What’s the difference? Well, a mineral oil (or standard oil) is produced from crude oil following the processing and removal of tar, petrol, diesel and kerosene by a distillation process and contains mainly hydrocarbons with some additives to improve the corrosion resistance, cleaning properties and pressure resistance of the oil.
Synthetic oils were first developed by German engineers during the early 1940s for their war effort as an alternative lubricant was required due to the lack of available crude oil for processing. The subsequent low temperature ability of the oil was significant on the Russian front where the crude based oils would solidify in the cold.
A synthetic oil goes further in the processing of the base oil by separating the very molecular components of the oil which is then recombined after the molecules have been manipulated with components from other carbon containing molecules, including coal, gas and animal bi-products. The resulting synthetic oil is thinner when cold for improved wear resistance on a cold start with improved heat characteristics so they do not thin as much at higher temperatures and also resist oxidation better.
All oils have additives to improve their motoring properties including the polymers mentioned earlier, detergents to keep the engine clean by keeping combustion and oxidation products in suspension in the oil, anti-oxidants to help combat oxidation in the oil as its temperature exceeds 100ºC, antifoamers to control the aeration of the oil and other additives, such as anti-wear ingredients. We are now seeing Low-Ash oils since the advent of the DPF (Diesel Particulate Filter) in diesels to reduce the ash particle build-up in the exhaust components. These additives can easily constitute around 20% of the total oil volume.
