Why You Should Use Honda Coolant Only...

[Racing Rice]

In order for companies such as Prestone to make a coolant like Honda they have to pay Engineers to research and develope something that chances are they probably wont sell all that much of anyhow. Like BDC said most people go buy the cheap stuff because they could careless what goes into their cars. The fact of the matter is its probably not cost effective for a company like Prestone to do all the R&D and the machinary and whatever else you will need to make something like that, just to pick up a few more customers. Though its hard to say how much sales would improve without knowing all the details, I just dont see it being that big of a margin.
