Hi, I just have a well-known problem, namely smear on the oil lid and on the plug but.. last Friday I had an oil change at A.., offer thought I is OK 1. Release waste oil and dispose of 2. Oil filter changes together with new seals 3. new oil complete services for 39,90€ but I found today that I have a huge smear collar, can it lie on the oil? Because before the oil change everything was OK, there was nothing because I am dependent on the car and almost t every Wednesday I got used to checking the car – all liquids are visible and, if necessary, fill up – light check – look after the profile – look briefly at the stage and look like the cart looks from below – etc today at the check then the smudge my Clio 1,2l 75 hp BJ 6/2001 and more than 200tsd Km on the speedometer times apart from the fact that I think that you distributed more oil on the engine than tipped pure, it can be here a wrong oil has been used or where comes from the smear
