Is the 4L package of SPOW20 engine oil fully synthetic?

[LeHarper]

SPOW20 engine oil in the 4L package is fully synthetic. SPOW20 refers to the viscosity at 100 degrees Celsius; the higher the viscosity, the better its resistance to high temperatures. Replacement interval for fully synthetic engine oil: Under normal conditions, fully synthetic engine oil can be replaced every 10,000-12,000 kilometers or every six months. However, the actual replacement interval depends on usage conditions. If the vehicle operates in a dusty environment, at low temperatures, or frequently makes short trips, the replacement interval for fully synthetic engine oil should be shortened to ensure smooth engine operation. Precautions for using fully synthetic oil: When changing the engine oil, it is best to replace the oil filter as well to prevent accumulated impurities from causing blockages. Additionally, the oil pan bolt should be replaced with each oil change, as it serves as a protective measure for modified engines or engines under prolonged high-load conditions.
