6-1. Specifications 4.0 L V6 (1GR-FE) engine SAE 5W-30 SAE 5W-30 is the best choice for good fuel economy and good starting in cold weather. If SAE 5W-30 is not available, SAE 10W-30 oil may be used. However, it should be replaced with SAE 5W-30 at the next oil change. Outside temperature Oil viscosity (5W-30 is explained here as an example): ● The 5W in 5W-30 indicates the characteristic of the oil which allows cold startability. Oils with a lower value before the W allow for easier starting of the engine in cold weather. ● The 30 in 5W-30 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (one with a higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditions. How to read oil container label: The ILSAC (International Lubricant Standardization and Approval Committee) Certification Mark is added to some oil containers to help you select the oil you should use. 456
