How to Determine When Engine Oil Should Be Changed?
1 Answers
Here are the methods to determine when engine oil should be changed: 1. Observe with an oil test paper. Take a small amount of oil from the dipstick and drip it onto the oil test paper, then let it sit overnight, waiting for the oil to fully diffuse on the paper. The harder the edges between the oil ring, sediment ring, and diffusion ring, the more the oil performance has degraded. 2. Judge based on the driving feel after an oil change. Engine oil performance has a 'shelf life.' At a certain point, if you feel the power is 'sluggish' and acceleration is slower, it indicates the oil's 'shelf life' has been reached, and it's time to change the oil. Additionally, if you notice a significant improvement in power after changing the oil, it means the last oil change interval was a bit too long. Next time, you can consider changing the oil 500 kilometers earlier. After 1-2 times, you can find a more accurate oil change interval. A reminder to everyone: when changing the oil, it's best to replace the oil filter as well. The oil filter's role is to trap impurities in the oil. If not replaced in time, accumulated impurities can cause blockages. At best, it may lead to insufficient oil pressure and poor lubrication of mechanical parts; at worst, it can cause excessive engine wear.
