Antifreeze/Coolant

Has anyone used this? https://www.commaoil.com/passenger-vehi ... 300/SCA5L/
It is 'traditional' and blue, not OAT. Any other suggestions welcome.

Looks like standard anti-freeze to me. Is there supposed to be something unusual about it?
I just found something about the chemical which surprised me: Its freezing point when neat is -12c but when mixed with water this drops to about -45c, depending on concentration.
I am probably the only person who finds this interesting. :roll:

There's been various threads before advising against using OAT antifreeze but apart form a Shell product I cant see any which reflect what other owners have used so I was just checking to see if I've missed anything as this is low cost compared even to Halfords own brand. Thanks for the input and I too am intrigued by the freezing point going down when you add water.

I would not be surprised if the Halfords product is a re-badged version of the Comma product. The Halford oils are re-badged Comma oils...

Watch your concentration~my local garage was keen for me to make sure the car could handle -10 degrees Celsius (in balmy Berkshire..)
