## 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.
