Engine oil Motul 8100 X‑Clean 5W40 — fully synthetic motor oil, 4 L

Motul 8100 X‑Clean 5W40 is a fully synthetic 4 L engine oil developed for modern gasoline and diesel engines. With SAE viscosity 5W‑40, this formulation delivers consistent lubrication, thermal stability and wear protection across a wide temperature range. It is intended for vehicles requiring a 5W‑40 grade and provides compatibility with engines fitted with exhaust aftertreatment systems when specifications permit.

Advantages

The fully synthetic base and tailored additive package ensure sustained film strength, reduced friction and protection against engine wear and deposits. The oil maintains viscosity at high temperatures for reliable lubrication during highway driving and heavy load conditions, while retaining flowability at low temperatures for improved cold starts. Formulation supports oil durability and helps preserve engine cleanliness under varied operating conditions.

Suitable for

• Modern gasoline engines
• Modern diesel engines
• Everyday city driving and long-distance touring
• Engines requiring SAE 5W‑40 viscosity

Key specifications

• Viscosity grade: SAE 5W‑40
• Fully synthetic formulation
• Volume: 4 litres
• Optimised viscosity-temperature behaviour for cold starts and high-temperature protection
• Designed to limit deposit formation and reduce wear

How to use

Use Motul 8100 X‑Clean 5W40 where the vehicle manufacturer recommends a 5W‑40 synthetic oil. Before adding oil, check the current oil level and condition using the dipstick or electronic indicator with the engine stopped and on level ground. Pour the oil slowly into the filler neck, monitoring the level until it reaches the recommended mark. After refilling, run the engine briefly and recheck the level when the engine is warm, topping up if necessary according to the manufacturer’s specified capacity and service intervals.

Usage recommendations

Follow the vehicle manufacturer’s instructions for oil change intervals and specified viscosity grades. Replace the oil filter during each oil change and dispose of used oil in accordance with local regulations. If the vehicle is under warranty, confirm compatibility with the manufacturer’s requirements before use.
