| Abnormal pH value | 12% | Test paper shows strong acidity |
4. Professional maintenance suggestions
1.Replacement cycle: BMW officially recommends replacement every 4 years or 60,000 kilometers, but it should be shortened to 3 years in extreme climate areas
2.Mixed taboos: Antifreeze of different colors cannot be mixed. Blue (G48) and green (G11) will produce precipitates and block the pipelines.
3.Emergency treatment: When it is found that the liquid level is lower than the MIN line, distilled water should be added instead of ordinary tap water.

| Domestic brands | 40-60 yuan/4L | 17% |
It can be seen from the above data analysis that although third-party antifreeze has a price advantage, BMW owners prefer to choose original factory-specified products.
