OIL CHANGE

Since additives in the oil get depleted and the contaminants level in the oil continually increases, the engine crankcase must be drained at regular intervals and refilled with clean oil. The rate of contamination varies with driving conditions, but because the individual would find it impractical to determine when the contaminant level is too high, it is recommended that he follow the manufacturer's guidelines. The manufacturer may recommend changing the oil at least every 7,500 miles or 6 months. However, the oil and the filter should be changed more often if driving in dusty conditions, if there are extended periods of idling or low-speed operation, or when driving for a long time in cold temperatures or short distances only. In such cases, the oil and filter should be changed every 3,000 miles or 3 months. The filter must be changed every time the oil is changed. The article illustrates with photographs how the oil/filter change may be effected.
