I have the green coolant in my car, and before that it had green coolant....then it sat for a number of years with green coolant....no idea when it first received green coolant but so far I have had no issues.....but I feel like in need to drain it out asap as I might end up getting a fine for running it in the car :p

No idea if it causes issues with head gaskets or not....
