Can the Xiali N3 use fully synthetic engine oil?
2 Answers
Xiali N3 can use fully synthetic engine oil. Synthetic engine oil: It is an engine oil manufactured by humans using chemical synthesis methods. Depending on the intended use, the composition of synthetic engine oil can be adjusted. The development of synthetic engine oil began in the 1930s. At that time, due to the harsh operating conditions of aircraft engine oil, a higher-performance oil was required, leading some chemical plants to begin developing and producing synthetic engine oil. Characteristics and classification of synthetic engine oil: Synthetic engine oil is a product of modern chemical technology advancements. Synthetic engine oils have many advantages. For example, they offer better lubrication than mineral oils, lower friction resistance, are less prone to oxidation, and have stronger cleaning properties. Semi-synthetic and fully synthetic engine oils are two classifications of engine oils (fully synthetic oils contain no mineral oil components, while semi-synthetic oils contain some). The main differences between them are: fully synthetic oils can operate over a wider temperature range and have a longer service life; for the same oil film requirements, synthetic oils can achieve the desired performance with lower viscosity, whereas semi-synthetic oils require a relatively higher viscosity to meet the same requirements. In other words, under the same operating conditions, fully synthetic oils can protect the engine with lower viscosity. Similarly, in the same working environment, fully synthetic oils have a much longer service life than semi-synthetic oils, so although the cost is higher, when considering the reduced frequency of oil changes, the overall cost is not significantly higher than that of mineral oils. Characteristics of fully synthetic engine oil: Fully synthetic engine oil offers better high and low-temperature performance; has a longer oil change interval; and is suitable for more severe driving conditions.
I've been driving my old Xiali N3 for five years and have used full synthetic oil several times. Using full synthetic in an old car is quite dependent on the car's condition. If your engine is in good shape with no oil leaks or burning oil, 5W-30 full synthetic is perfectly fine. However, be cautious with older cars over 150,000 kilometers—full synthetic flows too well, and aged rubber seals might lead to oil seepage. Last time after changing, I noticed oil stains in my parking spot and quickly switched back to semi-synthetic. My advice: keep a cheap oil on hand when trying full synthetic for the first time. If the engine burns oil, you can mix them to avoid wasting hundreds on expensive oil.
