Honda/Acura recommends low/no silicate and phosphate coolants. The silicate may eventually cause damage to our alumninum blocks and is the reason that Honda went to the low silicate formula. Don't caught up with the whole color issue. There are silicate and non-silicate formulas that are green color. For example the OEM coolant is non silicate and is green color.

If I were you I would either use OEM fluid or Zerex's G-05 coolant. The G-05 is a low silicate/phosphate formula that is reasonably priced. Something to note though is that the G-05 coolant is yellow in color.
