Complete Oil Specifications
Your 2023 Land Rover Range Rover Sport 3.0L Ingenium P400 requires 0W-20 full synthetic oil certified to the Jaguar Land Rover STJLR.51.5122 (SLX-Professional) specification. The third-generation Range Rover Sport uses the same Ingenium I6 MHEV architecture as the Defender P400 — do not confuse capacity or filter numbers with the outgoing AJ126 supercharged V6 that preceded it.

Why 0W-20 is Critical for This Engine
The Ingenium I6 features a twin-scroll turbocharger, dual variable camshaft timing, and a 48V integrated starter-generator that restarts the engine dozens of times per typical drive cycle. Each restart is a brief cold-start event, and 0W-20’s rapid flow at low temperature minimises the lubrication gap in those moments. The STJLR.51.5122 specification also mandates a low-SAPS additive package to protect the three-way catalytic converters fitted to meet Euro 6d standards.
Using incorrect oil will:
- ❌ Increase cam and bearing wear during repeated MHEV stop-start events
- ❌ Underfill the engine if using capacity figures for the old AJ126 V6
- ❌ Risk GPF/catalyst contamination with high-ash non-STJLR oils
Land Rover-Approved Oil Brands
-
✅ Castrol EDGE Professional Longlife IV FE 0W-20
-
✅ Mobil 1 ESP X2 0W-20
-
✅ Shell Helix Ultra Professional AV-L 0W-20
-
✅ Pennzoil Platinum Full Synthetic 0W-20
-
✅ Liqui-Moly Special Tec F ECO 0W-20
Always verify the STJLR.51.5122 approval appears on the container. Generic 0W-20 oils without this certification may not provide adequate MHEV stop-start protection.
Severe Service Check
You need the 8000-mile interval if you:
- Tow a trailer or horse box regularly
- Use the Dynamic or Sport driving modes frequently in hot weather
- Drive in heavy stop-and-go urban traffic daily
- Operate in extreme dust or high-altitude conditions

Pro Tip: Oil consumption of up to 0.5 qt per 1,000 miles is within JLR’s normal tolerance for the P400 under hard driving. Check the level at every fill-up during the first 10,000 miles of ownership.
FAQs
What oil does a 2023 Land Rover Range Rover Sport 3.0L P400 take? 0W-20 full synthetic oil certified to STJLR.51.5122 (SLX-Professional).
How many quarts does it need? 9.3 quarts with a new filter, 8.8 without.
Is this the same oil as the older Range Rover Sport V6? No. The AJ126 supercharged V6 used a different viscosity and took considerably fewer quarts. The Ingenium I6 P400 requires 0W-20 STJLR.51.5122, not 5W-30.
Is full synthetic required? Yes — the STJLR.51.5122 specification is full-synthetic only.
How often should I change the oil? Every 16000 miles normally; 8000 miles under towing or sustained performance driving.
