Hi  Does anyone have any problems with the oil level on a 2015 2 litre business edition avensis. With no obvious leaks it’s using about 2.5 litres of oil every 3000 miles. Exhaust looks clean and power appears normal. Oil inside the filler cap also looks ok. If a little black.  With 8500 miles to go to a previous service the oil light came on and it needed 5 litres of oil. It’s just happened again 3500 miles after the most recent service. It’s only done 67000 miles.
