I have a 2004 santa fe what kind of motor oil and multi grade you recomend for this SUV thanks

Use exactly what weight is listed in your owner's manual or on the oil fill cap. More than likely you will find it requires 5w20 weight. I personally use Pennzoil and have for over 30 years with not one internal engine problem. But any major brand will be good. Also very important is the filter. Use a quality filter such as Purolator, Wix, or Bosch and avoid cheap filters. I personally use Purolator Pure One filters. Change your oil and filter every 5,000 miles and your engine will give you great service. Also change the Air Filter every 30,000 miles as it is very important to keep it clean. Change your fuel filter, if changeable, every 50,000 miles. Some vehicles have permanent fuel filters.
