How many liters of engine oil does the Prado 3.5 require?

[MackenzieFitz]

Generally, add between 5.5 liters to 5.9 liters. Engine oil specification: The Prado uses 0W-20 fully synthetic engine oil, with a replacement interval of 5,000 kilometers. Refilling precautions: When adding engine oil, fill to between the upper and lower marks on the dipstick. Do not go below the middle mark, as high-speed driving heats the engine, thinning the oil. Too little oil reduces lubrication. Overfilling saturates the engine block with oil, creating unnecessary resistance for the crankshaft, affecting power output and increasing fuel consumption. Excess oil entering the combustion chamber increases carbon deposits, raising piston movement resistance and reducing engine power. Model introduction: The Toyota Prado is a mid-to-large SUV with a length of 4840mm, width of 1885mm, height of 1890mm, and wheelbase of 2790mm. Power comes from a 3.5L V6 naturally aspirated engine paired with a 6-speed automatic transmission, delivering 280PS maximum horsepower, 206kW maximum power, and 365Nm maximum torque.

I've been driving a Prado 3.5, and changing the engine oil is quite particular. According to the factory manual, the standard amount is around 6.5 liters, but in practice, it depends on how thoroughly the old oil is drained. For every maintenance, I use full synthetic 5W-30 oil, and with gravity draining, adding about 6.2 liters brings it to the middle mark. A reminder to everyone: don't just look at the liter amount; check the oil dipstick scale. After adding, start the engine for a few minutes, then turn it off and check again. When the engine is cold, the oil level should be slightly above the middle between the upper and lower limits. Before going off-road or on long trips, I always carry an extra half-liter as backup, since this vehicle consumes more oil than sedans.

Having done maintenance for over a decade, the oil change volume for the Prado 3.5 engine fluctuates between 6.2 to 6.8 liters. The key factor is whether you use oil extraction or gravity drainage - 6 liters is sufficient if there's significant residual oil left with gravity drainage. I prefer using original Toyota Genuine or Mobil 1 oil, with 5W-30 viscosity being the safest choice. A reminder to owners: always check the crankcase ventilation valve during oil changes; if clogged, it can cause abnormal oil consumption. If you notice the dipstick level drops by half a centimeter after 5,000 km, check for potential piston ring issues.
