Complete Oil Specifications
Your 2023 Lexus LX 600’s 3.5L V35A-FTS twin-turbo V6 requires 0W-20 full synthetic oil meeting API SP and ILSAC GF-6A standards. The V35A-FTS is a high-output, twin-turbocharged engine paired with a 10-speed automatic and multi-terrain crawl control — oil quality and capacity are critical for both on-road performance and off-road thermal management.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 0W-20 |
| API Rating | SP |

| Capacity (with filter) | 7.0 quarts |
| Oil Filter | Toyota 04152-YZZA4 |
| Normal Interval | 10000 miles |
Why 0W-20 is Critical for This Engine
The V35A-FTS uses Toyota’s D-4ST dual-injection system (both port and direct injection), twin turbochargers, and VVT-iW variable valve timing on the intake camshaft. Cold-start lubrication of twin turbo bearing housings is critical within the first seconds of startup. 0W-20’s low cold-flow resistance reaches turbo bearings faster than heavier grades, and its GF-6A certification ensures LSPI (low-speed pre-ignition) protection for the turbocharged direct-injection combustion system.
Using incorrect oil will:
- ❌ Increase turbocharger bearing wear during cold starts
- ❌ Potentially trigger LSPI events in a turbocharged DI engine with wrong additive chemistry
- ❌ Reduce fuel economy measurably on the combined cycle
Lexus-Approved Oil Brands
-
✅ Toyota/Lexus Genuine Motor Oil 0W-20
-

Severe Service Check
You need the 5000-mile interval if you:
- Tow at or near the 8,000 lb rated capacity regularly
- Use the LX 600 for sustained off-road driving with crawl control
- Operate in ambient temperatures consistently above 100°F
- Drive in sand or deep mud conditions regularly
Installation Details
Drain Plug Torque: 30 ft-lbs
The LX 600 uses a steel oil pan with a reusable drain plug gasket — inspect the gasket for deformation and replace if necessary. Lexus recommends replacing the gasket every other oil change.
OEM Filter: Toyota 04152-YZZA4
Aftermarket Filters:
-
Mobil 1 M1C-453A
-
K&N HP-1015
-
Fram XG10575
Pro Tip: The LX 600 has a cartridge-style oil filter element inside a housing mounted on the front of the engine block. Use a 64 mm cap wrench to avoid cracking the plastic housing.
FAQs
What oil does a 2023 Lexus LX 600 take? 0W-20 full synthetic oil meeting API SP and ILSAC GF-6A standards.
How many quarts does it need? 7.0 quarts with a new filter, 6.6 without.
Can I use 5W-30 if 0W-20 isn’t available? Toyota does not recommend substituting a heavier grade. In an emergency, 5W-30 API SP is an acceptable temporary fill, but switch back to 0W-20 at the next service.
Is full synthetic required? Yes — API SP and ILSAC GF-6A are full-synthetic specifications for turbocharged engines.
How often should I change the oil? Every 10000 miles for normal driving; every 5000 miles for towing or sustained off-road use.
