Purpose and Specifications

Power your engine with MOTUL 4100 SYN-NERGY 10W40 4L, a premium Technosynthese synthetic oil that delivers top protection for petrol and diesel cars, including turbocharged and direct injection models from European brands like Mercedes, Renault, VW, and PSA. This 4-liter pack flows smoothly for easy cold starts down to -25°C, while staying thick and strong up to 150°C under heavy loads, slashing friction and preventing low-speed pre-ignition (LSPI) damage.

Meets tough standards like ACEA A3/B4, API SP/CF, MB 229.3, Renault RN0710/RN0700, and VW 501.01/505.00, offering 1.2% better fuel savings than thicker oils and extended drain intervals via your car's computer. Works with all fuels including ethanol, LPG, diesel, and biofuels, plus it's safe for catalytic converters.
