Getting the 2016 toyota highlander 3.5 oil capacity wrong is an easy mistake. You dump in an extra quart because it feels like it should hold more. Or you stop short because the jug looks empty.
But the 2GR-FKS V6 is picky about its oil volume. Too much or too little leads to real damage. Toyota specifies exactly 5.7 quarts of 0W-20 full synthetic with a filter change.
That number comes straight from the factory manual. Let's walk through why it matters and how to get it right every time.

Why Getting This Number Wrong Can Cost You Thousands
Overfilling the 2GR-FKS causes oil foaming. The crankshaft whips air into the oil, reducing its lubricating ability. Foamy oil doesn't protect bearings or the variable valve timing system.
Seal leaks often follow.
Underfilling is worse. Starve the oil pump at highway speed and bearing damage happens fast. A spun rod bearing means a new engine or a complete rebuild.
That's a $5,000 to $8,000 repair.
Wrong viscosity creates its own problems. Thicker oil struggles to reach the VVT actuators at cold start. Thinner oil breaks down under high heat.
Both reduce engine life.
The 2GR-FKS uses dual injection (port and direct). This system is sensitive to oil quality. Sludge from wrong oil can clog the timing chain tensioner.
Replacements cost over $1,500.
Across multiple Toyota service records, incorrect oil volume is one of the most common DIY mistakes on this platform. The fix is simple: measure twice, pour once.
Quick Answer: 2016 Highlander 3.5 Oil Capacity (The Short Version)
The 2016 Highlander 3.5 takes 5.7 quarts of 0W-20 synthetic oil. That's with a filter change. Without a new filter, you need 5.2 quarts.
Use only API SN or higher certified oil. As of 2026, this spec remains unchanged.
The 2GR-FKS Engine: What You're Working With
The 2GR-FKS is a 3.5-liter V6 that Toyota introduced in 2015. It replaced the older 2GR-FE and brought significant improvements. Dual injection gives it cleaner valves and better fuel economy.
It produces 295 horsepower in the Highlander.
This engine uses a timing chain, not a belt. That's good for longevity. But the chain tensioner relies on clean, consistent oil pressure.
Skipping oil changes or using the wrong oil can starve the tensioner. The result is a rattling chain and expensive repairs.
The 2GR-FKS also appears in the Tacoma, Sienna, and Lexus RX 350. Each application has slightly different oil capacity. The Highlander's sump holds 5.7 quarts with a filter.
The Tacoma's version shares the same pan, but some other Toyota models use a different sump design with a different fill volume.
Compared to other Toyota engines, the 2GR-FKS is more oil-sensitive. The older 2GR-FE could tolerate 5W-30 in a pinch. The 2GR-FKS needs 0W-20 to operate correctly.
The VVT-iW system requires thin oil for fast actuation at cold start.
Exact Oil Specifications for the 2016 Highlander 3.5L

Let's get the numbers straight. Here's the full spec sheet:
| Specification | Value |
|---|---|
| Capacity with filter | 5.7 US quarts (5.4 liters) |
| Capacity without filter | 5.2 US quarts (4.9 liters) |
| Oil viscosity | SAE 0W-20 |
| Oil type | Full synthetic only |
| API certification | SN or higher (SP recommended) |
| ILSAC standard | GF-5 or GF-6 |
| Drain plug torque | 27 lb-ft (37 Nm) |
| Filter housing torque | 18 lb-ft (25 Nm) |
Capacity With Filter vs. Without Filter
The difference between 5.7 and 5.2 quarts is the filter volume. The 2GR-FKS uses a cartridge-style filter. It holds about half a quart of oil when dry.
Always replace the filter with every oil change. The cost is minimal and the benefit is significant.
Oil Type and Viscosity
Only 0W-20 full synthetic oil belongs in this engine. Do not substitute 5W-20 or 5W-30. The 0W rating ensures easy cold starts.
The 20 hot-rating provides proper viscosity at operating temperature.
Toyota Genuine 0W-20 is the factory fill. It's a good oil. But any brand that meets API SN or SP will work.
Mobil 1, Pennzoil, Castrol, and Valvoline all make compatible 0W-20 synthetics. We've covered the oil type in more detail in our full Highlander oil guide.
API and ILSAC Certifications
Look for the API donut on the bottle. It should say SN or SP. SP is the newer standard and offers better protection against low-speed pre-ignition.
The ILSAC GF-6 certification covers the same ground.
Using oil without these certifications voids your warranty. It also increases the risk of sludge buildup. The American Petroleum Institute maintains a list of certified oils.
