SC400, SC300-1.5 (1.6, 1.3) NOTICE Avoid overfilling, or the engine could be damaged. Check the oil level on the dipstick once again after adding the oil. Engine oil selection Use API SH, Energy-Conserving II multigrade engine oil or ILSAC multigrade engine oil. Recommended viscosity (SAE): If the oil level is below or only slightly above the low line (low level mark), add engine oil of the same type as already in the engine. Remove the oil filler cap and add engine oil a little at a time, checking the dipstick. The approximate quantity of oil needed to fill between the low line (low level mark) and the full line (full level mark) on the dipstick is indicated below for reference. SAE 5W-30 is the best choice for your vehicle, for good fuel economy, and good starting in cold weather. If you use SAE 10W-30 engine oil in extremely low temperatures, the engine may become difficult to start, so SAE 5W-30 engine oil is recommended. 188
