"Understanding the Role of Engine Oil Filters: Keeping Your Engine Running Smoothly"

                             What is an engine oil filter?

 This part removes the carbon, sludge, and metal particles in engine oil. 

If the engine oil filter is not replaced

 If the filter is clogged, oil cannot flow through the filter. Then the relief valve opens and sends the dirty oil into the engine.

Replacement interval

• Replace the engine oil filter according to the distance driven or the amount of time because it is impossible to judge the level of deterioration by looking.

   Replacement (on Corolla for general countries):

   every 10,000km (6,000 miles) or 1year

• Refer to the maintenance schedule because the changing interval varies by model and usage condition of the vehicle.
