How Often Should Blue Shell Engine Oil Be Changed?
1 Answers
Blue Shell engine oil should be changed every 7,500 kilometers or 7-8 months. As a semi-synthetic oil, Blue Shell helps maintain engine cleanliness and reduces carbon buildup. The final oil change interval should be determined based on actual conditions such as vehicle condition, road conditions, and personal driving habits. Methods to determine if Blue Shell engine oil needs changing are as follows: Observe the oil color: If the oil color turns black or noticeable impurities float on the surface, it indicates the oil needs replacement. Monitor vehicle feel: If noticeable engine vibration occurs and the engine noise increases, it's time to change the oil. Oil test paper method: First, pull out the dipstick near the engine, take a small amount of oil, and drip it onto the oil test paper. Let it sit overnight until the oil fully diffuses on the paper. Observe the deposit ring, oil ring, and diffusion ring on the paper. If any of the following three conditions occur, the oil needs replacement. Distinct boundaries between the three rings: Can be used for a while but should be replaced soon. Oil ring disappears: Only the deposit ring and diffusion ring remain. Go to a repair shop or change it manually. Only a dark deposit ring remains: Replace immediately to avoid engine damage.
