Yesterday I went for my regular oil change. Previously using Mobil Delvac MX 15W40, and yesterday switched to cxxxxxe 5W40. I still have remaining 1 liter of Delvac MX, so I asked the mechanic to pour it in to flush out the remaining oil after draining out the old oil..... To my surprise, even when the old oil had been completely drained out, there is still much dirty oil inside the engine. Approximately 80% of the new oil (remaining 1 liter Delvac MX) that went in comes out as dirty looking as the old oil. It is only after the rest of the dirty looking oil had flow out, then the colour gets lighter looking. Having witnessed that, I wonder if the usual drain and refill method during oil change will be sufficient? Perhaps it will be good to occasionally use some fresh oil to flush out the remaining oil inside the engine during oil change? Any thoughts on this?
