* Engine damage: The incorrect viscosity and additive package can cause poor lubrication, leading to increased wear and tear, potentially catastrophic engine failure.
* Clogged oil passages: The different formulation can lead to deposits and sludge buildup in the engine, clogging crucial oil passages.
* Sensor malfunction: Diesel oil can interfere with the operation of various sensors in the petrol engine.
* Voiding warranty: Using the incorrect oil type will likely void any warranty on your vehicle.
Always use the type of engine oil specifically recommended by your car manufacturer for your petrol engine, as detailed in your owner's manual.
