GM dexos1™ oils are robust durable high-performance lubricants which enable modern, fuel efficient gasoline engines to reach peak efficiency.
GM dexos1™ oils are typically low HTHS SAE 0W-20, 5W-20, 0W-30 and 5W-30 based on API Group II, Group III or Group IV base oils.
The main physical and chemical requirements for GM dexos1™ oils are shown below:
|HTHS viscosity||CEC L-36-A-90||cP||≥ 2.6 (0W-20, 5W-20)
≥ 2.9 (0W-30, 5W-30)
|Sulphated Ash||ASTM D874||%wt||≤ 1.0|
|Phosphorus||ASTM D4951||mg/kg||< 850|
|Sulphur||ASTM D4951||mg/kg||< 4500|
|Evaporation loss (NOACK)||CEC L-40-A-93||%||≤ 13.0|
|Total Base Number||ASTM D2896||mgKOH/g||≥ 6.0|
GM dexos1™ is usually coupled with API SN PLUS, API SN and ILSAC GF-5.
