That depends. You can get red and green oat and glycol based coolants. The colour is irrelevant (there are oranges and blues as well as it is only a dye), it is the specks that count. You could mix different coloured same spec oat and oat coolants toagether and different colour same spec glycol and glycol products together.However you would never want to mix oat and glycol products as they can counteract each other and cause corrosion. Why would you want to anyway. In an emergency situation I would use water rather than mix and then flush and change at the earliest opportunity.
They system will take it for a while but if you have mixed oat and glycol I pity the new owners if they dont pick this up and flush it, maybe not now but down the track. And they may have some comeback on you as well for mixing blatently incompatable products as stated on the directions.
