  • The cold viscosity of engine oil for Mazda 3 (number in front of the letter “W”, which stands for “Winter”): This value will show the engine’s ability to start cold depending on the viscosity of the oil. 0W means -30°C; 5W means -25°C, 10W means -20°C and 15W means -15°C. It is consequently up to you to adapt it to the climatic conditions in which you drive your Mazda 3.

The different types of engine oil for your Mazda 3

  • “Mineral” engine oils 15w40: They are called mineral oils because they are principally made from crude refined oil, which will give them maximum viscosity and consequently a thickness suitable for old engines that often consume oil. However, the truth that they are natural will cause them to lose their lubricating properties more fairly quickly, so it will be required to shorten the intervals between oil changes.
  • Semi-synthetic 10w40: This oil has a good quality/price ratio and is said to be semi-synthetic because it is still made up of specific components that will boost its life expectancy. It is thus appropriate for a polyvalent use of its car. Additionally, it favours a simpler cold start than a mineral oil. On the other hand, you should remember to replace the oil every 10, 000km.
  • The “synthetic” oil 5w40: This type of oil is really adapted to the recent Mazda 3 engines, in truth, the protection of the engine unit will be maximum and the cold start too. It is consequently a good choice either for people who drive in city centres, who have a sporty driving style, or who drive long distances and want to reduce the frequency of their oil replace.
