Drivers of the Toyota Corolla may notice excessive oil consumption between oil changes, even to the extent of the engine oil warning light displayed on the multi-function display.

This issue is known to be caused by infrequent oil changes causing engine sludge, or worn piston rings.

The engine should be cleaned of oil sludge, and if oil consumption remains excessive, the engine may need new piston rings, or other internal components replaced.

To avoid this issue, change the engine oil and filter every 3,000 miles, and ensure the proper grade of oil is used.
