As for using Prestone anti-freeze, I wouldn't. Prestone has changed it's formula to that of GM's Dexcool, which is the absolute worst stuff you can run in an engine. Even the GM guys are getting rid of it, as it clogs heater cores and engine blocks. It forms a crystal like substance, and just keeps getting worse the longer it's in place. I don't know about the blue Honda stuff, but it wouldn't surprise if it did it too. I've been using Peak in everything for the last 10 years or so without any problems in my GM's, and 4 years now in my Hondas.
I've been using Prestone coolant since I've owned my Accord, so 10.5yrs now. At first I didn't know any better, and then I came across threads and threads of coolant stuff. I remember several posts stating that the important thing be that the coolant be silicate free. I was ready to go to Honda blue coolant, but then I read the Prestone label and it stated it was silicate free.
I've never had a problem with the coolant or the coolant system outside of dumb issues like hoses getting old and developing leaks or the radiator itself breaking for something funny AF.....like "swallowing" a pigeon.....
Anyway, that's a whole different issue / topic. I was just curious about the PS fluid thing and used the coolant as a comparison.
