What's the 2006 jeep grand cherokee laredo 3.7 Oil type?

The 2006 Jeep Grand Cherokee Laredo with the 3.7L motor uses SAE 5W-30 engine oil in the vehicle. Jeep recommends that You use synthetic oil whenever You need to change it. There are two main types of oil on the market these days, synthetic and conventional. Synthetic is engineered in a lab to give You greater wear protection and longer life than the standard petroleum based conventional option. This means You can usually go 7,500 miles between changes compared to the 3,500 to 5,000 miles with conventional. I recommend checking Your oil at least once a month to make sure that it is full. You should also make sure that there is not any visible debris or signs of burning.
