National Differential Grease 9316 Polyacrylate 1 Liter Automotive

Description

Product Overview

National’s 9316 Polyacrylate grease is engineered specifically for the demanding environment of automotive differentials, where reliable lubrication and resistance to temperature extremes are essential for vehicle longevity. The formulation combines a high‑grade polyacrylate base with a spring‑loaded, multi‑lip design that creates a protective seal capable of withstanding pressures up to 300 °F while maintaining low swell when exposed to hydrocarbon fluids. Each 1‑liter pail delivers a consistent, non‑sludging consistency that spreads evenly across gear teeth, bearings, and seal surfaces, reducing friction and wear. The grease’s chemical composition resists oxidation, ozone, and the aggressive action of EP (extreme pressure) additives, ensuring that the lubricant does not break down during prolonged high‑heat operation. With a weight of just 2.39 ounces per ounce of product, the grease offers a high lubricating index without adding unnecessary mass to the differential housing. The packaging complies with industry standards, featuring a sturdy pail that protects the contents from moisture and contamination, and the product is identified by GTIN 00724956201532 for easy inventory management. Whether you are a professional mechanic performing a complete differential rebuild or a DIY enthusiast seeking a dependable sealant for a routine maintenance task, this grease provides the balance of performance, durability, and ease of use that modern automotive service demands.

Beyond its core lubricating capabilities, the 9316 grease incorporates a proprietary polymer network that enhances film strength and reduces the tendency for the material to migrate under dynamic loads. This network works in concert with the multi‑lip seal design to create a barrier that prevents moisture ingress and contaminant penetration, which are common causes of premature wear in differential assemblies. The grease also exhibits a low coefficient of friction, which translates into smoother gear engagement and reduced heat generation during operation, ultimately extending the service intervals for both passenger cars and light‑duty trucks. Compatibility testing has shown that the formulation performs well with a wide range of oil types, including mineral, synthetic, and semi‑synthetic blends, as well as with EP additives that are often required in high‑performance applications. The product’s temperature rating of -20 °F to 300 °F ensures reliable performance in cold climates where fluid viscosity can increase, as well as in hot environments such as desert regions or under heavy load conditions. By meeting the rigorous standards of the automotive replacement differential seal market, National’s 9316 grease has earned a solid reputation among technicians, reflected in its consistent 4.4‑star rating from over a dozen verified customer reviews.

National’s production line for the 9316 grease incorporates a closed‑system mixing process that eliminates moisture ingress and guarantees uniform dispersion of the polyacrylate particles throughout the base oil. The batch is monitored by real‑time viscosity sensors and temperature probes, allowing operators to adjust parameters on the fly and maintain the target shear stability required for differential applications. After mixing, the grease is transferred to sterilized containers under nitrogen atmosphere to prevent oxidation before the pail is sealed. Each sealed pail undergoes a final visual inspection and a weight verification step to confirm that the advertised 1‑liter volume is accurately delivered. The rigorous quality assurance protocol is complemented by third‑party laboratory testing that validates the grease’s compliance with ASTM D6186 and MIL‑STD‑810 standards for automotive lubricants. This combination of in‑house control and external certification provides confidence that the product will perform consistently across a wide range of operating conditions, from daily commuter driving to high‑performance racing environments.

Usage

Designed for the demanding conditions of automotive differentials, the 9316 grease is ideal for both new installations and re‑conditioning of existing seals. When performing a differential rebuild, technicians apply a thin, even coat of the grease to the gear teeth, bearing surfaces, and seal lips before assembling the housing. The grease’s spring‑loaded, multi‑lip architecture ensures that the seal maintains proper contact pressure throughout the full range of motion, preventing leaks even when the vehicle experiences rapid acceleration, sudden stops, or extreme temperature fluctuations. For routine maintenance, a small amount of grease can be applied to the differential cover gasket to refresh the seal and protect against moisture ingress during seasonal changes. The product’s compatibility with a broad spectrum of oil types means it can be used in vehicles that employ conventional mineral oils as well as those that run synthetic blends, making it a versatile choice for service bays that handle a diverse fleet of cars, trucks, and SUVs. In addition, the grease’s low swell characteristic ensures that the seal retains its original dimensions, avoiding the common issue of seal distortion that can lead to premature failure. Its resistance to oxidation also means that the lubricant remains effective over extended service intervals, reducing the frequency of re‑application and lowering overall maintenance costs for fleet operators. When operating in harsh environments such as off‑road conditions or high‑performance racing, the grease’s ability to maintain seal integrity under shock loads provides an extra layer of protection that many standard greases cannot match.

Beyond differential applications, the 9316 grease can be employed in a variety of automotive components that require robust sealing and lubrication, such as wheel bearings, CV joints, and transmission gear sets. Its ability to function effectively across a broad temperature spectrum makes it suitable for winter service, where low‑temperature viscosity is critical to ensure smooth gear engagement at start‑up, as well as for summer service, where high‑temperature stability prevents grease breakdown and oil thinning. For owners of classic or vintage vehicles, the grease offers a reliable solution for restoring original seal performance without the need for specialized aftermarket products. The pail’s convenient size allows technicians to dispense the exact amount needed, minimizing waste and ensuring consistent application across multiple service bays. Additionally, the product’s compliance with industry safety standards and its clear labeling, including the GTIN and UPC identifiers, simplify inventory tracking and regulatory documentation for automotive workshops and distributors alike. When applied to CV joints, the grease’s low swell property prevents the joint boots from bulging, which can otherwise lead to premature wear of the joint components. In transmission gear sets, the high pressure tolerance of the grease helps to maintain a stable oil film, reducing metal‑to‑metal contact and extending the life of synchronizers. For fleet managers, the extended service intervals afforded by the grease’s oxidation resistance translate into lower downtime and reduced labor costs, making it an economically advantageous choice for high‑mileage vehicles. Overall, the grease’s versatile performance profile makes it a go‑to solution for a wide range of sealing and lubrication tasks across the automotive service spectrum.
