Ive recently done an oil change, and sump removal and pickup check on my 3.0 v6, but now im running into a problem. This car had an oil level senosr fault when i bought it, so replaced it with a new one, which cleared the sensor fault on the DIS, but now im getting the yellow low oil message. My understanding is this engine holds 6.2 litres of oil, which i have put it, but cannot get the oil to show on the dipstick. I even added another 500ml but still nothing. I dont want to overfill, If i have to ill remove the sump again and check the dipstick is fully going in. Have i put the right amount in?
