Ok antifreeze u got ripped off by about $11, also make sure the coolant is the same color that is in the car, i had an issue with some sevice techs putting the wrong colot in, "everything will be fine he says" 4 month in my coolant is brown to black color.

There should be no problem mixing the two colors provided they are pre-mixed as required. The blue can just be added straight because it is pre-mixed. The green should only be added straight in small quantities when a slightly heavier mix is required for colder temps. Otherwise, the green should be pre-mixed with distilled water to the appropriate concentration. Once the green is mixed properly, it can be combined with the blue without issue. Nissan just says mixing the two colors reduces the life to that of the green coolant :twocents:

My guess is that idiot tech poured a large quantity of straight green coolant in your car to get that kind of result but who knows :wtf2:

Let's be clear, the coolant is not labeled lifelong. Nissan is not suggesting that you don't ever need to change your coolant. The term they use is Long Life. There is a difference. Typically, coolants are good for about 150K miles or 5 years.

The Nissan green coolant is concentrate (must add distilled water) and rated for 105K miles or 7 years. The Nissan blue coolant is pre-diluted (50/50 mix) and rated for 135K miles or 10 years.

10yrs? cool i guess i DONT have to do the coolant drain/fill afterall! :D
one less thing i need to do in 2016. :tup:
