Call me crazy, but I bought a 5 litre container of double protect ultra. Could someone tell me what the shelf life of the product is, if not opened, and after opening? I can't fjnd the information anywhere on any site.
Thanks
I also bought a bucket of 5L coolant,I have an AMS system,About half of the capacity is left after filling,If the coolant is replaced once a year,Should be used up before expiration,
