Swift usually keeps common sense and seeks expert advice.

Generally 5000 kilometers or 6 months, whichever comes first, for maintenance. Swift maintenance details can refer to your instructions. As for engine oil, I personally think that mineral oil of this grade is enough, and yellow shell or Mobil Subba 1000 will do. However, it is recommended to choose 10w-40 in summer and 5w-40 in winter. The smaller the number before engine oil W, the better the frost resistance. The bigger the number, the better the viscosity, but the original oil of Swift is 10w-40, so it is still recommended not to change the oil of 30.

Some people will say that with 5w-30 engine oil, the car is obviously light and fuel-efficient, and it is easy to move when the glue is diluted. However, this parameter is actually related to engine design. Swift's engine technology is relatively old, too dilution may not completely take away the impurities of the engine, but also consider the clearance of engine parts and other reasons, which may cause oil loss.
