Yesterday when i go to mechanic at Suzuki service center, mechanic suggest me to change oil filter as well. I was ok with his advice. He also asked to get 1400ml engine oil as more oil is required with oil filter change. That is where he was wrong. We need to have 1200ml engine oil to change. There is a simple tip to remember that you need as much as that engine oil gauge not show more than higher level. It is also advised by owner manual.
