Complete Oil Specifications
Your 2022 Lexus IS 300 with the 2.0T 8AR-FTS engine requires 0W-20 full synthetic oil meeting API SP / ILSAC GF-6A. The 8AR-FTS is Toyota/Lexus’s turbocharged direct-injection four-cylinder, featuring both port injection and direct injection (D-4ST) — a system that reduces carbon buildup on intake valves while maximizing power output.
Quick Reference

|---|---|
| Viscosity | 0W-20 |
| API Rating | API SP |
| ILSAC Rating | GF-6A |
| Capacity (with filter) | 4.9 quarts |
| Oil Filter | Toyota/Lexus 90915-YZZD1 |
| Normal Interval | 10000 miles or 1 year |
Why 0W-20 for the 8AR-FTS Turbo
The 8AR-FTS combines a twin-scroll turbocharger with Toyota’s D-4ST dual-injection system and Dual VVT-iW (intake and exhaust variable valve timing). Both the turbo shaft bearings and the VVT-iW hydraulic actuators depend on rapid oil pressurization at startup. Toyota specifies 0W-20 to minimize startup friction and deliver fast oil flow to the turbo, which can accelerate to 200,000 RPM under load — a condition where even seconds of oil starvation causes premature wear.
Using incorrect oil will:
- ❌ Delay turbo bearing lubrication at cold start, shortening turbo life
- ❌ Slow VVT-iW phaser actuation, causing rough idle and timing instability
- ❌ Increase LSPI risk without the GF-6A anti-LSPI chemistry
Lexus-Approved Oil Brands
-
✅ Lexus Genuine Motor Oil 0W-20
-
✅ Toyota Genuine Motor Oil 0W-20
-
✅ Mobil 1 Extended Performance 0W-20
-
✅ Pennzoil Ultra Platinum Full Synthetic 0W-20
-
✅ Castrol Edge Full Synthetic 0W-20
All oils must carry the API SP / ILSAC GF-6A starburst. The GF-6A standard’s anti-LSPI chemistry is particularly important for this turbocharged direct-injection engine.
Severe Service Check
Use the 5000 schedule if you:
- Frequently drive in Sport S+ mode or use paddle shifters at high RPM
- Make short trips under 5 miles where the turbo never fully cycles
- Operate in extreme cold below −4°F, where turbo heat-soak on shutdown is more damaging
- Drive in stop-and-go urban traffic that generates short-cycle turbo loads
Installation Details
Drain Plug Torque: 30 ft-lbs
Replace the aluminum crush washer at every change. The IS 300 uses the standard Toyota/Lexus drain plug specification.
OEM Filter: Toyota/Lexus 90915-YZZD1
Aftermarket Filters:
-
Mobil 1 M1-110A
-
WIX 57082XP
-
K&N HP-1014
Pro Tip: After an oil change, let the IS 300 idle for 60 seconds before driving — this allows the turbo bearings to fully pressurize. Avoid hard acceleration for the first mile when the oil is cold.
FAQs
What oil does a 2022 Lexus IS 300 take?
0W-20 full synthetic meeting API SP / ILSAC GF-6A.
How many quarts does the IS 300 2.0T need?
4.9 quarts with a new filter, 4.7 without.
Can I use 5W-30 for better turbo protection?
No. Lexus specifies 0W-20 for the 8AR-FTS. Modern 0W-20 full synthetics provide sufficient turbo protection. If you’re concerned, shorten your interval rather than increasing viscosity.
Is synthetic oil required?
Yes. The 8AR-FTS turbo requires full synthetic to meet API SP / GF-6A and achieve the 10,000-mile interval.
How often should I change the oil?
Every 10000 for normal driving. Use 5000 for frequent short trips or spirited driving.
