ACDelco 5W-30 Full Synthetic Motor Oil dexos1 Gen 2 — 1 Qt Bottles (8-Pack) for Gasoline Engines, Wear Protection

ACDelco 109246 SAE 5W-30 dexos1 Gen 2 is a full synthetic engine oil supplied in one-quart bottles (sold as an 8-pack) engineered to meet modern gasoline engine requirements and protect components under varied driving conditions.

This offering from ACDelco is a full synthetic 5W-30 motor oil formulated to satisfy dexos1 Gen 2 specifications for many gasoline-powered GM and non-GM vehicles. Packaged as eight separate one-quart bottles, the product is convenient for DIY oil changes and small shop use. Note: GM discontinued the 10-9246 part number and replaced it with 10-9329 — performance intent remains consistent with dexos1 Gen 2 standards.

What does dexos1 Gen 2 certification mean for my engine?

dexos1 Gen 2 is a modern performance specification developed to address fuel economy, deposit control, and wear protection in contemporary gasoline engines. Oils meeting this spec have passed tests for oxidation resistance, sludge and varnish control, and timing chain wear, making them suitable for many late-model cars.

• Designed for gasoline engines requiring dexos1 Gen 2 performance
• Balances fuel economy with protection under high stress
• Undergoes industry-standard lab and engine tests

How does 5W-30 viscosity help in everyday driving?

5W-30 indicates the oil’s cold-start flow (5W) and operating thickness at engine temperature (30). This grade offers reliable cold-weather startability while maintaining a protective film at normal operating temperatures, suitable for a wide temperature range and typical driving patterns.

• Improves cold starts with lower winter viscosity
• Maintains protective viscosity at highway and city operating temperatures
• Commonly recommended in owner manuals for many modern gasoline engines

Why choose a full synthetic oil instead of conventional or blend?

Full synthetic oils are engineered molecules that offer more consistent protection across temperature extremes and resist breakdown longer than conventional oils. For drivers seeking extended protection, cleaner operation, and stable viscosity over longer intervals, a full synthetic like this provides measurable advantages.

• Better resistance to oxidation and thermal breakdown
• Reduced engine deposits and improved cleanliness
• Generally supports longer drain intervals when permitted by the manufacturer

How is the 8-pack format useful for owners and shops?

Buying this product as an eight-quart pack is practical for those who service multiple vehicles or prefer stocking a single-grade oil for convenience. It simplifies maintenance scheduling and ensures you have the correct dexos1 Gen 2 5W-30 supply on hand when performing oil changes.

• One-quart bottles allow mixing and topping off without waste
• Cost-effective for frequent DIY maintenance or small service bays
• Easy to store and transport compared with larger drums
