[MadelynLee]

Castrol engine oil is divided into 3 grades. Castrol's products are categorized into three series: Edge, Magnetec, and GTX. Their quality ranks from high to low as: Edge, Magnetec, GTX. Castrol's main engine oil products for gasoline engines include: Edge Titanium Full Synthetic, Magnetec, and GTX. The specific introductions are as follows: 1. Edge Titanium Full Synthetic: As the name suggests, this engine oil is closely related to racing. It is a fully synthetic racing engine oil that helps the engine deliver powerful performance. 2. Magnetec: During the period from vehicle start-up to warm-up, when the oil has not fully covered the component surfaces, wear is particularly high. Magnetec's UMA magnetic molecules can adhere to the engine surfaces like a magnet when the car starts, significantly reducing engine wear during start-up.
