ACDelco dexos1 Fully Synthetic Engine Oil

ACDelco OW20 Dexos1 Gen 2 Fully Synthetic Engine Oil is a resource conserving, multigrade gasoline engine oil formulated with synthetic base oils for use in passenger car and light truck engines requiring low viscosity, ILSAC GF-5 or API SN PLUS.



  • Preserves and protects engines
    Proven metallo-organic anti-wear additive system protects engines under all operating conditions by providing excellent wear control in even the most sophisticated valve train mechanisms, including those with variable valve timing. Low viscosity, multigrade, formulation provides additional protection reduces internal engine friction. Enhanced corrosion protection ensures compatibility with gasoline/ethanol blended fuels up to and including E85.

  • Maintains high power and performance
    Works immediately upon contact with an engine’s moving parts to create a protective coating that shields the engine against the deposits that lead to loss of performance. Provides excellent control of piston and ring deposits under high temperature conditions. Special friction modifiers assist in reducing internal engine friction for maximum fuel economy.

  • Saves on maintenance costs
    High thermal stability and excellent oxidation resistance provides outstanding protection against in-service oil degradation that contributes to filter blocking and sludge formation in the oil galleries, crankcase and valve train.

  • Low oil consumption
    Low volatility, synthetic base oil minimizes oil loss through evaporation.

  • Reduces fuel consumption:
    Improved visco-metric properties, creating less friction in the engine, which contributes to improved fuel economy.

  • Extended drain intervals:
    Resists degradation between oil changes, extending the time and mileage interval between oil changes.
