Looks like I had green coolant in there but my local auto store only had:
Prestone® MAX European Vehicles (Blue) Antifreeze + Coolant
Am I screwed? Should I drain it ASAP?
Edit: the large tank was basically empty so I doubt any mixed yet but there was still some in the smaller tank
Color doesn’t indicate coolant type. The blue OP used might not necessarily be a G48 equivalent. OP should figure out first if it’s a G48 equivalent.
