Colorants are used in antifreeze fluids helps differentiate the chemistry in them.

Yes, you can go by color. The Subaru owners manual indicates the use of Glycol based antifreeze,

50/50 with soft water. There are no other indications in the engine compartment.

All 3 types of antifreeze fluids, produced by Valvoline under the Zerex brand, with or without silicates and phosphates are glycol based. One is green, a second one is orange (OAT technology) and the other one is clear (HOAT technology).

Since my car came with the green antifreeze from the factory, I will continue to use the Zerex I mentioned in my initial post, the same used by Nissan.

Hi,

'Tis funny! Wonder how many people caught it? :D

The ones in my '71 Jag were flushed once in '86. So far, so good.
