FW-15 coolant additive
I recently changed my coolant with 50/50 Zerox from Autozone. I asked about adding FW-15 and they said it is not necessary. However, the dealer says it is. Who is right and what is the purpose of the additive

I think there are a couple of reasons that come to mind. The extended life is more expensive than regular green, plus green can be found almost anywhere if you are in a bind. I dont think the extended life coolant was recommended for the 97 7.3 and I dont know why. I may be wrong on this.

get a set of fleetgaurd test strips to test the coolant additive, if you dont have any charge just buy some additive and throw it in, I've been using baldwin additive, dont know if its right or wrong but thats for preventing cavitation.
I dont know anything about Zerox antifreeze but thier is green anti-freeze on the market that is already pre-charged with the additive (diesil anti-freeze). The guy might be right for not having to add the additive but overtime from my expearence I've had to add a little to keep the charge up.
I also avoid at all cost in mixing antifreezes, if its green, add green. Thats my opionion.
Also, long time ago I read the way to go is use CAT extended service antifreeze, dont know if that still holds true though.
