The INFINITI G35 from 2003 recommends using SAE 5w-30 synthetic motor oil according to the owner's manual. Here are some interesting facts about engine oil that you may find useful. The "w" in motor oil stands for winter, indicating how well the oil flows in cold temperatures. For instance, a 5W- oil will flow better in the cold compared to a 15W- oil. The number following the "w" represents the oil's viscosity in hot weather conditions, indicating how thick the oil is at high temperatures. There are 11 viscosity grades of oil ranging from 0W to 60, with lower numbers being thinner oils and higher numbers being thicker oils. In the U.S., these numbers are often referred to as the "weight" of the oil, and single-grade oils are known as "straight-weight" oils.
