Full Synthetic Car Engine Oils

What is full synthetic engine oil?

Synthetic oils are chemically synthesised to meet the exacting demands of modern engines. This makes them more expensive to produce, but because they are tailor-made they provide the best performance, protection and fuel economy. They also remain stable at very high temperatures and fluid at very low temperatures.
