What's the 2002 nissan sentra oil type?

The 2002 Nissan Sentra uses SAE 5W-30 engine oil. Nissan recommends that You use synthetic oil whenever You need to change it. There are two types of oil that are on the market these days, synthetic and conventional. Synthetic is a newer technology that offers greater wear protection and longer life compared to the petroleum based conventional option. This means with synthetic oil You should only need to change it once every 7,500 miles compared to 3,500 to 5,000 miles with conventional. You should check Your oil at least once a month to make sure that it is free from signs of debris and is full. If You notice metal in Your oil that could be a sign of damage to Your engine components.
