The manufacture has just changed the color of the bottle after decades of it being orange. It is a little of putting after being so used to the orange bottle. We are unsure at the moment if this has been caused by a shortage of bottles in the supply chain or if it is here to stay. But be assured it is the same product from the manufacture. Same part number and still the best oil to use available. **Q: Mil spec?** A: Yes an exact fit ## Frequently Bought Together - SeaStar Solutions HA5430H SeaStar/BayStar Hydraulic Steering Fluid, 1 Quart - Mogankey Boat Bleed Kit Filler Kit Compatible with Inboard/Outboard Seastar Hydraulic Steering Systems Replace Oil Filler Hose Bridge Tube Kit Boat Bleeder Hose Quick Connect Bleed Kit - HC5345 Seal Kit For SeaStar Hydraulic Steering Cylinder Seal Kit with Pin Wrench HS5157 compatible with HC5340, HC5341, HC5342, HC5343, HC5344, HC5345,HC6750, HC6751 --- ## 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.gr/products/152445766-seastar-solutions-ha5430h-seastar-baystar-hydraulic-steering-fluid-1-quart](https://www.desertcart.gr/products/152445766-seastar-solutions-ha5430h-seastar-baystar-hydraulic-steering-fluid-1-quart) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-02*
