The 2019 Toyota Sienna has a 3.5 L V6 engine that needs 0W-20 Synthetic Motor Oil in all temperatures. It is okay to use 5W-20 if 0W-20 is not available however 0W-20 must be used the very next time. The capacity for the van iS5.7 quarts with a filter with O TT and 5.8 quarts with a filter with TT and the torque for the drain plug iS30 ft/lbs. It is important to use engine oil because it will not only help to keep the engine clean but it will help to lubricate parts to help with friction. You should change the oil and filter every 7,500 to 10,000 miles because it doesn't last forever. The cost of a change is between $40 to $50 in labor costs.
