6-1. Specifications Recommended viscosity: 2.5 L 4-cylinder (2AR-FE) engine SAE 5W-20 or 0W-20 SAE 5W-20 or 0W-20 engine oil may be used. However, SAE 0W-20 is the best choice for good fuel economy and good starting in cold weather. Outside temperature Oil viscosity (0W-20 is explained here as an example): ● The 0W in 0W-20 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 20 in 0W-20 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. 6 Vehicle specifications 507
