The NAPA by me has the concentrate in stock. The coolant belongs to the Hybrid Organic Acid Technology (HOAT) category. Pentofrost A3 is our first alternative to Subaru Super Coolant, which is a phosphate OAT, i.e. I am leaning toward going with the Peak Global. In this article, we will discuss in detail some of the alternatives of Subaru Super Coolant. They only do what is called a forced drain and fill. None of the Subaru dealers in my area even do the flush. Subaru specifies a non-silicate, non-phosphate and non-amine antifreeze. Now that youve drained it, you dont have to replace it with the same thing unless you want the extended drain protection back. I am going to do the flush and change myself, I just asked the dealer service about switching to the blue since I was there for the recall. Subaru Super Coolant is blue in color, and designed for a usable life of 11yrs/137.5k miles (if not diluted in any way). I doubt though that you would find a Subaru dealer to do it using PGL, but you could ask. I also think Peak Global Lifetime would be a good choice especially if you find the concentrate to use with a complete flush. Look no further than NAPA Gold for all your filtration needs.

'If' true that would also make it unique as compared to Honda and Toyota both of which newer PHOAT AFs are compatible with or can be used in place of the shorter interval PHOAT previously used. No idea other than the fact that it came with the shorter interval green PHOAT and he's afraid to recommend anything other than what it came with.

Would anyone here know why they would recommend against that?

When I asked, the dealer did not recommend switching the car to the blue Subaru extended life coolant.
