Trusted by military and commercial aviation for over 30 years, it delivers exceptional load-carrying ability and stability, making it ideal for high-speed rolling bearings and heavily loaded sliding mechanisms. ## 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. Review: Awesome - Very good deal for the price. I use this on bearings for an industrial dust collector that sits outside in the weather all year long. I've heard some guys use this as a replacement for isoflex grease in crank bearings. I haven't tried that yet but it would probably work. Very high quality product. Review: Top military/commercial grade grease recommended by an engineer who has put it to the test - I got it for here at home to do my garage door (runners, chain, etc.) and then put a dab on my car's sunroof and the drawers on my old roll-away chest. Everything is working better now and smoothly sliding quietly. The garage door went from squealing to quiet and is as smooth as glass. I chose this grease since it's what I worked with when I worked on aircraft actuators (commercial and military) as an engineer. I've personally tested this grease to military standards from -65F to 350F and it works flawlessly in that range. At -65F, I cold soaked my test article for 4 hours. When I applied power, it broke away without a hitch and started moving as required, even when I had added a ton of water to the test setup, this grease still broke free and moved smoothly. Performance at high temperature was never in doubt, it worked perfect. That's why this is used. If you've ever flown in a plane, you very likely had Mobil 28 in use all over the plane. The other one we saw use of is Aeroshell 7, but Mobil 28 was our more common. It's well regarded for staying where you put it. It migrates with moving parts as it should, but it doesn't splatter or drizzle off, etc. Can't recommend this grease enough. My parts are flying with it on military aircraft, so it should be fine for your regular uses. ## Features - Brand: Mobil - Liquid volume: 13.7 fluid ounces - Container Type: Pail - Item form: Grease - Material: Synthetic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G3BTV5A | | Best Sellers Rank | #25,398 in Automotive ( See Top 100 in Automotive ) #6 in Heavy Duty Vehicle Greases & Lubricants | | Brand | Mobil | | Brand Name | Mobil | | Container Type | Pail | | Customer Reviews | 4.8 out of 5 stars 248 Reviews | | Flash Point | 300 Degrees Celsius | | Global Trade Identification Number | 00071924459427, 00071924459588 | | Item Form | Grease | | Item Weight | 14.7 Ounces | | Item weight | 14.7 Ounces | | Liquid Volume | 405 Milliliters | | Liquid volume | 405 Milliliters | | Manufacturer | Mobil | | Material | Synthetic | | Model Number | ASG-6-14OZ | | Number of Items | 1 | | Number of Packs | 1 | | Package information | Pail | | Part Number | 970934 | | Recommended Uses For Product | Aviation, High-performance machinery | | Recommended uses for product | Aviation, High-performance machinery | | Specific Uses For Product | Prevent Corrosion | | 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:** Pail ## 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? I understood it came in a 16oz can, is that correct?** A: Mobil 28 is a grease. This particular picture is the 14 oz tube and is applied by using a grease gun. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome *by K***. on 15 December 2025* Very good deal for the price.

I did this at around 1000 miles and my ebike is now at 3500 miles with no motor issues, so seems to be doing its job. When replacing the grease, just wipe off as much of the factory grease as you can, then pack is much of this into the gears as you can, like you would when packing a wheel bearing. I still have a bunch of it left and it's good quality, so I'll probably use it for my car and other tools that need grease. ## 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.tn/products/377605035-mobilgrease-28-aviation-grease-13-7oz-mil-prf-81322](https://www.desertcart.tn/products/377605035-mobilgrease-28-aviation-grease-13-7oz-mil-prf-81322) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-21*
