a long life. Most owners on those older trucks have switched to synthetic anyway because the price spread has shrunk and the longer drain intervals make sense.

Conventional vs full synthetic

For a 2008 V6 driven to work and the grocery store, conventional 5W-30 changed every 5,000 miles is perfectly adequate. For the same truck dragging a boat up Wolf Creek Pass in August, synthetic earns its keep. The film strength under heat is just better.

For 2010 and newer trucks, the question is moot. Toyota voids warranty arguments when you run conventional in a 0W-20 spec engine. Don't fight it.

Toyota Genuine Motor Oil vs third-party brands

Toyota's own 0W-20 is rebadged Mobil 1 in most regions. You're paying a Toyota markup for the same oil. Mobil 1, Pennzoil Platinum, Castrol Edge, and Valvoline SynPower all meet the ILSAC GF-6 spec the 4Runner needs. Pick one and stick with it.

While you're verifying your spec, it's worth confirming your trim too. The 3rd gen 4runner interior colors guide walks you through finding the trim code on your door jamb sticker, which is the same sticker that lists your oil spec.

Toyota's stated change interval is 10,000 miles on full synthetic and 5,000 miles on conventional. I run mine at 7,500 regardless. Cheap insurance.

How to Check and Add Oil on a 4Runner: Step-by-Step

Park on level ground. Not a slight slope, not the driveway lip. Level. A half-degree of tilt is worth a quarter-quart of misreading on the stick.

Shut the engine off and wait five minutes. The oil needs time to drain back into the pan. Check it hot off the highway and you'll think you're a quart low when you're fine.

The dipstick on the 4.0L V6 sits on the passenger side of the engine bay, yellow loop, hard to miss. Pull it, wipe it clean with a lint-free rag, reinsert it fully, then pull it again. Read it on the second pull. That first reading is splatter from the tube.

You're looking for oil between the two hash marks. The distance between MIN and MAX represents about one quart. If you're right at the bottom hash, you need a quart. Halfway between, half a quart. At or just under the top hash, you're done.

Add oil in half-quart increments. Pour, wait two minutes, check again. Overfilling is way easier than people think because the fill funnel makes it look like nothing's going in until suddenly it is. Once you're above the top hash by a quarter inch, you're risking crankcase foaming and seal damage.

After your change, start the truck, let it idle for thirty seconds, shut it down, and check for leaks under the drain plug and filter housing. Then re-check the level. Synthetic settles a little, and that final top-off matters.

Keeping the Interior as Clean as the Engine Bay

By the time you're done with an oil change, your hands are black, your jeans have a streak down the thigh, and you climbed back into the driver's seat to back the truck off the ramps without thinking twice. Now there's a smudge on the bolster.

4Runners are working trucks. Trail dust, dog hair, gear bags, kid seats, fishing tackle, and the occasional greasy palm print add up fast. The cloth on a TRD Off-Road shows it in under a year. The SofTex on a Limited holds up better but still cracks at the wear points by 80,000 miles.

This is where custom-fit covers earn their keep.

Frequently Asked Questions

Q: What kind of oil does a 4Runner 4.0 take?

The 4.0L V6 (1GR-FE) calls for 0W-20 full synthetic in 2010 and newer 4Runners. Models from 2003 through 2009 spec 5W-30 and can run conventional or synthetic. Capacity is 5.5 quarts with a filter change either way. The oil cap on top of the valve cover usually shows the viscosity in raised lettering. The door jamb sticker confirms it. When in doubt, that sticker is the source of truth.

Q: How much oil does a 4.7L V8 4Runner take?

The 4.7L V8 (2UZ-FE) holds 6.6 quarts with a filter change. This engine ran in the 4Runner from 2003 through 2009 only, in SR5 and Limited trims. Toyota specs 5W-30 conventional or synthetic. The most common mistake: dumping in 5.5 quarts out of habit from a V6 4Runner. Always check the dipstick after the first pour and add the final half quart in small increments.

Q: How much oil does a 2025 or 2026 4Runner take?

The 2025-2026 4Runner runs a 2.4L turbocharged four-cylinder (T24A-FTS) that holds 4.8 quarts with the filter. The hybrid i-FORCE MAX version holds the same amount because the engine block is identical. The hybrid system adds a motor and battery, not more oil. Toyota requires 0W-20 full synthetic. Don't substitute conventional in a turbo engine, ever.

Q: What happens if you overfill a 4Runner with oil?

Overfilling by more than half a quart lets the crankshaft whip the oil into foam. Foamed oil can't lubricate properly. Pressure drops at the bearings, and seals get pushed past their working range. You'll see smoke from the exhaust, smell oil burning off the manifold, and risk damaging the PCV system. If you overfilled, pull the drain plug and let a little out before you start the engine. Half-quart increments exist for a reason.

Q: How do I reset the oil life monitor on a 4Runner after an oil change?

Turn the ignition to On without starting the engine. Toggle the trip meter to ODO display. Turn the ignition off. Now hold the trip reset button down while turning the ignition back to On. Keep holding until the maintenance light flashes, then turns solid, then goes out. The procedure varies slightly between the 4th, 5th, and 6th generation trucks, so check the owner's manual for your year if the first attempt doesn't take.

Q: Does a 4Runner need full synthetic oil?

For 2010 and newer 4Runners, yes. Toyota's 0W-20 spec is a full synthetic spec, and running conventional in those engines voids the powertrain warranty for any oil-related claim. The 2025-2026 turbo four absolutely requires it. Older 2003-2009 V6 and V8 trucks can run conventional 5W-30 just fine, but synthetic gets you longer drain intervals and better cold-start protection. The price difference is small enough that most owners just run synthetic across the board.

When you're done with the oil change and the truck's back together, take a look at what the trail did to the cabin while you were under the hood. See the 2026 4runner seat covers. Same attention to factory spec we just applied to your dipstick, applied to your bucket seats.
