Why 0W-20 is Critical for This Engine
The 2GR-FKS 3.5L V6 features Toyota’s D-4S dual injection system — combining port and direct fuel injection — alongside Dual VVT-iW variable valve timing on both intake and exhaust. This combination requires low-viscosity 0W-20 synthetic oil to ensure immediate lubrication of the variable valve timing actuators at cold start and to maintain the precision oil film tolerances demanded by the dual-injection combustion system.
Using incorrect oil will:
- ❌ Delay oil pressure to the VVT-iW system, causing rattling on cold start
- ❌ Reduce fuel efficiency on the Atkinson-cycle-capable engine
- ❌ Accelerate wear on the dual overhead camshaft timing chain
Lexus-Approved Oil Brands
-
✅ Lexus Genuine Motor Oil 0W-20
-
✅ Mobil 1 Extended Performance 0W-20
-
✅ Castrol Edge Extended Performance 0W-20
-
✅ Pennzoil Platinum Full Synthetic 0W-20
-
✅ Valvoline Advanced Full Synthetic 0W-20
Look for both the API SP donut and ILSAC GF-6A starburst certification marks on the oil container. Both confirm full synthetic protection at the correct viscosity for the 2GR-FKS.
Severe Service Check
You need the 5000-mile interval if you:
- Make frequent short trips under 5 miles in cold weather
- Drive in heavy stop-and-go urban traffic daily
- Operate in extreme heat above 100°F for extended periods
- Experience frequent cold starts in sub-freezing temperatures
Installation Details
Drain Plug Torque: 33 ft-lbs Replace the aluminum crush washer at every oil change. Reusing the old washer is a common cause of slow drain plug seepage.

Pro Tip: The 2GR-FKS uses a cartridge-style oil filter canister under the intake manifold. Access requires a long-reach 64mm filter cup wrench. Torque the canister cap to 18 ft-lbs. Pre-fill the cartridge with fresh oil before installation to minimize dry-start duration.
FAQs
What oil does a 2023 Lexus ES 350 take? 0W-20 full synthetic meeting API SP and ILSAC GF-6A standards.
How many quarts does the 2023 ES 350 hold? 6.8 quarts (approximately 6.4 liters) with a new filter, 6.3 quarts without.
Can I use 5W-20 in my ES 350? Lexus does not recommend it. 0W-20 is specified for optimal cold-start protection. Use 5W-20 only as an emergency stop-gap, and replace with 0W-20 at the next service.
Is synthetic oil required for the ES 350? Yes. Lexus factory-fills the 2GR-FKS with full synthetic and all subsequent changes must be full synthetic 0W-20.
How often should I change the oil on the ES 350? Every 10000 miles or 12 months for normal driving. Lexus’s Maintenance Reminder System will alert you when a change is needed based on actual driving conditions.
