## Overview

Idemitsu ATF Type HP is a factory-fill quality automatic transmission fluid tailored for Subaru vehicles (pre-2005 models) with conventional transmissions. Engineered for precise frictional control, superior anti-wear protection, and long-lasting oxidation resistance, it ensures smooth shifting, extended transmission life, and prevents sludge buildup. Trusted by Asian import manufacturers, this 1-quart fluid offers excellent seal conditioning to minimize leaks and maintain optimal transmission performance.

## Description

IDEMITSU ATF Type - HPFormulated to meet the specific requirements of Subaru vehicles equipped with conventional (non-CVT) transmissions up to model year 2005Recommended for service-fill in all Subaru automatic transmissions where SUBARU ATF HP is specifiedFuel economy demands and more sophisticated electronic controls have made automatic transmissions not only more complex, but also unique to each vehicle manufacturer. Long gone are the days of having just a couple choices of automatic transmission fluid type. Idemitsu is the factory fill Automatic Transmission Fluid (ATF) supplier to most Asian imports. Idemitsu application-specific ATF products match the exact friction materials and performance requirements of each different vehicle model for which they are made.

Review: Idemitsu ATF Type HP - I used this fluid for a transmission service where the vehicle called for Type HP fluid. Shifting felt smooth afterward and I did not notice any leaks or issues. The fluid looked clean and poured easily. It is also significantly less expensive than buying OEM fluid directly from the dealer.
Review: I only use Subaru Transmission Fluid - The automatic transmission from Subaru works much better than off-brand fluid.

## Questions & Answers

**Q: How can i be sure this is the authentic idemitsu brand and not fake, and, this meets the specs for a 2011 subaru outback 3.6r?**
A: (I'm thinking the 3.6R got the old school 5EAT and not the newer CVT.)  

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.

### ⭐⭐⭐⭐⭐ I only use Subaru Transmission Fluid
*by A***R on 17 January 2026*

The automatic transmission from Subaru works much better than off-brand fluid.

### ⭐⭐⭐⭐⭐ Subaru OEM for Half the Price
*by L***E on 21 July 2019*

I'm not sure why Subaru feels that its necessary to rebrand something a double the price, but that's exactly what they do with this ATF. Ignore the Subaru branded stuff you get at the "stealership" and just buy this. Its literally the same stuff in a different bottle. Speaking to the fluid specifically, I try to cycle 4 quarts through my Forester every other oil change and paying Subaru's prices would make that borderline prohibitively expense. This stuff is fine to use (the owner's manual specifically mentions it) and it is identical to the OEM fluid. I've heard good things about the Valvoline brand synthetic fluid, but I'm paranoid about using something that Subaru doesn't specially recommend since their vehicles are kind of "picky" about things like that, and I've noticed improved shifting after every cycle of this ATF. Is it the best? Probably not, but it seems to be getting the job done, is covered by the manual, and isn't too expense. Would recommend.
