Question
I have a 02 Yukon Denali have 45,000 miles. Will It hurt to use syntheic oil? I have always used 5W-30. What are the benefits of syn. oil?
Hello Howard, I use "Mobil 1" in all my cars and change oil at 5000 miles or 2 times a year. I think it is a better oil and really good when it is cold outside. A lot of new cars and trucks are now using it and recommended by GM.
Have a Great Day
