I performed a coolant flush on my 2014 Buick LaCrosse and decided to go with this ACDelco Dexcool 50/50 premix. It’s what my GM vehicle calls for and what better to get for it than the ACDelco branded product! Some people don’t care for Dexcool but I’ve personally never had any issues with the stuff in any of my GM products, and I’ve had lots of them over the years. Simply change it every few years and it’s fine. So anyway it’s been a few months/few thousand miles since I did the coolant flush and no issues with it whatsoever thus far.

This was actually a good thing to order on Amazon. I needed some modern coolant for my car and I didn’t trust the no-name knock-off stuff and I ordered this instead and what I got was what I ordered and it seems to be fine.

I needed some to top off my GM vehicle and they don’t sell it by the quart so this was priced right and I bought have enough for years
