Well I know it is the cooling system....On my 7.3L, I think I added FW-16 or something??

Ford Premium Gold is the Motorcraft stuff. Zerex G-05 is the over the counter stuff. Some guys still check SCA's, others don't. The Premium gold is supposed to not need them. There are a few more extended life HOAT coolant fomulations out there from fleetgaurd and Chevron, but they're harder to find then the Zerex.
BTW- Don't belnd the older green & the gold or use the Dexcool at all. Causes major problems.
