Nissan Green Vs Blue Coolant – Which Is Better?

So, its time to change the coolant in your Nissan, but which coolant do you use? There are a couple of different colours and several different variations of Nissan coolant In this article we hope to answer which one you should use in your car. Carry on reading below.

The Origins of Nissan Blue Coolant

In 2009 Infiniti (Nissan’s luxury brand) began filling some of its vehicles from the factory with Nissan Long Life Antifreeze/Coolant (LLC) that is blue in colour.

Infiniti then began to transition all their vehicles to Blue coolant with this transition being completed in 2011.

Blue Coolant

Nissan’s Blue coolant is the company’s long-life coolant (LLC) and is designed to provide a much longer service interval. According to Nissan the coolant should last 10 years or 220,000 km (135,000 miles) from the factory, however some other sources state that the first change should be around 7 years or 170,000 km (105,000 miles). Future coolant changes with Nissan Blue should be every 5 years or 120,000 km (75,000 miles).

Below we have listed the two different versions of Nissan Blue that are available for purchase:

999MP-L25500P (Pre-mix)This is the part number for the blue coolant found in newer Nissan and Infiniti vehicles. This coolant is pre-mixed, so there is no need to add water.

999MP-L255QTP (Concentrate, but beware) – Interestingly, Nissan calls this coolant a concentrate but states that you should not add water. The packaging of this coolant also states that it is only intended for top up usage for lowering the freezing temperature protection and that it is for “dealer use only”. It is a good idea to avoid this coolant and go for the pre-mixed solution above.

Green Coolant

Nissan Green Coolant has a shorter service interval than Nissan Blue with changes needed every 4 years or 96,000 km (60,000 miles).

999MP-AF000P (Concentrate)This is the part number for Nissan Green coolant and it comes in concentrated form. This means that it needs to be mixed with distilled water in a 50/50 ratio before use.

Can Either Coolant Be Used in my Nissan?

Yes, either coolant be used in your Nissan or Infiniti vehicle.

Can the Two Coolants Be Mixed?

Yes, Nissan Green and Blue coolants can be mixed together (just remember to dilute Green first before use in a 50/50 ratio). If you do mix the coolants, the mixture will have the life of the Green coolant (4 years or 96,000 km/60,000 miles).

Which is Best, Green or Blue Coolant?

Both coolants will work equally as well in your Nissan, so in terms of a performance benefit there really isn’t a difference. We personally would probably use Nissan Green as it comes in concentrated form (makes it a bit cheaper) and feel that changing the coolant more regularly is better for preventative maintenance.

For both coolants we would personally change them a little bit before the recommended service intervals just to be on the safe side.
