I won't leave any fluid in my truck for that long, but it is good that the coolant is good for that long. This is the coolant used in the OTR trucks, and comes highly recommended by Navistar!! Use what you want, but you need to keep your SCA level where it belongs.
When the Gold was introduced it was said to be maintenance free. Ford saved tons of cash by going to a universal coolant, that doesn't mean it is a proper coolant though for diesels. Don't believe me, do the test for yourself. Take 1 cup of gold coolant right from the jug and 1 cup of distilled water and test it. You will get 800ppm far below even the min protection level. The test strips don't lie. But use what you want, I like to use the best possible, but I am very anal about my truck!!
