Decent, but it's tough on the environment.

TL;DR The factory-fill coolant for 2009-and-newer Subaru models, meeting ASTM D3306 with a phosphate-free OAT inhibitor matched to Subaru's aluminum engine metallurgy. Ethylene glycol base with a WARNING signal word; the 2018 SDS classifies only H303 (may be harmful if swallowed) and H373 (organ damage via repeated exposure). Keep secured from pets and children.
This is Subaru of America's current OEM Super Coolant Blue (part SOA868V9272), sold pre-diluted 50/50 and ready to use without adding water. The inhibitor technology is P-OAT (phosphate-free organic acid technology), the correct chemistry for Subaru's aluminum-intensive cooling systems; using the wrong inhibitor package can cause corrosion in these engines. Service interval follows the owner's manual, consistent with extended-life OAT chemistry. Ethylene glycol base · not a propylene glycol alternative for households where pet safety is the priority.
Best for 2009-and-newer Subaru owners (Ascent, BRZ, Crosstrek, Forester, Impreza, Legacy, Outback, WRX) who want verified OEM-spec coolant without guessing on compatibility. The price premium buys certainty; community forums broadly confirm it's the correct OEM match. Skip if you need a concentrate or if pet safety drives you toward a propylene glycol alternative.
WARNING signal word; H303 (may be harmful if swallowed) and H373 (kidney damage via prolonged repeated exposure). Gloves and eye protection are indicated per SDS §8 during drain or pour work. The Prop 65 warning flags ethylene glycol as a reproductive toxicant via ingestion. Collect spent coolant and take it to an auto parts store recycling program.
Yes. Part number SOA868V9272 is Subaru of America's current factory-specified Super Coolant Blue for 2009 and newer models · Ascent, BRZ, Crosstrek, Forester, Impreza, Legacy, Outback, and WRX. It replaces the earlier SOA868V9270.
Yes. The Amazon listing feature bullets and SDS §15 confirm a bittering agent is present. This makes the coolant taste unpleasant to deter accidental ingestion by pets or children. The ethylene glycol base still carries a Prop 65 reproductive harm warning and an H303 (may be harmful if swallowed) classification · the bittering agent reduces palatability but does not eliminate the ingestion hazard.
Subaru specifies drain intervals per the owner's manual, which varies by model and year. The P-OAT (phosphate-free organic acid technology) inhibitor chemistry is consistent with extended-life OAT service intervals typical for Asian OEM specifications. Consult your specific owner's manual for the Subaru-recommended drain interval for your vehicle.
Subaru does not recommend mixing with non-OEM or different-chemistry coolants. The P-OAT inhibitor package is formulated specifically for Subaru's aluminum engine metallurgy. Mixing with IAT (green silicate) or incompatible OAT chemistries can degrade inhibitor effectiveness and risk corrosion of cooling system metals.
Ethylene glycol (CAS 107-21-1) is on the California Prop 65 list for reproductive toxicity via the ingestion pathway. The back label confirms this warning. This is standard for any ethylene glycol-based automotive coolant sold in California.
