The API SN standard is fully backward compatible over API SM standard and all former API standards.
API SN lubricants provide outstanding oxidation resistance, better anti-deposits protection, better engine cleanliness, anti-wear protection and enhanced performance at cold temperature for Fuel Economy savings during the whole oil life span.
Based on the API SN specification, the ILSAC GF-5 standard is even more severe especially on the energy saving criteria. The requirements on the low viscosity "Fuel Economy" side of the lubricant, but also extended drain intervals, clean pistons/rings, seals compatibility and reduced content of
phosphorus for after treatment systems compatibility are enhanced. The ILSAC GF-5 specification ensures perfect engine protection when gasoline containing up to 85% Ethanol is used (E85). GM dexos1' standard is suitable for the whole range of GM Gasoline engines from Model Year 2011
onwards requiring an approved dexos1 lubricant (except for service fill in Europe). Specification GM dexos1' is designed for use with gasoline engines and replaces GM-LL-A-025, GM 6094M and GM 4718M. GM dexos1' is also backward compatible for pre-2011 GM gasoline vehicles.
GM dexos1' standard combines very stringent requirements from international standards like API, ACEA and ILSAC, together with specific GM requirements to prove Fuel Economy benefits and engine durability.
GM has developed its dexos1' standard in order for the oils to provide a high thermal stability and insure an outstanding resistance at high temperatures to avoid black sludge and viscosity increase that soot, coming from combustion residues, may create.
Turbocharged gasoline engines with direct injection have a certain risk of sporadic pre-ignition phenomena in the combustion chambers. This type of sporadic abnormal combustion resembles metallic noise from combustion chambers and is sometimes associated with a short power loss.
This phenomenon called LSPI for Low Speed Pre-Ignition, or also Rumble, generates very high pressure peaks in the combustion chamber that can lead to piston damages and ultimately to engine destruction. For their latest-generation downsized gasoline engines, which are equipped with direct injection systems and turbochargers, GM has developed the dexos1' GEN2 standard for engine lubricants in order to guarantee the perfect integrity of these gasoline engines facing the risk of these abnormal combustions.
MOTUL 8100 Eco-lite 5W-30 meets all these very highly demanding requirements of performance and durability set by GM, including in particular for dexos1' standard, the full compatibility to biofuels use such as LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), and bioethanol (as available at the station), when using ethanol biofuel at a mix ratio of up to 85% (Bioethanol E85).
Some OEMs require for their most recent Gasoline engines an API SN and/or ILSAC GF-5 lubricant to guarantee the maximum performance and durability. The CHRYSLER specification MS6395 (GF-4 level), FORD M2C 929-A (GF-4 level) and FORD M2C 946-A (GF-5 level) reflect these kind of requirements. Other examples of MOTUL 8100 Eco-lite 5W-30 possible use for these OEMs looking for Fuel Economy: HONDA, SUBARU and TOYOTA gasoline engines. MOTUL 8100 Eco-lite 5W-30 provides high lubricating properties such as wear protection and high temperature resistance for better controlled oil consumption, improves oil flow at start up for faster oil pressure build up, faster rev raisings, faster operating temperature reach and fuel economy benefits.
Environment friendly, this type of oil allows fuel consumption reduction and therefore minimizes greenhouse gases (CO2) emissions.
These oils may be unsuitable for use in some engines. Refer to the owner manual or handbook if in doubt.
