Mixing purple with existing green coolant that has additive?

[themechanicalford]

Bought the truck last year used and it has green coolant. Guy says that he had the Ford dealership do the coolant flush recently, (I assume they used the green coolant with the additive). I now need to add some coolant and I purchased the purple coolant. Am I okay to mix this new purple coolant with the existing green? I see a lot of conflicting info but nothing specifically about our trucks.

Should be fine. Purple is just green with SCA.

If it’s the oat stuff that mopar was running for a while it doesn’t mix with anything other then itself
