Long time did not post anything on this forum, because I was extremely busy in the past a few weeks.
Last week, I changed my engine oil on my own expense (the car is only 10000kms right now). After a week of driving with the new engine oil, I found I enjoyed the car more than before. What's the reason?
The vibration during complete stop at traffic lights is totally gone!!! Man, I suffered with it in the past 9500kms. I can confidently say the vibration has gone now.
Therefore, I am wondering what causes the vibration more. How can a simple oil change made a so big difference? Can anybody tell me what is the reason I had vibration but I do not have it now.
