It is acceptable to change fully synthetic motor oil once a year. Fully synthetic motor oil appears as a clear, semi-transparent or transparent liquid with a shelf life of up to 5 years. Synthetic motor oil is chemically engineered lubricant whose composition can be adjusted according to different usage purposes. The replacement procedure for fully synthetic motor oil is as follows: 1. Start the vehicle engine for preheating; 2. Unscrew the drain plug; 3. Remove the oil filter; 4. Apply new oil to the gasket of the new filter; 5. Pour new oil into the oil pan; 6. Check for leaks at the lower part of the engine and verify oil level with dipstick before starting the engine for testing.
