The only thing that I see is that under the specs the very 1st thing it says is "Ethyl glycol" and I don't see it listed on the Zerex G-05. I'm not sure if that even matters.
The Valvoline Zerex Original Green Antifreeze/ Coolant https://motorcareguys.com/best-antif...iginal%20Green does show it and is for aluminum engines as well as Havoline Xtended Life Antifreeze/ Coolant https://www.amazon.com/dp/B00M1Y7QJQ...ogi&th=1&psc=1 Unless someone see something that I didn't either of these would work along with Dexcool (At least the Shell Dexcool) I only read up on the Shell Dexcool.
So it looks like there are several options out there. Again for me "I would never mix coolants" from one brand to another.
