DIY Guy ..........Thanks for sharing this informative article!An article that I read several months ago that I found to be a very good example as to why.
And I'm sure all those colored fluids have different chemical inhibitors. They are just colored to make it easier to discern, not to sell more branded fluids. Ethylene glycol based or not, I wouldn't dump the green stuff in with my orange stuff.Best is to compare ingredients in the msds reports for each product. No difference in Honda, Peak, Prestone, etc. They are all ethylene glycol based coolants, with same basic ingredients. The color is changed to sell more 'branded' fluid. Coolant should be changed every three years to prevent galvanic corossion.
The only Honda brand fluids you should stick to using are for your transmission, differential, and power steering.
