I'm way overdue to change the coolant in my ZR1 and started looking at my options. Has anybody recently looked at the lineup of Prestone antifreeze available these days! I was considering the "All Vehicles" mix for my ZR1 but It doesn't say it's compatible with the Dexcool however. Leave it up to these guys to make choosing antifreeze difficult. I'll likely use the Dexcool (5 years 150,000 miles) just to make sure It won't create a problem but tempted at using the "All Vehicles" or the "American Vehicles" (Orange). It says it's good for 10 years or 300,000 miles.

I just went with Dexcool when I replaced my radiator. I don't trust anything that claims it works in all vehicles. I'm no chemist but I know there are incompatible coolants out there. I agree, it's become way too complicated so rather than worry about it i just went with what GM put in it.

Only use the orange Dexcool.

No reason to overthink it; just go with Dexcool. I haven't had any issues and I have used it since 1994, including using it in other vehicles that didn't originally have it.

dexcool for the win

reasonable suspicion

I bought the 10-101 dexcool 12346290 for the radiator and the supercharger.

Thanks for all the suggestions. I'll use the Dexcool to be safe.

Use what GM recommends which would be dexcool
