It is a special oil for 4T outboard gasoline and diesel engines. It is a motor oil specially designed by Technosynthese® technology for 4-stroke outboard and rear engines: BOMBARDIER, HONDA, MARINER, MERCURY, SELVA, SUZUKI, TOHATSU, YAMAHA. It is recommended to use it in lead-free fuel. FC-W standard is specially developed for the oils used in the engines of water vehicles. This standard sets more stringent requirements than the standard for water engines in terms of the following values: higher HTHS values – high-temperature viscosity to guarantee better oil film strength in high temperatures and absorb fuel in the oil; better resistance to shear in high temperatures; excellent anti-corrosive properties to neutralize impact of sea salty water and impact in winter time; retention of high performance in case of dirty sea water; better protection from oxidation; anti-foaming properties to reduce air impact during oil circulation; better protection from oil filter clogging.
