When should you change it? Understanding your car’s needs

All oils, no matter what their type, lose their viscosity or their protective role over time. When this happens, fresh oil is the solution, but how often is it necessary?

How often should you change your oil?

The more often you change it, the longer the engine will last. Engine oils are designed to meet car manufacturer requirements, and therefore need to be changed according to manufacturer recommendations. Castrol in New Zealand works with car manufacturers to ensure that we constantly providing new oils suitable to meet the needs of new car models.
Theoretically, the optimum time for changing oil should relate to a number of factors, and often the least important is how far your vehicle has traveled. Unfortunately, advised oil drain intervals are only averages, based on a typical type of driving. If driving conditions are more severe, a "classic" oil should be changed more frequently in order to maintain the maximum protection and cleanliness of the engine.
Castrol's products exceed the manufacturers specifications and guaranty outstanding protection of the engine in all type of driving and conditions.

Other factors to consider are:

  • Number of cold starts.
  • Ambient temperature.
  • Effectiveness of crank case scavenging.
  • Wear of the engine.
  • Accuracy of carburetion during warm-up period.
  • Quality of fuel.
  • Type of driving.

    • Tips:

  • Use your dipstick regularly.
  • Don't run below the 'min' mark on your oil gage.
  • Don't worry about the engine oil turning black.
  • Always follow the manufacturer's recommendation in your handbook.
