In recent years, many motorists must have noticed the growth in use of synthetic oils. Synthetic oils are made to a more highly refined specification. Hence, that of  standard conventional mineral oils. The improved refinement gives a higher protection and performance. Thus, of more conventional mineral oils.

For this reason the synthetic oils have a capability of giving modern vehicles better engine running at the top performance. Consequently, car engineers have been able to develop different types of oils for different engine types. Gone are the days that you can put any oil in any engine.

It is important to replace the recommended oil for your vehicle with the correct viscosity for your car. Therefore car manufacturers have all the engine oil specification listed in the handbook.

In short, the difference between conventional oils and older traditional oils. Is that traditional oil is just made by a regular method of refining crude oil. Synthetic oil is made by using advanced refining methods. As a result, this refining gives the synthetic oil a higher purity and a better quality oil. Synthetic oils have molecules that are more uniform. This gives more lubrication and less friction. Traditional oils, have molecules that are inconsistent in size. Therefore generating more engine friction.

Going back in time. I can remember that we had one oil tank that would be sufficient for all type and models of cars. The Castrol oils truck would come round when required and top up the tank. The tank contained 1000 ltrs. Now here at Pellon Autocentre in Halifax UK, we have to keep a few different types of  synthetic oils in stock. This is to make sure that the correct oil goes into the correct vehicle according to the car manufacturer’s recommendations.
