Hi everone its happened a few times turn car off, peep yellow oil light comes on . Check level looks a bit short not much, top up its ok for a couple weeks then its away again .Does parking on a slope affect the sensor ? I am not doing a lot of miles a week about 150 or so does the 3.0 engine require oil on a regular basis .The car is performing perfectly as far as i am aware, or am I not putting plenty of oil in when i top it up
