I was able to score a bottle of this Mazda coolant(green color) for free :P
It says, safe for all aluminum engines.
Can I safely use it in my Japanese(yamaha) motorcycle, as well as my Honda Civic?
I started this thread regarding MB coolant, https://bobistheoilguy.com/forums/ubbthreads.php/topics/4477328#Post4477328
Which one would be a better choice for a motorcycle?
Provided I'll drain all coolant and then will flush with distilled water.
Thanks for the advice and help
