Actually, the Commander doesn't use a special coolant, well no more special than any other new vehicle and arguably the most common of the new vehicles because this HOAT has been used in just about every new Ford, Chrysler and Mercedes Benz for the last 10 years or more.
But, the aftermarket antifreeze market has been a mess since manufacturers started developing long life anti-freeze, and I would NOT trust a single claim on any of the bottles unless I see enough independent evidence to prove its true.
Zerex G-05 is the aftermarket equivalent of Chrysler/Ford/MB HOAT, considering most of the Dealers are selling fluids at reasonable prices, if you can't find Zerex G-05, yea go to the dealer and buy the Chrysler HOAT.
The European manufacturers other than Mercedes Benz have their own version of HOAT. You probably have to go to the dealer for their version, G-05 should mix fine with them, and always follow the sooner replacement schedule of the two if you mix them. But I wouldn't risk it, either buy the right stuff from the dealer or drain and flush to change it out totally is the only safe way to go.
GM and the Japaneses use their own versions of OAT antifreeze, only GM uses the problem and incompatible with others antifreezes "2EHA" in their DexCool. The only specific OAT antifreeze being sold on the aftermarket that I am aware of is DexCool and it does NOT mix with any other antifreeze, including other OAT antifreezes. The "2EHA" in DexCool will soften and disolve plastic and rubber in older vehicles and vehicles NOT recommended for it, all OAT antifreezes will NOT protect brass, bronze and other metals in the cooling system of older vehicles or those NOT recommended for DexCool, although most new vehicles have eliminated those plastics and metals from their cooling system that won't work with DexCool, its NOT a guarantee. All other antifreezes prevent corrosion by coating the surfaces in cooling system, except OAT antifreezes, the fluid has to be in contact with the surface to prevent corrosion, so if there are any air bubbles in the cooling system corrosion will happen and fast. Dexcool is notorious for a cooling system that develops a leak and getting air in it, and as it goes unoticed, gunking up the entire cooling system with massive amounts of corrosion. And because of that, any OAT is a poor choice for a vehicle NOT recommended by its manufacturer to use OAT antifreeze, and DexCool the least of all antifreezes.
The old universal original Green (IAT) antifreeze, arguably it protects better than all the new antifreezes, PROVIDED YOU FOLLOW THE INSTRUCTIONS, which no followed the instructions, that is why we now have a dozen different new long life antifreezes. It is a good candidate to retrofit to any vehicle, if you drain and flush all the old out, don't mix antifreezes (although HOAT is very tolerant to mixing with the old Green antifreeze), PROVIDED YOU FOLLOW THE INSTRUCTIONS. That is too change it every 2yr/30k miles and only mix it with distilled/demineralized water.
And what does Automotive Aftermarket do? Well since no one is holding them accountable, they go out and market DexCool with "2EHA" as a new universal antifreeze, which it is anything but.
