What's the 2015 lexus is250 oil type?

The 2015 Lexus IS250 uses 0W-20, which gives the best balance of fuel economy and ability to start Your vehicle in cold weather. However, in a pinch, You can use 5W-20, though You should go back to 0W-20 on Your next oil change. You should also use a fully synthetic or blended synthetic; using a conventional in a Lexus IS unwise: You miss out on the additives and other agents that a synthetic has, which keeps Your engine healthy and humming. You'll need 6.8 quarts to fill the reservoir after You have the oil and filter changed, and You should do changes every 10,000 miles. The oil drain plug torque for the IS250 iS30 pound feet; that gives You a pretty high buffer, but You still should be careful not to over-tighten.
