  2. Semisynthesis is obtained by mixingmineral and synthetic species. This is a more expensive option, but the quality compared with its previous form is incomparably higher. Optimal is its use for cars with a range from one hundred to five hundred thousand kilometers.
  3. Synthetics are synthesized chemically. This oil does not change its properties either at high temperature or low, so it can be used in any weather.
