u can use what ever just gotta flush the system first. i use green because its cheaper and it tastes better
i dont think we humans are the problem.. its that animals just love the sweet taste... then about half hour later they turn up dead, or very very sick depending on how much they ingested. :lol:
The real question here is which is better. ethelyne glycol or propelyne glycol. sorry for the sp. I cant remember which off the top of my head as we use g11 or g12 antifreeze on all VWAG cars at the shop. One is bad for engines with aluminum heads and the other is not.
