I use “synthetic blend” oil which I think gives you a good balance between quality and price. Full synthetic oils are quite expensive! According to jdpower:
There is little doubt that synthetic oil offers superior engine protection under extreme operating conditions.

Change the oil at the manufacturer’s recommended interval (found in the owner’s manual) and your vehicle will reward you with a long service life.
