50/50 Antifreeze

[William2]

I have been mixing blue antifreeze in a ratio of 50/50 with de-ionised water. Is that the recommended mix for the UK is it it overkill?

In military we mix 50/50 apparently gives protection down to -36?

Most (concentrated, not pre-diluted) antifreezes recommend 50/50 which should be more than ok for temperature but just as important is that it is of sufficient strength for its corrosion pack to work properly. Specs / instructions should be on the label or online data sheet.

yesterday the wheeler dealers mechanic used some antifreeze which needs NO water: no corrosion AND no thermal expansion (open the top any time!) sandy
