The oil used in your car has two primary ingredients: base oil and additives. The base oil allows the motor oil to perform its vital function – lubricating the engine’s moving parts to protect them against wear and tear caused by friction. The additives provide additional engine protection by helping to prevent the oil from deteriorating under the engine’s extreme temperature conditions.
Synthetic oils contain a mixture of fluids and additives suitable for the most severe conditions and perform their duties under very high temperatures and pressures, where conventional mineral oils lose their effectiveness. Thus, synthetic oils are capable of performing well in a broader spectrum of use. Generally, oil is more powerful, plus it contains additives.
