Review: Always a great product with Lucas Oil - Great gear oil, have used it in both my 2017 Ford F-150 and my 2017 Ram 2500 front and rear differentials. It seems to work great, it has been in my F-150 for almost 2 years and I haven’t heard any noises, so I ordered more and used it in my Ram, so far I e only put about 600 miles on it but haven’t heard any noises and haven’t noticed any issues with it. Lucas Oil is always a great product have been using it since I was a teenager in different things. ATV’s, trucks, brush hogs, lawnmowers, anything I’ve owned that requires gear oil. Review: Good deal. - Top tier gear oil cheaper than the auto parts store, whats not to like? ## Features - Heavy duty - High performance - Stands up to high temperatures ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000IG20RC | | Best Sellers Rank | #18,732 in Automotive ( See Top 100 in Automotive ) #40 in Gear Oils | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Container Type | Bottle | | Customer Reviews | 4.9 out of 5 stars 1,454 Reviews | | Global Trade Identification Number | 00049807100483 | | Included Components | 1x 1 Gallon Bottle | | Item Form | Oil | | Item Type Name | gear oil | | Item Weight | 7.6 pounds | | Liquid Volume | 3.8 liters | | Manufacturer | Lucas Oil | | Material | Blend | | Model Number | LUC10048 | | Number of Items | 1 | | Number of Packs | 1 | | Package Information | Bottle | | Part Interchange Info | 10048 | | Part Number | LUCA10048 | | Recommended Uses For Product | Vehicle | | SAE J300 Viscosity Grade | 75W-90 | | Specific Uses For Product | Vehicle | | UPC | 049807100483 | | Unit Count | 128 Fluid Ounces | | Upper Temperature Rating | 1 Kelvin | | Viscosity | 75W90 | ## Product Details - **Brand:** Lucas Oil - **Item Weight:** 7.6 pounds - **Liquid Volume:** 3.8 liters - **Material:** Blend - **Package Information:** Bottle ## Images ![10048 Synthetic SAE 75W-90 Gear Oil - 1 Gallon - Image 1](https://m.media-amazon.com/images/I/71VmBL00mxL.jpg) ## Questions & Answers **Q: Is it GL4 or GL5 spec oil?** A: Gl5See https://www.lucasoil.com/images/medialibrary/TDS10047_Syn-75W-90-GearOil.pdf **Q: Is this g4 or g5 gear oil i need g4 for older transmission?** A: The year really does not matter except to look up what type of oil is needed, if it calls for ATF, then gear oil will not work, if it calls for 90W gear oil, then the 75-90W will work, some times in hot or extreme you will need 140W, look in your glove box manual for type needed or look online, I run this lucas in my motorcycle final drive and transmission, hope this helps...or call Orileys and ask **Q: will this work in a 2010 silverado with limited slip or do ya need the limited slip additive?** A: My old Dana 60 limited slip needed the additive when using this Lucas synthetic gear oil regardless I what It says on the bottle I'm sure it's fine in a mechanical locking differential but my experience using in my old limited slip required some Kendall additive **Q: Can I use Lucas 70-140 synthetic gear oil in 2006 f350 rear differential with no limited slip Additive?** A: 70 -140 is for heavy duty applications. I use it on my 2500 ram Cummins with a Dana 80 rear dif and a Dana 70 open front diff. Factory provided limited slip rear differentials suck. I quit depending on my limited slip Diff within the first year I had my 99 Diesel Ram therefore, I quit depending on additives. If your limited slip is still works, use the additive recommended by the dealer. I might not help, but it will not hurt. Better yet, swap it out for a Detroit Locker, or something milder if the Detroit Locker is too much for you. If you use your F 350 mostly for towing, you may want to go for a Tru-Trac or something else with gears, no clutches. There are also electric and air activated locking differentials that work great in towing applications since they allow you to decide when to, or when not to lock your rear end. But they all will cost you a left arm and a right testicle. Hope this helps. Good luck! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Always a great product with Lucas Oil *by S***S on August 3, 2026* Great gear oil, have used it in both my 2017 Ford F-150 and my 2017 Ram 2500 front and rear differentials.

Why buy a quart if you can buy a gallon. I know I will use it all and it's a high quality product. I find im more Lilly to do the maintenance if I already have the supplies. This is enough to do my rear differential twice and seeing how I do it every 20k miles I can live with that. It always comes out looking good which tells me it's doing it's job. ## Frequently Bought Together - Lucas Oil 10048 Synthetic SAE 75W-90 Gear Oil - 1 Gallon - Lucas Oil 10047 SAE 75W-90 Synthetic Gear Oil/Transmission and Differential Lube - 1 Quart - Lucas Oil 10122 Synthetic SAE 75W-140 Gear Oil - 1 Gallon --- ## 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.jp/products/6632724-10048-synthetic-sae-75w-90-gear-oil-1-gallon](https://www.desertcart.jp/products/6632724-10048-synthetic-sae-75w-90-gear-oil-1-gallon) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-25*
