Low Oil Level: Check the oil level and add more if necessary. Insufficient oil in the engine may cause the oil light to come on, especially during low-speed driving or idling. When you accelerate, the oil pressure temporarily increases, causing the light to go out.
Faulty Oil Pressure Switch: The oil pressure switch may be faulty, providing incorrect readings. A defective switch can send false signals to the dashboard, causing the oil light to illuminate even when the oil pressure is adequate.
Oil Pump Issues: Problems with the oil pump could lead to low oil pressure, triggering the oil light. A worn-out or malfunctioning oil pump may not generate enough pressure to circulate oil thoroughly throughout the engine. As the RPM increases during acceleration, the oil pressure might temporarily rise, turning off the light.
Oil Filter Blockage: A clogged or blocked oil filter can restrict oil flow, resulting in low oil pressure and illumination of the oil light. When you accelerate, the increased oil flow may temporarily bypass the blocked filter, raising the pressure and causing the light to go out.
Engine Wear and Tear: Excessive wear and tear on engine components like bearings and piston rings can cause low oil pressure. Worn-out engine parts lead to increased oil clearances, allowing oil to bypass critical areas and reducing overall oil pressure. The higher RPM during acceleration might momentarily increase oil pressure and extinguish the oil light.
Oil Viscosity: Using oil with an incorrect viscosity (thickness) can affect oil pressure. Too thick or too thin oil may not provide adequate lubrication and proper pressure within the engine. Choosing the right oil viscosity as per the manufacturer's recommendation is crucial.
Oil Leaks: Check for any oil leaks within the engine or underneath the vehicle. Significant oil loss due to leaks can lead to low oil levels and reduced oil pressure, triggering the oil light. The pressure might stabilize temporarily during acceleration due to increased oil circulation.
It's crucial to address the root cause promptly to prevent potential engine damage. If the oil light stays on or continues to come and go, it's best to have the vehicle inspected by a professional mechanic for proper diagnosis and repair. Ignoring this issue could compromise the engine's health and reliability in the long run.
