No, mixed antifreeze does not lose its strength when stored in vehicles as long as it remains within its specified lifespan. Typically, modern antifreeze mixtures have a lifespan of around 2 to 5 years before they start losing their effectiveness. When properly stored and maintained in a sealed container, the freezing point depression and other protective properties of mixed antifreeze remain stable within this stipulated period.
Remember to always follow the manufacturer's recommendations for proper antifreeze storage and periodic inspections during vehicle servicing to ensure optimum engine protection. Improper usage or exceeding the recommended lifespan can reduce the effectiveness of the antifreeze mixture.
