Recent GM-OPEL engines compliant with Euro 4, 5 and 6 emission regulations are fitted with very sensitive exhaust gas after treatment systems. Indeed, Sulfur and Phosphorus inhibit catalytic converters (CAT) operation leading to inefficient exhaust gas treatment; and Sulfated Ash clog Diesel Particulate Filters (DPF) leading to shorten regenerating cycle, quick oil aging, higher fuel consumption and engine power loss.
GM-OPEL for its dexos2^TM norm requires oil to able to endure the most severe thermal constrains along with modern after treatment systems compatibility. Compare to the old GM-LL-A-025 & GM-LLB-025 standards, this induced for the oil to be "Mid SAPS" formulated, with reduced contents of Sulfated Ash, Phosphorus and Sulphur, for longer preservation of after treatment systems such as CATs and DPFs.
GM-OPEL has developed its dexos2^TM 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.
dexos2^TM standard is suitable for the whole range of GM-OPEL Diesel engines (including DPF versions) and most of Gasoline engines from Model Year 2010. Also, dexos2^TM fully supersedes and replaces the previous GM specifications : GM-LL-A-025 (Gasoline) and GM-LL-B-025 (Diesel).
MOTUL SPECIFIC dexos2^TM 5W-30 meets all these highly demanding requirements of performance and durability set by GM-OPEL, including in particular for dexos2^TM standard, the full compatibility to biofuels use such as LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas), biodiesel (as available at the station) and bioethanol, when using bioethanol at a mix ratio of up to 85% (Bioethanol – E85).
