The oil pressure indicator light comes on when the car is driving at low speed

There are three reasons for this phenomenon: 1. The engine oil has been used for a long time and has lost its viscosity and has become thinner, so the oil pressure gauge indicator light comes on at low speeds. 2. The lack of engine oil causes insufficient oil pressure. 3. The replaced engine oil is the same as the one used before. Depending on the brand, the leakage occurs in the small hole of the oil sensor plug. Solution: 1. Remove the oil sensor plug and throw out the oil and blockage inside. 2. Replace the oil sensor plug to ensure that your oil pressure gauge does not have problems again. Remember to add points! Ha ha!
