[MacSara]

125 carburetor mixture concentration adjustment is quite good. Advantages of fully synthetic oil: Fully synthetic oil is one grade higher than semi-synthetic oil in terms of base oil selection. Difference in replacement intervals: Semi-synthetic oil needs to be replaced every six months or 7,500 kilometers during use; fully synthetic oil needs to be replaced every year or 10,000 kilometers during use. Fully synthetic oil has a wider operating temperature range. Under the same working conditions, fully synthetic oil can protect the engine with a lower viscosity, while semi-synthetic oil has relatively higher usage requirements.
