What is meant by the term fully synthetic in Havoline Fully Synthetic?
Most engine oils are blended from conventional mineral base oils, extracted from streams produced in the refining of crude oil They are a complex mix of many different hydrocarbon compounds, some having very desirable properties for lubrication, some less so. In the processes used to manufacture synthetic base oils however we produce a finished product very different from the components of the starting material, and in doing so have a much higher degree of control over the types of compounds that appear in the finished base oil.
