What distinguishes synthetic base oils from mineral base oils
Synthetic base oils are highly refined or chemically produced oil base substances that serve as the basis for high-quality lubricants, engine oils or industrial oils. In contrast to mineral oils, which are extracted directly from crude oil and merely distilled, synthetic oils undergo more complex manufacturing processes in order to specifically improve certain performance characteristics – such as temperature stability, ageing resistance or flow behavior.
Relevance in the industry
Synthetic base oils are a key element in the development of high-performance oils for demanding applications. In engine technology, hydraulic systems or compressors, they ensure reliable lubrication even at extreme temperatures. Lubricant manufacturers use different groups of synthetic base oils (e.g. PAO, ester) to formulate oils for specific requirements – whether in the automotive sector or in industrial production.
What are PAOs and esters in synthetic base oils?
PAOs (polyalphaolefins) are the most commonly used synthetic base oils with excellent cold and heat stability. Ester oils also offer high lubricating film resistance and a cleaning effect – ideal for extreme loads.
Are synthetic base oils better than mineral base oils?
In many respects, yes: they offer better oxidation stability, lower evaporation loss and consistent viscosity over a wider temperature range. This makes them more durable and efficient – especially in high-performance applications.
What does “fully synthetic” mean compared to semi-synthetic?
Fully synthetic oils consist exclusively of synthetic base oils, while semi-synthetic products contain a mixture of mineral and synthetic components. The latter are less expensive, but also less powerful.
