Phosphate-free, silicate-free, nitrite-free, borate-free, OAT coolants are where it's at in the HD world; G-05 is old news, and can't hang with the new ELC's.
Horsepucky. In what sense can it "not hang?" Slick advertising? Sure, its only good for 50k instead of 100k, but on the other hand it actually protects a huge spectrum of metals and engines without harming composite gaskets. You can put it in pretty much any engine and not expect something bad to happen, UNlike so many of the more modern ELCs. Hunt up the recent thread showing a multi-hundred-thousand mile Benz radiator that looks brand new after nothing but G-05 for many years. And it protects diesels without needing an SCA. If you ask me, its Motorcraft Orange that "can't hang" with G-05. If you have to feed it SCAs every 10k miles, what's the point of a so-called "ELC?"
Looks like Orange has roughly the same change intervals as Gold did, 105K on factory fill, 50K on subsequent fills. Not sure if Ford might be doing a little "CYA" after the 7.3 IDI cavitation debacle, or not?
