The last time I looked at Prestone it does have silicates in it which is an
abrasive. I have read from more than a few people that claim Prestone is
not the choice to use in our Honda cars and for a few dollars it isn't worth
the effort to challenge it. I am sure Honda sells a reasonably priced
antifreeze. You only need a gallon of it anyway I believe.
