Hello together, I added a Space Star 1.8, 74000km, year 2002. Prima vehicle – what was noticeable is the slightly squeaky steering. I read here that a special fat can remedy. Is there any current findings ? What does a Mitsubishi dealer require for this action? The previous owner has had to fill in oil at ATU 10W40. Is the standard oil for the 1.8 ok or recommends Mitsubishi full-syntethics? Look forward to your information.
