Hmm... that's a good question about topping off with other brands of OAT coolants with different colors. If it was me, I'd put on my shoes and get oem. I wouldn't want to question the cooling system doing it's job over driving 30 mins away to get the right stuff.
I had my share of cooling issues to know that I would rather spend the extra time to do it correctly vs costing me in the long run.
