ACDelco Supercharger Oil 4 oz — GM OE Synthetic Lubricant for Bearings & Boost

ACDelco GM Original Equipment 10-4041 Synthetic Supercharger Oil (4 oz) is a GM OE-spec lubricant formulated to protect supercharger bearings and maintain reliable boost operation in supercharged engines.

This compact 4-ounce bottle delivers a concentrated, synthetic-grade fluid designed specifically for supercharged systems. Formulated to meet GM original equipment requirements, it helps reduce wear, resist oxidation, and keep internal supercharger components running smoothly across a wide range of temperatures. It’s intended for use in vehicles fitted with factory or aftermarket superchargers, and its small volume is convenient for service intervals, top-offs, or targeted maintenance jobs.

What exactly does this supercharger oil do for my engine?

The oil lubricates bearing surfaces inside the supercharger, minimizing metal-to-metal contact and wear during high-speed rotor operation. By resisting thermal breakdown and oxidation, it preserves lubricant properties longer under heat and pressure, which helps maintain efficiency and component life.

• Reduces friction on bearings and shafts
• Provides thermal and oxidation stability under boost
• Helps maintain consistent rotor clearances and performance

How is ACDelco 10-4041 different from regular engine oil?

Supercharger oils are formulated for high-speed, concentrated bearing environments and often include additives tailored to shear resistance and low wear. Unlike general-purpose engine oils, this product targets the specific demands of supercharger internals, including rapid rotor speeds and localized heat.

• Synthetic base for stable viscosity at high RPMs
• Special additives for low wear and oxidation resistance
• Packaged in a 4 oz size for precise application and minimal waste

How do I use the 4 oz bottle during maintenance?

The small bottle is ideal for topping off the supercharger reservoir or performing a complete fill for applications that require a limited volume. Follow your vehicle or supercharger manufacturer’s fill procedures and capacities; some systems accept a single 4 oz bottle while others may require multiple bottles or a larger service container.

• Check manufacturer fill capacity and fill point location first
• Use a funnel or applicator to avoid spills and contamination
• Dispose of or recycle empty bottles according to local rules

Is this oil compatible with all supercharged vehicles?

ACDelco 10-4041 is formulated for use with a wide range of supercharged applications and meets GM OE specifications, making it suitable for many factory and aftermarket systems. However, always confirm compatibility with your supercharger maker’s recommendations and note that the product may be restricted in certain jurisdictions.

• Meets GM Original Equipment specifications
• Designed for both factory and many aftermarket superchargers
• Not for sale in California and certain OTC states—check local availability

Who is this for: This 4 oz ACDelco supercharger oil is aimed at professional technicians, DIY enthusiasts, and vehicle owners who need a precise, OE-spec lubricant for supercharger service, topping off between major services, or when following manufacturer-recommended maintenance. It’s particularly useful for owners of GM supercharged vehicles and anyone seeking a compact, synthetic formula that emphasizes oxidation resistance and low wear for high-speed supercharger components.
