i buy long life pink/red concentrate bmw branded is so expensive and its not concentrated,
below link, 5 litres make 10 litres ie mix 50/50 or even neat wont hurt it, i tend to run my cars neat as less water in it its water that causes rust i feel. in very cold places they are run neat anti freeze so wont hurt nothing,
