■Engine oil consumption

A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.

• When the engine is new, for example directly after purchasing the vehicle or after replacing the engine
• If low quality oil or oil of an inappropriate viscosity is used
• When driving at high engine speeds or with a heavy load, when towing*, or when driving while accelerating or decelerating frequently
• When leaving the engine idling for a long time, or when driving frequently through heavy traffic

*: Vehicles with towing package

■Engine oil level rise

If the vehicle is repeatedly driven without the engine warmed up, moisture caused by dew condensation inside the engine or fuel which did not burn mixes into the engine oil, resulting in a rise in engine oil level. However, this is not a malfunction.

For example, the engine become difficult to be warmed up in the following situations.

• When driving a short distance
• When driving at a low speed
• When the outside temperature is low

When checking the engine oil, make sure that the engine is warmed up. If the engine oil level exceeds the refill upper limit mark, contact your Toyota dealer.
