Engines compliant with Euro 4, 5 and 6 emission regulations are fitted with sensitive exhaust gas after treatment systems. Indeed, Sulfur and Phosphorus inhibit catalytic converters operation leading to inefficient exhaust gas treatment, and Sulfated Ashes clog DPFs leading to shorten regenerating cycle, quick oil aging, higher fuel consumption and engine power loss.
JLR - Jaguar and Land Rover, have introduced their own engine oil specifications under the STJLR banner and the FORD WSS-M2C934-B specification has now been morphed for Jaguar and Land Rover into the specification STJLR.03.5005.
The STJLR.03.5005 specification requires high level of oil film resistance, anti-oxidation, anti-wear and detergent/dispersant properties from the lubricant as well as a significant fuel economy performance: at least 3.0% Fuel Economy improvement versus a 15W-40 reference oil.
The STJLR.03.5005 specification applies to all JAGUAR and LAND ROVER latest generation of 2.2L TD4, 2.7L and 3.0L V6 Diesel engines with DPF produced from MY2012 and whenever the specification FORD WSS-M2C934-B is required from MY2006.
MAZDA recommendations require to use an approved JASO DL-1 or ACEA C1 lubricant in order to guarantee Fuel Economy benefits and a perfect durability for most of their recent Diesel with DPF engines from MY2005. For Mazda SKYACTIV-D 2.2L engines from MY2012 the specification ACEA C3 in viscosity grades 0W-30 or 5W-30 is required, the product MOTUL 8100 X-clean EFE 5W-30 is to be recommended.
ACEA C1 lubricants are environment friendly and reduce fuel consumption, minimizing green house gases (CO₂) emission and also achieve extended drain intervals managed by vehicles on-board computer.

Drain interval: according to manufacturers’ recommendations and tune to your own use.
Do not mix with non ACEA C1 compliant lubricants.
Before use always refer to the owner manual of the vehicle.
