FOSSER Premium LSPi tech 5W-30

High-performance low-friction engine oil

Properties

FOSSERPremiumLSPitech5W-30 is a modern, synthetic low-friction engine oil with low-SAPS technology, specially developed for gasoline and diesel engines in passenger cars. Thanks to its advanced additive technology, it is particularly suitable for vehicles equipped with exhaust aftertreatment systems. The oil stands out for its excellent cold-start properties as well as for reducing fuel consumption, friction, and wear. In addition, FOSSER Premium LSPi tech 5W-30 helps prevent low-speed pre-ignition (LSPI), thereby effectively protecting the engine from potential damage.

Application notes

FOSSERPremiumLSPitech5W-30 is ideal for fuel-efficient, year-round use in modern gasoline and diesel engines. It has been specifically developed for Stellantis engines and meets their specific requirements regarding performance and wear protection. FOSSER Premium LSPi tech 5W-30 is particularly recommended for engines that require the new Stellantis specification FPW9.55535/03. Oil change intervals may be extended in accordance with the manufacturer‘s guidelines.

FOSSER Garant Flex 20W-50

Maximum stability. Engine armor for high temperature and heavy-duty performance.

FOSSER Garant Flex 20W-50 is a high-performance multigrade oil based on proprietary FOSSER Flex technology, developed for engines exposed to extreme heat and continuous stress. The FlexMesh molecular network forms a three-dimensional structure that keeps the lubricating film stable up to +230 °C, resisting shear and evaporation.

Benefits:
• Stable high-temperature protection up to +230 °C
• FlexMesh: 3D molecular network for heat and load stability
• ZDDP + metal conditioners for wear and pressure resilience
• Improved piston-ring sealing – higher compression, lower oil consumption
• Constant oil pressure and viscosity (VI = 139) under sustained load
• Ideal for desert heat, stop-and-go driving, towing, and off-road use

* meets the requirements of the OEM manufacturer. The stated values may vary within the usual commercial range.
