What Causes the Oil Can Light to Illuminate at Startup and Then Disappear?
1 Answers
Car oil can light comes on and then goes off due to: 1. Insufficient engine oil level; 2. Overheating engine causing oil thinning; 3. Damaged oil pump components or excessive clearance from wear/assembly issues; 4. Improper clearance between crankshaft and bearings; 5. Clogged oil filter or oil pickup screen; 6. Faulty or failed pressure relief valve; 7. Incorrect oil grade selection; 8. Oil leaks or blockages in oil passages. Only proper oil pressure ensures lubrication reaches all engine friction surfaces. Abnormal pressure (high/low) affects engine operation and may cause component damage. Immediately stop the engine when oil light activates to diagnose issues before continuing operation.
