what grade of oil is used for 2015 Hyundai santa fe convetional or Synthtic
2015 Hyundai santa fe sport
Refer to the owner's manual for the proper grade and oil change interval. If you have a Hyundai dealership near you I would recommend them changing your oil versus the "quick" lube places.
Your engine is turbocharged and I would recommend synthetic oil. Mobil1 would be great.
