I recently completed a 4,500 mile run in my 17 SantaFe with the 2.4 engine with Valvoline Modern Engine 5-30. I had a dramatic increase in oil consumption. Had to add a half quart every 1,500 miles. Changed back to Quaker State 5-30 syn and have not had any oil use now in 1,000 miles.
That is a mid SAPS oil and I don't know if that would have anything to do with it? I just changed out Valvoline Synthetic Maxlife 0w20 from my Hyundai GF4D Gamma 1.6L and much to my surprise it consumed a half quart over 4000 miles. I will be lowering my OCI to 3000 miles to see what the results are.
