Well done. ICE will always burnt engine oil; it is just a matter of “how much of engine oil is burnt” > manufacturer’s specified. Then the engine may have problems of leaking gasket/poor seal of piston ring/defective valve~need mechanic to address whichever the problem is then.
That’s the typical answer from the mechanics I got every time when I went for servicing..when I asked a question, the mechanic will always said “不用但心, 这是正常的..什么赛都是正常的…but when there is problem with the car then they will said why you never come early to rectify the problem…😠
