Factory fill is good for 11 years or 132k Miles. Mixing your coolant reduces the life to I think 30K miles or 50k Miles, but I know it's reduced significantly.

I couldn't find the part in the owner's manual that says mixing coolants reduces life, but I do believe you that mixing certain coolants will decrease coolant performance/life, and can even solidify and clog up the system when mixing the wrong chemicals. However, the coolant I mixed with the factory coolant is ethylene-glycol based and silicon free, so hopefully nothing catastrophic will happen.
I'll flush the coolant earlier than normal to be on the safe side. Next time I'll wait until I can get my hands on the OEM coolant before adding any.
