JJ, Honda antifreeze is blue like a smurf. Yours is yellow?
Yes, I purchased a gallon as mines seems to use the quantity in the over flow bottle yearly.
I had an accident at 60k miles and new fluid plus radiator installed, both honda products. Well checking the fluid when I did the plugs at 100k I noticed rust in the fluid. I went ahead and flushed, replaced t stat and refilled. The new radiator had crap settled in the botton blocking the pet cock.
I buy either peak or prestone, which ever is on sale and mixed.
