The criteria that differentiate engine oils for Mazda CX 7?

.
The function of the engine oil in your Mazda CX 7 is to lubricate your engine to make certain that all the gears in it can run properly , and to preserve the integrity of each of its components. In addition, this oil, which will limit all friction, will have other functions such as preventing corrosion, helping to dissipate heat in the engine and guaranteeing sealing . These oils can be purchased in 5 litre cans. We will now look at the different criteria for purchasing engine oil for Mazda CX 7 :

  • The cold viscosity of engine oil for Mazda CX 7 (number in front of the letter “W”, which stands for “Winter”): This value will reveal the engine’s ability to begin 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 therefore up to you to change it to the temperature in which you drive your Mazda CX 7.
  • The hot viscosity of the engine oil for Mazda CX 7 (value following the “W”): Value between 20 and 60, it is necessary to keep in mind that the higher the value, the thicker the layer of oil you will have when hot to protect your engine, and the lower the value, the less friction you will have when hot and therefore lower your consumption. Nevertheless, if you use your Mazda CX 7 in the city, or with a sporty driving style, it’s better to protect it while hot.
  • The standards : They are made on the back of the oil canister you can find them such as “ACEA C1 – C4” or “VW 500. 01”, are only standards of compatibility with different brands of cars, you have to check in the manual of your Mazda CX 7 that the oil in question is suitable for your engine.
  • Oil brands: Please take note that the brand should have very little influence in your judgement, there are enough objective criteria in the composition of motor oil for Mazda CX 7 to avoid having to focus on a subjective qualifying measure such as the brand, some car producers have partnerships and will recommend you on certain brands, but it is not required to stick to these suggestions.

The different types of engine oil for your Mazda CX 7

  • “Mineral” engine oils 15w40: They are named mineral oils because they are mainly made from crude refined oil, which will give them maximum viscosity and therefore a thickness suitable for old engines that often consume oil. However, the fact that they are natural will bring about them to lose their lubricating properties more 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 several elements that will boost its lifetime. It is thus appropriate for a polyvalent use of its car. Additionally, it favours a simpler cold begin than a mineral oil. On the other hand, you should make sure to replace the oil every 10, 000km.
  • The “synthetic” oil 5w40: This type of oil is really adapted to the recent Mazda CX 7 engines, in fact, the protection of the engine will be optimal and the cold begin too. It is therefore 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.
