Works great on these late gen Saab 9-3s

Great stuff for one of my Saab 9-3 Aero V6s…. Never mix this with anything else, they're sensitive that way.

Works Great!

Picked this up because I was low on Antifreeze. Comes in a 1 gallon container. Ready to use and pre-diluted 50/50. It states it is organic and it's OEM approved. Works for GM so I researched and it says it is safe for my vehicle, an 09 Pontiac Vibe. No issues so far. So far so good. I would recommend, just check for the vehicle, each is approved for rack make. I would definitely recommend. No need to mix or risk danger.
