I use OAT coolant in my Zx14r and it seems to run about 5c cooler. OAT also has a life of 6 years (not that I leave it in that long)
Organic Acid Technology
Does anyone use it in their s10? I’d like to if it’s ok. Can’t think why it wouldn’t be.

The fact that it is organic does not mean that it does not degrade over time. Two types of degradation: 1) from acids (organic or inorganic), which protect you from corrosion, 2) from glycols, which protect you from boiling / freezing. If the label says "refrigerant" does not mean that it will work "colder", it means that in the correct proportion, the liquid will boil above 100 C. What manufacturers recommend is to regularly measure the levels of acid / glycols in the liquid, and here is where there is a difference between organic and inorganic products and it is that organic manufacturers also offer you in a small container the additives to replace them depending on the samples, without the need to change all the cooling liquid. Generally that small container only with acids and glycoles, you don't find it anywhere. Another problem that usually exists, is that each manufacturer uses different types of organic acids, and the test strips are different for each manufacturer, so if you measure the level of acid and who measures it, it does not have the test strips of the brand of liquid, probably wrong measurements. In conclusion, any refrigerant / antifreeze, of recognized brand, organic / inorganic, in the correct proportion and being the pressurized circuit, are doing well. You just have to change it regularly: inorganic (1-2 years), organic (2-3years). And as I said before, that different factories use different acids, if you have to refill, it should always be done with the same product (which are the same color, does not mean that it is the same). If it is filled with another brand, which contains other acids, the anticorrosive properties are diluted, not the refrigerants / antifreeze
And all the more important to achieve 100% effectiveness of the anticorrosive properties is the "water" you use for the mixture (completely demineralized / deionized). If you use a premixed product, "water is supposed to be correct"
salts, not only attack iron, wreak havoc on aluminum as well. Only in aluminum, you don't notice it in the water, you see it when you disassemble the engine
6 years, it is likely to be so, but you should regularly measure acid / glycol levels, or change it before so as not to risk
