Lexus GX Oil Type and Capacity: A Service Guide for the 2010–2027 GX 460 and GX 550
A 2010–2023 Lexus GX 460 with the 4.6-liter V8 takes 8.2 quarts (7.8 liters) of SAE 0W-20 full synthetic motor oil with a filter change. Without a filter change, it takes 7.8 quarts (7.4 liters). A dry fill after an overhaul takes 9.9 quarts (9.4 liters). The 2024–2027 GX 550 with the 3.4-liter twin-turbo V6 takes 7.7 quarts (7.3 liters) with a filter change.
Both generations use the same viscosity grade. Almost nothing else about their oil service matches. The engines differ, the capacities differ, and the two use completely different filter designs. This guide covers each generation separately, so you fill to the right level and order the right part the first time.

How Much Oil Does a 2010–2023 Lexus GX 460 Take?
GX 460 Oil Capacity
A standard oil change on a 2010 through 2023 Lexus GX 460 takes 8.2 quarts (7.8 liters) with a new filter element. Draining the pan without changing the filter takes 7.8 quarts (7.4 liters). A completely dry engine after an overhaul takes 9.9 quarts (9.4 liters).
The 4.6-liter V8 uses a cartridge-style filter housing. That housing holds roughly 0.4 quarts of oil inside the chamber and the element folds. It also retains spent oil and trapped debris, so skipping the filter leaves dirty fluid in the lubricating circuit. Replacing the cartridge at every interval is what keeps fresh oil clean.
GX 460 Drain Plug and Filter Housing Specifications
Proper procedure starts with a new OEM drain plug crush washer, part number 90430-12031. Torque the oil pan drain plug to 30 ft-lb. The cartridge filter cap tightens to 18 ft-lb with a dedicated filter housing tool. The cap seals on its O-ring rather than on clamping force. Overtightening the composite housing cap risks hairline cracks and leaks under pressure.
| GX 460 Service Specification | Value |
|---|---|
| Oil capacity — with filter change | 8.2 qt (7.8 L) |
| Oil capacity — without filter change | 7.8 qt (7.4 L) |
| Dry fill — after overhaul | 9.9 qt (9.4 L) |
| Filter housing volume | Approximately 0.4 qt |
| Oil pan drain plug torque | 30 ft-lb (40 N·m) |
| Filter housing cap torque | 18 ft-lb (25 N·m) |
| Drain plug gasket (OEM) | 90430-12031 |
| Oil filter element kit (OEM) | 04152-YZZA3 |

For the most accurate dipstick reading, check the level on flat, level ground after the engine has rested a few minutes.
What Oil Does the 2024–2027 Lexus GX 550 Take?
GX 550 Oil Capacity and Specification
The 2024 through 2027 Lexus GX 550 takes 7.7 quarts (7.3 liters) of SAE 0W-20 full synthetic motor oil during a standard oil and filter service. Every grade uses the same 3.4-liter twin-turbo V6, as Lexus confirmed again in its 2027 GX announcement.
A twin-turbocharged engine asks more of its oil than a naturally aspirated V8 does. Turbocharger bearings spin at extreme speeds and run hot. For that reason the GX 550 requires oil meeting the API SP or ILSAC GF-6A standard. Those formulations include additives that resist low-speed pre-ignition and thermal breakdown in forced-induction oil circuits.
The GX 550 Does Not Use the GX 460 Filter
This is the detail most GX owners get wrong. The V8 uses a cartridge element inside a reusable housing. The V35A-FTS does not. It uses a conventional spin-on canister filter, Genuine Lexus part number 90915-10010, shared with the LS 500 and LX 600. There is no cartridge element, no filter cap, and no housing drain plug on this generation. A cartridge kit ordered for a GX 550 will not fit.
| GX 550 Service Specification | Value |
|---|---|
| Oil capacity — with filter change | 7.7 qt (7.3 L) |
| Recommended viscosity | SAE 0W-20 full synthetic |
| Oil quality standard | API SP / ILSAC GF-6A |
| Oil filter design | Spin-on canister |
| Oil filter (OEM) | 90915-10010 |
| Same filter also fits | Lexus LS 500, Lexus LX 600, Toyota Tundra, Toyota Sequoia |

Fill to the upper mark on the dipstick and avoid overfilling. Too much oil can aerate and reduce pump priming efficiency.
Approved Oil Grades and Viscosities for the Lexus GX
SAE 0W-20 full synthetic is the specified viscosity grade for both the GX 460 and the GX 550. The low-temperature rating matters most at startup. At that moment 0W-20 reaches the upper cylinder heads quickly and gets oil to the variable valve timing actuators before they run dry.
Early 2010 GX 460 owner’s manuals listed broader alternative grades, including SAE 5W-30. Later model years standardized on SAE 0W-20. That is the grade to use today.
If 0W-20 is unavailable for an emergency top-off, SAE 5W-20 may be used temporarily. It must be replaced with SAE 0W-20 at the next service.
Primary Grade
SAE 0W-20 full synthetic, for both generations
Emergency Substitute
SAE 5W-20, replaced with 0W-20 at the next service
GX 460 Standard
ILSAC multigrade 0W-20
GX 550 Standard
API SP / ILSAC GF-6A

Lexus GX Oil Change Intervals
Under normal driving, Lexus sets a 10,000-mile or 12-month oil and filter interval, whichever comes first. That applies to both the GX 460 V8 and the GX 550 twin-turbo V6. The full synthetic requirement is what makes the longer interval possible.
Special operating conditions cut the interval in half. Lexus defines those conditions as frequent short trips under 5 miles, sustained sub-freezing driving, towing, heavy idling, and regular driving on dusty or unpaved roads.
| Driving Conditions | Oil & Filter Change Interval |
|---|---|
| Normal driving | Every 10,000 miles or 12 months |
| Special operating conditions — short trips under 5 miles, sub-freezing driving, towing, heavy idling, dusty or unpaved roads | Every 5,000 miles or 6 months |

Drivers in Temecula, Murrieta, and Menifee who tow, idle in traffic, or run unpaved roads should plan on the 5,000-mile schedule. To see how this fits the rest of your service cadence, review the full Lexus maintenance schedule.

Frequently Asked Questions About Lexus GX Engine Oil
How much oil does a 2010–2023 Lexus GX 460 oil change require?
A standard oil change with a new filter element requires 8.2 quarts (7.8 liters) of SAE 0W-20 full synthetic motor oil. Without replacing the filter, the fill volume is 7.8 quarts (7.4 liters).
What happens if I use 5W-30 in my Lexus GX 460?
Early 2010 manuals listed 5W-30 among allowable grades, but later Lexus specifications standardized on SAE 0W-20 full synthetic. Heavier grades slow oil delivery to variable valve timing components during cold starts.
What oil capacity and viscosity does the twin-turbo GX 550 require?
The 3.4-liter twin-turbo V6 takes 7.7 quarts (7.3 liters) of SAE 0W-20 full synthetic oil meeting the API SP or ILSAC GF-6A standard when the oil and filter are replaced together.
Does the Lexus GX use a cartridge oil filter or a spin-on filter?
It depends on the generation. The GX 460 uses a cartridge element inside a reusable housing, with a drain plug on the cap that lets a technician empty the filter cavity before removal. The GX 550 uses a conventional spin-on canister filter instead.
How often should I change the oil under severe driving conditions?
Lexus shortens the interval to every 5,000 miles or 6 months under special operating conditions, including towing, frequent short trips under 5 miles, heavy idling, and driving on dusty or unpaved roads.
