Synthetic Engine Oil
Synthetic engine oil is made from chemically refined or built base oils that stay stable over a wider temperature range than mineral oil.
What is Synthetic Engine Oil?
It flows better at cold starts and resists breakdown at high temperatures. Most modern engines and long service intervals require it. “Semi-synthetic” oils blend synthetic and mineral base oils. Fully synthetic oils with low viscosity, such as 0W-20, help cut fuel consumption in modern engines.
How it works
Uniform molecules and strong additives keep the oil film stable under heat and pressure.
Why it matters for your car
Use the viscosity and specification in the owner’s manual, not just the word “synthetic”. Synthetic oil still needs changing at the stated interval.
