OEM Warranty Compliance for Jaguar Land Rover: Carries the official Jaguar Land Rover STJLR.51.5122 approval, the exact motor oil specification required for warranty-compliant service on 3.0L Supercharged V6 and 5.0L Supercharged V8 gasoline engines found in Range Rover Sport, Range Rover, Discovery, LR4, F-Type, F-Pace, XE, XF, and XJ , a premium aftermarket alternative to dealer-exclusive oils with the same OEM certification Cold Start Timing Chain Protection: The 0W-20 viscosity ensures rapid oil flow and pressurization during cold starts, delivering critical lubrication to timing chain tensioners within seconds of ignition, the primary wear concern for JLR supercharged gasoline engines where insufficient oil film at startup leads to tensioner wear and chain stretch over time, particularly in climates with sustained sub-freezing temperatures Fuel Economy Exceeding 3.8% Energy Savings: Formulated with a very low HTHS viscosity ranging from 2.6 to 2.9 mPa·s that reduces hydrodynamic friction across all operating temperatures, delivering measurable energy savings exceeding 3.8 percent as verified through ACEA A5/B5 engine test sequences — also backward compatible with the older Ford WSS-M2C925-A specification for JLR vehicles transitioning to the STJLR.51.5122 standard Mid SAPS Emissions System Compatibility: Mid SAPS formulation with reduced Sulfated Ash, Phosphorus, and Sulfur content protects modern catalytic converters while meeting Euro 4, 5, and 6 emission regulations — the robust additive package with high calcium, phosphorus, and zinc delivers wear resistance, thermal stability, and oxidation control at sustained operating temperatures for the car engine across extended service intervals 100% Synthetic Base Stock from French Heritage Manufacturer: 100 percent synthetic base oil formulated by Motul, an independent French lubricant manufacturer established in 1853 with deep motorsport heritage. ACEA C5 certified and specifically designed for the latest generation Jaguar Land Rover gasoline engines requiring the STJLR.51.5122 standard, delivering the same specification and approval as factory-fill oils available exclusively through authorized dealerships
