Dexos 1 and Dexos 2
Dexos is General Motors Corporation (GM) international standard for engine oils suitable for use in their ranges of fuel-efficient, low emission engines. GM licenses several oil companies to make and sell Dexos oil based on their specifications.
Dexos™ 1 is for gasoline engines meeting ILSAC GF-5 Resource Conserving specifications. This has recently been updated to Dexos™ 1 GEN 2 for even better engine protection particularly against LSPI (Low Speed Pre Ignition) in GM vehicles.
Dexos™ 2 is for Diesel and some gasoline vehicles and meets Low SAP requirements* for vehicles fitted with exhaust treatment devices such as DPFs (Diesel Particulate Filters).
