It meets stringent MIL-PRF-81322 and NATO G-395 specs, offering superior low-temp pumpability, high-temp stability, water resistance, and excellent load-carrying capacity—trusted globally for over 30 years in military and aerospace applications. ## Description Mobilgrease 28 is a supreme performance, wide-temperature, antiwear grease designed to combine the unique features of a polyalphaolefin (PAO) synthetic base fluid with an organo-clay (non-soap) thickener. Its consistency is between an NLGI No. 1 and No. 2 grease. It offers outstanding performance over a wide temperature range. The wax-free nature of the synthetic base fluid, together with its high viscosity index compared to mineral oils, provide excellent low temperature pumpability, very low starting and running torque, and can help reduce operating temperatures in the load zone of rolling element bearings. The clay thickener gives Mobilgrease 28 a high dropping point value of around 300ºC, which provides excellent stability at high temperatures. Mobil grease 28 resists water washing, provides superior load-carrying ability, reduces frictional drag, and prevents excessive wear. Tests show that Mobil grease 28 lubricates effectively rolling element bearings under conditions of high speeds and temperatures. Mobilgrease 28 has also shown excellent ability to lubricate heavily loaded sliding mechanisms, such as wing flap screw jacks. For more than 30 years, Mobilgrease 28 has been the multi-purpose grease of choice for military and related aviation applications, worldwide. Mobil - Mobilgrease 28 Aviation Grease Features and Benefits: A particular requirement of aviation greases is the need to resist high temperature stresses, while providing excellent starting and low torque at low-temperature. To meet this combination of needs ExxonMobil product formulation scientists chose synthetic hydrocarbon base oils for Mobilgrease 28 because of their low volatility, exceptional thermal/oxidative resistance, and superb low-temperature capability. Formulators chose specific thickener chemistry and a proprietary additive combination which helps maximize the benefits of the synthetic base oils. ## Features - MIL-PRF-81322G - DOD-G-24508A, Amendment 4 - NATO G-395 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G3BTV5A | | Best Sellers Rank | #72,592 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #363 in Industrial Lubricants | | Brand Name | Mobil | | Container Type | Tube | | Customer Reviews | 4.8 4.8 out of 5 stars (281) | | Flash Point | 300 Degrees Celsius | | Global Trade Identification Number | 00071924459427, 00071924459588 | | Item Form | Grease | | Item Weight | 14.7 Ounces | | Liquid Volume | 405 Milliliters | | Manufacturer | Mobil | | Material | Synthetic | | Model Number | ASG-6-14OZ | | Number of Items | 1 | | Part Number | 970934 | | Recommended Uses For Product | Grease | | SAE J300 Viscosity Grade | 0W-50 | | UPC | 071924459588 071924459427 | | Unit Count | 13.7 Ounce | | Upper Temperature Rating | 300 Degrees Celsius | ## Product Details - **Brand:** Mobil - **Item Weight:** 14.7 Ounces - **Liquid Volume:** 405 Milliliters - **Material:** Synthetic - **Package Information:** Tube ## Images ![Mobilgrease 28 Aviation Grease , 13.7oz, MIL-PRF-81322 - Image 1](https://m.media-amazon.com/images/I/519oyB69CmL.jpg) ## Questions & Answers **Q: How is this applied?

We also sell this product in a 1/4oz kit which includes one 1/4 oz tin of Mobil 28, 1 pair of Black Latex Gloves, and 1 applicator brush. It is used on gun triggers specifically. **Q: Is it safe on rubber?** A: Yes, it is. It's a fully synthetic product. **Q: Can this be used in fishing reels?** A: Yes it can it is what I use for mine. **Q: Hi ,this grease can be used to lubricate the polyurethane bush of the leaf spring??** A: You can, but a general purpose, lithium complex NLGI #2 grease would be a better option for that application. ## Frequently Bought Together - Mobil - Mobilgrease 28 Aviation Grease , 13.7oz, MIL-PRF-81322 - 10ml 12ml Easy Glide Curved Tip Sterile Syringes - No Needle - 5 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/19749388-mobilgrease-28-aviation-grease-13-7oz-mil-prf-81322](https://www.desertcart.us/products/19749388-mobilgrease-28-aviation-grease-13-7oz-mil-prf-81322) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-17*
