Does the 2009charger need a full synthetic or blend?

The 2009 Charger uses fully synthetic oil. The 2.7L v6 engine, 3.5L v6 engine, and 5.7L v8 engine use the 5w-20 synthetic motor oil and the 6.1L v8 uses the 0w-40. Engine oil also prevents contaminants from accumulating inside the engine. The oil filter also needs to be replaced regularly, because over time it loses its ability to filter the oil. It is recommended that You change the engine oil and filter every 3500 to 6000 miles. The average cost for an oil change is between $100 and $155. You can also purchase Your own oil at Autozone or Walmart and do Your own oil change by Yourself, at home.
