The shipment I received appeared to be genuine, equivalent to Subaru ATF-HP. If it was counterfeit, they did an extremely good job copying the bottle and the label; and what would they have put in the bottle that would have been significantly cheaper than ATF-HP but not as good? Bottom line, I don't know how you would tell if the product you received was counterfeit. **Q: What color is good on the stick after 150,000?** A: New, out of the bottle fluid is red. If you haven't changed it in 150,000 miles I would bet it is dark brown and more viscous. Red is best. For a quick solution, with the motor off you can siphon most of the fluid out of the holding tank and replace it with this fluid. After a week you can do it again and you should be good. **Q: Is this good for 2008 Subaru Outback automatic transaxle (2.5i 4-cylinder engine)?** A: This is the fluid that Subaru specifies. See page 11-24 of your owners manual for more information on recommended fluids and capacity for your automatic transmission. I use this ATF in my 2008 Subaru Outback 2.5i. **Q: Anyone know if I can put Idemitsu hp in my 05 3.0 outback that already has subaru hp fluid in it? I've been told yes, just need to add a qt or 2** A: My understanding is yes. ## Frequently Bought Together - Idemitsu ATF Type HP Automatic Transmission Fluid for Subaru - 1QT, Red, (30040099-75000C020) - Subaru Genuine Super Coolant Blue Prediluted SOA868V9272 1 Gallon Pre Mixed 50/50 2009 and Newer Ascent BRZ Crosstrek Forester Impreza Legacy Outback WRX - Subaru SOA868V9220 Brake Fluid - 12 fl.oz --- ## 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.uk/products/271969366-idemitsu-atf-type-hp-transmission-fluid-for-subaru-1-quart](https://www.desertcart.co.uk/products/271969366-idemitsu-atf-type-hp-transmission-fluid-for-subaru-1-quart) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-08-17*
