Motul 8100 X-clean 5W-40 Full Synthetic Motor Oil 5L — Mid-SAPS, ACEA C3 for DPF & Turbo Engines

Motul 8100 X-clean 5W-40 is a 100% synthetic mid‑SAPS motor oil formulated to protect modern emission systems while delivering stable lubrication for gasoline and diesel engines.

Developed from Motul's motorsport heritage, the 8100 X-clean line adapts race‑proven additives and base oils to everyday driving. This 5W‑40 formulation targets contemporary European and global engines that require ACEA C3 or GM dexos2 performance, balancing emission‑system compatibility with strong wear and thermal protection for long service intervals.

How does this oil support emission control systems?

Motul 8100 X-clean uses a Mid‑SAPS additive strategy that reduces ash, phosphorus and sulfur buildup, helping catalytic converters and diesel particulate filters operate more effectively over time. The lower contaminant load helps preserve after‑treatment efficiency without sacrificing lubricity.

• Mid‑SAPS chemistry designed for DPF and catalytic converter compatibility
• Reduced deposit formation to help maintain filter performance
• ACEA C3 accreditation for after‑treatment system requirements

Will it protect my engine in high temperatures and under load?

This full synthetic 5W‑40 delivers strong film strength and oxidation resistance to withstand elevated operating temperatures and heavy loads such as towing or spirited driving. Its formulation resists viscosity breakdown, helping maintain oil pressure and clearances in turbocharged and high‑output engines.

• High thermal stability to limit viscosity loss
• Enhanced anti‑wear additives for critical bearings and cams
• Suitable for turbochargers and modern direct‑injection engines

Which vehicles and specifications is Motul 8100 X-clean compatible with?

The oil meets a broad set of OEM and industry standards, making it compatible with many European cars and other vehicles specifying 5W‑40 C3 oils. It satisfies Mercedes‑Benz, Renault, VW, Fiat, Chrysler, Ford and GM dexos2 requirements listed by manufacturers that accept ACEA C3 performance.

• Meets ACEA C3 and GM dexos2 performance levels
• Approved to Mercedes‑Benz 229.51, Renault RN0700 / RN0710, VW 505 00 / 505 01
• Also suitable for many BMW, Audi, Volkswagen, Renault, and Fiat engines requiring 5W‑40

How does this oil help with maintenance intervals and engine cleanliness?

Formulated to limit sludge and deposit formation, Motul 8100 X‑clean helps engines stay cleaner over extended drain intervals when combined with the manufacturer's recommended service schedule. Stable viscosity and oxidation control reduce the rate of oil degradation, supporting durable performance between changes.

• Resists sludge and varnish to keep oil passages cleaner
• Oxidation inhibitors extend useful oil life under typical conditions
• Designed for long‑term engine protection when service intervals are followed

Who is this for: Motul 8100 X‑clean 5W‑40 is aimed at owners of modern gasoline and diesel vehicles — particularly European makes — that require ACEA C3 or dexos2 oils and need a balance of emission‑system compatibility and robust engine protection. Choose this 5L pack if you want a full synthetic mid‑SAPS oil for turbocharged or high‑output engines, long drains when permitted by the manufacturer, and broad OEM acceptance.
