I took my 2016 Sorento EX 2.0T to the dealership for an oil change, knock sensor software update and some other minor complaints. I brought my own Pennzoil Ultra Platinum 5w-30 which they had no issue using. The jug was 5 liters so I was expecting to get it back with a bit of oil left over. I did not get the jug back so I assume they just dumped it all in. I believe the reservoir is 4.8 liters. The level on the dipstick is about 1/4 inch above full. Am I okay running it here or should I drain a bit (which would be a PITA!)?
