What's the 2007 lexus es 350 engine oil type?

The 2007 Lexus ES350 houses a 3.5L engine, and works very well with fully-synthetic motor oils, although semi synthetic and conventional oils are perfectly viable alternatives. As for the oil type, 5w-30 motor oil is preferred, with the cars capacity beinG6.4 quarts. This is because a fully synthetic motor oil offers a greater degree of protection to the engine, much better fuel efficiency and management and ultimately, much more longevity to the car. It is for this reason that oils should be changed every 7,000 to 10,000 miles if using a synthetic oil. Changes should be made more frequently if using a conventional oil, with the general guideline being once every 3,000 to 5,000 miles.
