Advanced oils, lubricants and treatments since 1887
In the Millers Oils classic vehicle range, there are a number of different types of engine oils, which include mineral, semi-synthetic, and fully synthetic blends.
In the past there was concern around the use of synthetic oil in classic vehicles, however, modern technology has shown that this worry is misplaced.
Oils used to formulate lubricants are called base oils, and include both mineral and synthetic types:
Mineral oil is refined from a fraction of crude oil, using different techniques including solvent washing and chemical reactions to remove impurities and improve lubrication characteristics.
Synthetic oil, although still derived from crude oil, is made by chemical synthesis rather than the refining of crude oil. This is a much more controlled process, meaning that the molecules in the oil are more uniform and exhibit the following benefits:
In the late 1990s synthetics were a new and increasingly popular technology and oil companies started to use synthetics in their classic oils.
However, classic car owners began experiencing oil leaks, and it was discovered that there were compatibility issues with rubber seals on older vehicles that caused the rubber to perish and weep, leading to the leaks.
After much research and testing, we now know lots more about synthetic oil technologies. Millers Oils has developed synthetic products for classic vehicles that not only eradicate the past issues with rubber seal compatibility but also allow classic car owners to reap the benefits of modern technology.
