so I went to the dealer and bought a gallon of antifreeze for my 09 si with 40K miles cause I'm a little **** about maintenance.

anyways, last night I'm draining and filling and when I go to fill I notice the honda antifreeze is premixed 50/50.
Hmm, I hadnt noticed that before, and now was worried that I had enough.
When I do my toyota, the dealer sells their special read coolant (yeah, toyota does the scam too...must buy coolant from them, lol) and it is not premixed, so I guess I didnt bother looking.



I ended up adding probably another half gallon of water, although not sure as I didnt measure it out....

So, my question is do I need to do this all over and THIS time go buy two gallons of antifreeze?
Is my antifreeze diluted too much?

thoughts?

More water will aid on cooling the engine but lessen the corrosion resistance and increase the freezing point closer to 32 deg F.

Noting you live in FL one would feel its fine but you are 2/3 water. I would take the opportunity to balance the mix better.

Honda genuine coolant is always the best.

ive always used the cheapest 100% green coolant that autozone sells and then cut it myself with distilled water. thats all you need to do. why pay for the 50/50 mix when essentially youre paying for water at the rate of about 16 bucks a gallon. if its 16 bucks for a gallon of 50/50.
