Coolant FL22

I just did the Coolant change for the first time. Used a gallon from a mazda dealer.

The reserve tank is low after using the entire 1 gal. Is there a way I can buy a smaller amount?

If I ended up buying another then it will be for another 5 yrs or so - storage space is also another issue!

Can I use this to top it off - Zerex 1 Gallon Green 50/50 Coolant/Antifreeze - it’s 5yr service - so I went with dealer part - but ...

Update - did some research
0000-77-508E-20 - premix - $25
0000-77-501E-02 - concentrate - $30 - Had I known, I might have gotten this. Now I need to find one + distilled water!

If you're going to end up with some on the shelf anyway I'd buy the concentrate. You can mix the correct ratio and still have the same size container.

Add distilled water or better yet, de-ionized water to top off. No need to have anything left on the shelf.

1 overflow tank of water is not going to change the percentage enough to say so.
