Shell or Mobil Oil for Japanese Cars?
1 Answers
Both Shell and Mobil oils are suitable for Japanese cars, provided that the correct oil grade is selected. Engine oil is a lubricant composed of base oil and additives. The functions of engine oil include: assisting in engine lubrication and wear reduction, cooling, sealing and leak prevention, rust and corrosion prevention, and shock absorption. Engine oils can be categorized based on usage conditions: 1. Diesel engine oil: selected based on the combined mechanical and thermal load of the car engine and the severity of engine operating conditions; 2. Gasoline engine oil: chosen according to the severity of engine operating conditions, additional devices in the car's intake and exhaust systems, and the production year. The hazards of using inferior quality oil are: 1. Degrading the oil quality, reducing its performance; 2. Damaging the lubrication of precision parts in the fuel pump and injector; 3. Reducing the power output of the generator set; 4. Affecting the combustion efficiency of the engine.
