Motul 8100 X-CLEAN+ is a 100% synthetic, low-SAPS oil built around the ACEA C3 specification for modern direct-injection gasoline and diesel engines, including those fitted with a diesel particulate filter or three-way catalyst. The 5W-30 grade targets the European fleet covered by the BMW, Mercedes-Benz, Volkswagen Group, and Porsche approvals listed below, rather than general-purpose fitment — check that your engine actually calls for one of these approvals before buying.

Is this oil compatible with your car?
Viscosity alone does not determine whether an oil is right for your engine. Compatibility depends on the exact OEM approval your manufacturer requires, your engine's build, the model year, and the market the car was sold in — the same nominal viscosity can carry different approvals in different regions. Check your owner's manual or use OilFinderPro below to confirm the requirement for your specific vehicle before buying.
Oils sharing one or more specifications
Each row shows the exact specification two products share and whether it is a formally licensed approval or a lighter "meets requirements" claim on each side — those are not equivalent, and sharing a specification does not by itself make two oils interchangeable in your vehicle.