Check it if you're unsure about a brand.
Step-by-Step Oil Change Process

Changing the oil on a 2016 Highlander is straightforward. You can do it in your driveway in about 45 minutes. Here's the full process.
What You'll Need
| Item | Details |
|---|---|
| 0W-20 synthetic oil | 6 quarts (5.7 for fill, 0.3 for top-off) |
| Oil filter | OEM 04152-YZZA1 or equivalent |
| Drain plug crush washer | OEM 90430-12031 or equivalent |
| 17mm socket or wrench | For the drain plug |
| 64mm or 65mm oil filter cap wrench | For the cartridge housing |
| Torque wrench | 1/2-inch drive, 10-50 lb-ft range |
| Oil catch pan | 8-quart capacity minimum |
| Funnel | Long neck for the fill port |
| Ramps or jack stands | Safe access to the underside |
Draining the Old Oil
Warm the engine first. A short 5-minute drive warms the oil enough to flow freely. Hot oil drains faster and carries more suspended contaminants.
Park on level ground. Use ramps for the best access. Never work under a vehicle supported only by a scissor jack.
Locate the drain plug on the passenger side of the oil pan. It's a 17mm bolt. Place your catch pan underneath.
Loosen the bolt with a socket, then remove it by hand. Let the oil drain for at least 5 minutes.
Replace the crush washer. This is a one-time-use part. A used washer can leak.
Torque the drain plug to 27 lb-ft. Over-tightening strips the aluminum pan threads.
Removing and Replacing the Filter

The 2GR-FKS uses a cartridge filter. It sits on the front of the engine, driver's side, behind the alternator. You'll need a 64mm or 65mm cap wrench to remove the housing.
Place the catch pan under the filter housing. Loosen the cap slowly. Some oil will drain from the housing.
Remove the cap completely and pull out the old cartridge.
Compare the new filter to the old one. They should match exactly. Lubricate the new filter's O-ring with fresh oil.
Install the new cartridge and hand-tighten the cap. Torque to 18 lb-ft. Many people over-tighten this and crack the housing.
Filling to the Right Level
Remove the oil fill cap on top of the valve cover. Insert a funnel. Pour in 5.7 quarts of 0W-20 synthetic oil.
Replace the cap tightly.
Start the engine and let it idle for 30 seconds. This primes the new filter. The oil pressure light should go out within a few seconds.
If it stays on, stop the engine and check for leaks.
Turn off the engine. Wait 2 minutes for the oil to settle. Pull the dipstick, wipe it clean, reinsert it, and check the level.
The oil should be between the Low and Full marks. Top off if needed.
Resetting the Maintenance Light
The 2016 Highlander has a maintenance reminder light. It comes on based on mileage, not oil condition. After your oil change, reset it manually.
Turn the ignition to ON (not started). Press the odometer trip button until the trip meter shows. Turn the ignition OFF.
Press and hold the trip button. Turn the ignition to ON while holding the button. Wait for the maintenance light to flash and then turn off.
Release the button. The light is now reset.
Common Mistakes That Damage This Engine
Mistakes here cost real money. Let's run through the biggest ones.
| Mistake | Why It Hurts | What It Costs |
|---|---|---|
| Overfilling an extra quart | Oil foams, seals leak | $500+ for valve cover reseal |
| Using 5W-30 instead of 0W-20 | Slow cold-start lubrication | Premature chain tensioner wear |
| Stripping the drain plug threads | Oil pan replacement | $400 to $700 |
| Skipping the crush washer | Chronic oil drip | $10 part, $100 labor |
| Reusing the filter O-ring | Housing leak, low oil pressure | $50 filter replacement |
Overfilling happens more than you'd think. A 4-quart jug and a 2-quart jug can be confusing. Pour 5.7 and stop.
The dipstick is your final check.
Underfilling is just as common. Some owners trust the math and skip the dipstick check. That's how you find out at 70 mph why the oil pressure light means business.
If you're unsure whether your oil meets the spec, the right blend for this engine is covered inside our Highlander oil guide. Take five minutes to read it before you refill.
Cost Breakdown: DIY vs. Shop
An oil change on the 2016 Highlander is cheap to DIY. A 6-quart jug of quality 0W-20 runs $25 to $40. A genuine Toyota filter costs about $12.
The crush washer is under $3.
| Option | Parts | Labor | Total |
|---|---|---|---|
| DIY | $40 to $55 | $0 | $40 to $55 |
| Quick-lube shop | $50 to $70 | $0 | $50 to $70 |
| Toyota dealership | $75 to $95 | $75 to $95 flat | $75 to $95 |
The dealership figure includes an inspection and the proper filter. Quick-lube shops sometimes use spec-compliant aftermarket filters. Those are fine as long as they meet API standards.
