Coolant is NOT thirty dollars!

More like 16 for a gallon. Can we have a showdown or something about using/not using G12 in the B5?

You can, BUT
If any of that new coolant mixes with the old, it could get real nasty. Audi G12 isn't really compatible with any coolant you can get at the parts store.
If you go that route, be sure to flush out your coolant system really well first.

Don't listen to any nonsense about getting coolant from "the store"
Just go to the dealer and get some G12 and then to the grocery store for the distilled water. You're asking for expensive repair trouble by trying to save a couple bucks.

False.
"DEX-COOL" is a performance spec, not a formulation spec. Some antifreeze/coolant products which meet GM's DEX-COOL performance spec. (and just as importantly, are licensed by GM as having achieved that status) do differ in detail as to actual formulation. As an example, Prestone's licensed DEX-COOL formulation uses some combination of two hydrated organic acid salts: sodium 2-ethyl hexanoate and sodium neodecanoate, as the formulation's corrosion inhibitor package. The last time I checked, Havoline/Mr. Goodwrench DEX-COOL formulation uses potassium 2-ethyl hexanoate only. Whether Prestone's approach is superior, inferior, or merely equivalent to Havoline's is best left to smarter people than me to speculate on, but the Prestone approach, nevertheless, does satisfy GM's DEX-COOL licensing protocol. All OAT coolants are fully compatible including G-12.
