This is the conventional oil that is available in different levels of viscosity. This type of oil is largely used in light-duty vehicles, and needs to be changed/replaced once in every 4 months, or at least twice a year. It is highly recommended that the oil is changed as soon as the oil-change indicator in the car lights up.
This type of oil is specially formulated for sophisticated engines, such as those found in Mercedes-Benz. They promise a high degree of performance in aspects such as protection against deposits and viscosity index. They are considerably expensive than the conventional oils but are completely worth the money spent on them as they perform well across a wide range of temperatures.
Synthetic Blend Oil
As the name suggests, synthetic blend oil consists of a dash of synthetic mixed with the conventional oil. This type of oil is formulated with the aim to offer protection to vehicles enduring heavy loads and/or working in high temperatures, especially SUVs. Given that the synthetic blend oil doesn’t evaporate as easily, they reduce the loss of oil and increase fuel efficiency. Yet another benefit of this is that it costs much less than fully synthetic.