If you plan on keeping the Highlander past 150,000 miles, DIY is the reliable route. You control the quality of every part. And you'll spot small leaks early since you're under the car anyway.
When to Use the "Severe Service" Interval
Toyota lists two maintenance schedules for the 2GR-FKS. The normal interval is 10,000 miles. The severe service interval is 5,000 miles.
Which one applies to you? It depends on how and where you drive.
- Frequent short trips under 5 miles
- Extended idling (delivery work, drive-thrus)
- Dusty or sandy roads
- Towing a trailer or roof cargo
- Sub-zero or triple-digit temperatures
If three or more of these describe your routine, lean toward 5,000 miles. Owner forums report cleaner valve trains and fewer timing-chain issues at 5,000. The used-oil analysis community supports that.
Toyota applies the same severe-service split across its V6 lineup. The V6 Tacoma follows the same maintenance pattern. The Sienna's V6 also follows the same severe-service guidance.
Pro Tips for High-Mileage Highlanders
Once the odometer passes 100,000 miles, the 2GR-FKS deserves a bit more attention. Here's what aggregate driver feedback and service records suggest.
- Switch to a high-mileage 0W-20. It has seal conditioners that help reduce minor seepage.
- Keep the filter genuine. Aftermarket filters sometimes don't match the bypass valve pressure. The OEM filter is only $12.
- Check the level at every other refueling stop for the first week after an oil change. Some Highlanders consume a quarter quart per 5,000 miles. Others don't burn a drop.
- Keep a note in your phone with date, mileage, oil brand, and filter part number. Three years from now, you'll thank yourself.
- Avoid additives. A quality 0W-20 already has the detergents your engine needs. Extra treatments can disrupt the formulation.
If you're also working on other Toyota SUVs, the 4Runner's V6 has its own requirements. And if you're juggling multiple Toyotas, the Camry's requirements differ from the Highlander, but the habit is the same. Cross-check the spec before you pour from the wrong jug.
Safety and Disposal Warnings
Used oil is hazardous waste. It can poison soil and groundwater. It's regulated in every state, and federal rules from the Environmental Protection Agency treat it as dangerous material.
Never dump it down a drain, onto the ground, or into a storm sewer.
Most auto parts stores accept used motor oil for free. Call ahead, then pour it into a sealed container with a tight lid. Some locations also take your old filter for recycling.
When working under the Highlander, use ramps or jack stands. A scissor jack can slip, and a two-ton SUV is not something you want to be beneath. Position jack stands on the frame rails, not the floor pan.
Hot oil causes burns. Let the engine cool for 10 to 15 minutes before draining. Wear nitrile gloves and safety glasses.
And keep a shop towel nearby because the filter housing always bleeds oil.
Proper disposal and basic precautions take an extra 10 minutes. Skipping them can cost a lot more.
FAQs
Here are the questions that come up most often in owner forums and service bays.
How many quarts of oil does a 2016 Toyota Highlander 3.5 take?
5.7 quarts with a new filter. That works out to 5.4 liters. Without a filter, it takes 5.2 quarts.
Always install a fresh filter so the full capacity applies. If you also own a RAV4, check the RAV4's oil requirements separately.
What type of oil does a 2016 Toyota Highlander need?
0W-20 full synthetic with API SN or SP certification. ILSAC GF-5 or GF-6 approval is the same standard. Toyota Genuine 0W-20 is the factory fill.
Other brands work as long as they carry the API donut. For a deeper breakdown, our Venza oil type guide covers the same 0W-20 spec.
Can I use 5W-30 in my 2016 Highlander?
No. The 2GR-FKS engine is designed around 0W-20. The VVT system needs that thin cold-start flow.
The Tacoma V6 shares this trait, so don't swap viscosities there either. Stick with what the manual says and the engine will reward you.
How often should I change the oil in my 2016 Highlander?
Every 10,000 miles on the normal schedule. Use the 5,000-mile severe service interval for towing, idling, or short trips. Cold climates and dusty roads also push you into severe territory.
The Sienna's maintenance schedule follows the same pattern if you're juggling multiple vehicles.
What happens if I overfill my Highlander?
The crankshaft whips air into the oil, which causes foaming. Seals leak and engine performance drops. Drain the excess down to the full mark right away.
Check the dipstick after a few minutes of settling. The same logic applies to the Camry's oil capacity.
