Synthetic base oils have a number of advantages over mineral base oils. The uniformity of the synthetic oil molecules improves the thermal stability and reduces oxidation of the oil. Controlled molecular structure also results in lower volatility and a more stable vicosity over the life of the oil.

Most diesel engine oils carry a higher specification rating than petrol engine oils and vehicle manufacturers often specify a diesel engine oil be used in a petrol motor. This does not work in the reverse, petrol only engine oils cannot be used in diesels. Some engine oils carry both petrol and diesel specifications.

All engine oils contain detergent and dispersant additives which remove contaminant build-up inside your engine. When new oil is added to an engine these additives strip away build-up and hold the contaminant in suspension so it can be removed when the oil is drained, this does discolour the oil.

SAE is the Society Of Automotive Engineers (USA). The SAE rating of an oil is a measure of its viscosity (eg 20W50).

API is the American Petroleum Institute. The API rating of an engine oil covers the performance rating of the oil (e.g. SM for petrol, CF for diesel).

ACEA is a European industry body up of European vehicle manufacturers. The ACEA rating of an engine oil of covers the performance rating of the oil (e.g. A3/B3, C3).
