Why I Chose Full Synthetic Oil
I’ve always heard that full synthetic oils provide better engine protection and performance, especially in extreme temperatures.

- Longer Oil Change Intervals: The durability of the synthetic formula allowed me to extend the time between oil changes without worrying about engine wear.
Compatibility and Vehicle Requirements
Before buying, I checked my owner’s manual to ensure 0W20 was the recommended viscosity grade. The Acdelco Gen 2 formulation is compatible with many modern gasoline engines, including those requiring dexos1 Gen 2 certification, which gave me confidence it would work well with my car.
Packaging and Size Options
I found that Acdelco offers this oil in various container sizes—from quarts to gallons—so I could buy exactly what I needed. For my regular maintenance, I went with a gallon jug, which was more economical and convenient.
