Hi, it's a 2013 CX-9. Just found out that the engine coolant is low (on L mark). Went to an auto shop and pick up a gallon which is a "conventional green" that has: ethylene glycol, diethylene glycol denatonium benzoate, corrosion inhibitors defoamer and dye. Based on a char in the auto shop, all Mazda uses green color coolant. I am not totally savvy when it comes to car maintenance, so just want to get some feedback regarding if this is the right product to top off before I do it myself.
