I’m very happy with the smoother drive, noticeable results. Protecting my differentials and transfer case, I’m confident this product will keep my 4Runner on the road longer. ### ⭐⭐⭐⭐⭐ Best diff fluid EVER *by on Reviewed in the United States 25 May 2026* A true synthetic oil - for my 2005 Subaru Forester diff, front and rear, this is the only real choice.It's expensive yes, but I've 400K on mine and ZERO problems, I used this almost exclusively and don't regret it, I had it done once at one of those drive through quick change places and they put some crap in it, it didn't drive the same and i re-did it myself 1 oil change after using this.It's just hard to find in stock at the usual places, so i tend to buy a gallon and hold onto it for a whiles. ### ⭐⭐⭐⭐⭐ Great oil, great price! *by on Reviewed in the United States 23 March 2026* Great value for what I hope is quality oil. Changed out the rear differential and front differential on my Tundra yesterday and this new honey went into my old honey!😉Should give me another 50,000 worry free miles. Get the hand pump recommended so you don’t drive yourself mad! ## Frequently Bought Together - Red Line 57905 75W90 GL-5 Synthetic Gear Oil for Hypoid Limited Slip Differentials - 1 Gallon - Slippery Pete Fluid Pump for Gallon Bottles and Wide Mouth Quart Bottles (Not for Standard Quart Bottles) - Transfer Gear Oil, Transmission and Differential Fluid, Antifreeze with This 30cc Hand Pump - Red Line 50305 MT-90 75W-90 GL-4 Manual Transmission and Transaxle Lubricant (MTL) - 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.co.za/products/59080792-red-line-75w90-gear-oil-us-gallon-3-785-litres](https://www.desertcart.co.za/products/59080792-red-line-75w90-gear-oil-us-gallon-3-785-litres) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-28*
