Could anybody give advise about the dilution ratios of this fluid, please? The bottle doesn't list minus degrees, but says 1:5 for winter, and 1:1 for severe winter... I ended up with something closer to 1:4 than 1:5, but it froze up this morning Really disappointed; just filled up the entire capacity of the system (did use up all the fluid in it from before, and made sure the new fluid was washed through the hoses... )
Any advice would be greatly appreciated.
