Complete Oil Specifications
Your 2024 Lexus RX 350 2.4L Turbo requires 0W-20 full synthetic oil meeting API SP and ILSAC GF-6A standards. Lexus replaced the naturally aspirated 3.5L V6 with the T24A-FTS turbocharged 4-cylinder for the fifth-generation RX starting in 2023. This newer engine delivers more power (275 hp vs. 295 hp) with improved fuel economy, and its direct-injection turbocharged design requires the enhanced LSPI protection of API SP / GF-6A certified oil.

Why 0W-20 is Critical for This Engine
The T24A-FTS uses Toyota’s D-4ST dual-injection system (direct + port injection), a twin-scroll turbocharger, and Dual VVT-i variable valve timing on both intake and exhaust camshafts. The 0W-20 viscosity allows the oil to reach the twin-scroll turbocharger’s center housing within seconds of cold start — preventing the carbon deposits and bearing wear that occur when heavier oils are slow to reach turbo bearings. API SP / GF-6A certification is mandatory for LSPI prevention in turbocharged direct-injection engines.
Using incorrect oil will:
- ❌ Delay turbocharger oil supply at cold start, accelerating bearing wear
- ❌ Increase LSPI risk if a non-GF-6A certified oil is used
- ❌ Reduce fuel economy gains from the T24A-FTS’s direct-injection efficiency

Pro Tip: After the first 5,000 miles with a new or rebuilt T24A-FTS engine, inspect oil color on the dipstick — any metallic sheen warrants immediate inspection, as the turbocharger break-in period is critical.
FAQs
What oil does a 2024 Lexus RX 350 2.4L Turbo take? 0W-20 full synthetic oil meeting API SP and ILSAC GF-6A standards.
How many quarts does it need? 5.4 quarts with a new filter, 5.1 without.
Is the oil spec the same as the 2023 RX 350 2.4L Turbo? Yes — the T24A-FTS engine in the 2023 and 2024 RX 350 uses identical oil specifications.
Can I still use 0W-20 from the older 3.5L V6 era? API SP oils are backwards compatible with older API SN oils. Any API SP / GF-6A 0W-20 is suitable for the 2024 RX 350.
How often should I change the oil? Every 10000 miles for normal driving, or 5000 miles for severe service.
