What is the difference between a mineral and synthetic oil?

Both types begin with crude oil.  Mineral oil is obtained directly from the refining process, whereas synthetic oils are subjected to chemical processing which alters and improves its chemical structure. Synthetic oils therefore have better performance than mineral oils at higher and lower temperatures, but are inherently more expensive.

Millers Oils produce many different mineral, semi-synthetic, synthetic and nanotechnology oils.  Please see our online shop and product information pages for details of all available products.
