Can Semi-Synthetic Engine Oil Be Changed Once a Year?
1 Answers
Semi-synthetic engine oil should not be changed only once a year; it is recommended to replace it every 7 to 8 months. Otherwise, it may deteriorate easily, leading to increased carbon deposits and, in severe cases, oil burning issues. The replacement cycle for semi-synthetic oil is approximately 7,500 kilometers, so it's advisable to change it on time. Different brands of engine oil have varying formulations, resulting in differences in viscosity, anti-wear properties, corrosion resistance, anti-knock performance, and volatility. Mixing different brands may cause incompatibility or reactions, so oils of different brands should not be mixed. Semi-synthetic oil is one type of automotive engine oil, made using semi-synthetic base oil.
