How much antifreeze reduction per year is normal?

[KennedyMarie]

Under normal circumstances, a reduction of about 10%-36% in antifreeze per year is considered normal. If the coolant level drops below the minimum mark within a year, it is mostly abnormal unless it's for commercial vehicles that are frequently used, where coolant consumption would be relatively faster. Precautions for using antifreeze: 1. Choose antifreeze according to vehicle requirements: Generally, imported vehicles, domestically produced vehicles, and high-end vehicles should use permanent antifreeze (2-3 years), while ordinary vehicles can use direct-use antifreeze, and softened water can be used in summer. 2. Select antifreeze based on the number and concentration of vehicles: For units and departments with a large number of relatively concentrated vehicles, small-packaged antifreeze concentrate can be chosen. This type of antifreeze concentrate has stable performance, and the small packaging makes it easy to transport and store.
