Synthetic Technosynthese® lubricant specially designed for conventional cars, powered by Gasoline and Diesel engines, naturally aspirated or turbocharged, indirect or direct injection, carburettor or injection, with or without catalytic converter.
Suitable for many types of fuels: leaded or unleaded Gasoline, LPG & Diesel.
Compatible for catalytic converters.

MOTUL 4100 PROTECT 10W-40 provides improved deposit protection for increased engine cleanliness. Its viscosity grade SAE 10W-40 is fully suitable for many Gasoline and Diesel engines working in all climate conditions and is designed to allow reduced oil consumption.
The standard API SL is more stringent than API SJ in terms of ageing resistance (average drain interval increased), requires anti-oxidation properties that maintain a constant viscosity avoiding sludge and deposits in the crankcase, anti-wear properties and dispersant power, and fuel economy benefits.
The reinforced synthetic Technosynthese® base stock provides very high lubricating power which reduces frictions, decreases the volatility and ensures resistance to very high temperatures reached in modern engines.

Drain interval: according to manufacturers’ recommendations and tune to your own use.
Can be mixed with synthetic or mineral oils.
Before use or if in doubt, always refer to the owner manual or handbook of the vehicle.
