Land Rover STJLR.51.5122 Oil Specification

The Land Rover STJLR.51.5122 oil quality specification started being used in the USA by Land Rover in 2015. Currently the Land Rover STJLR.51.5122 oil specification is being used in the 2015 onward Land Rover 5.0L V8 and 3.0 Liter V6 gasoline engines. This oil quality specification correlates to the ACEA C5 oil specification and is a SAE 0W-20 viscosity. The 5W-20 viscosity is also in accordance with the Land Rover STJLR.51.5122 specification. However, the SAE 5W-20 viscosity can be difficult if not impossible to find. The availability of this oil will depend on your region. Land Rover STJLR.51.5122 is a lower viscosity oil grade with a Mid SAPS (Mid Sulphated Ash Phosphorus Sulfur) additive level formulation. It is engineered for improved fuel economy and extended oil change intervals. Any oil claiming to meet Land Rover STJLR.51.5122 should have a minimum HTHS viscosity of 2.6 mPa*s.

日本国内ではCastrol EDGE professional E 0w-20が純正採用されています。1L3500円くらいっぽい。professionalと付くのはディーラー専売商品なので一般ルートでは手に入りません。
