Using oil with too low viscosity in your engine will result in what?

Choosing oil with too low viscosity for your engine can lead to low oil pressure readings. Viscosity refers to the thickness of the oil and its ability to flow at different temperatures. When oil has low viscosity, it does not provide adequate lubrication to engine components, particularly during start-up and under high-temperature conditions.

As the oil fails to create a sufficient film between moving parts, the pressure within the oil system can drop. This is because low viscosity oil will not maintain the necessary pressure required for optimal engine operation, leading to readings lower than normal on the oil pressure gauge. In a well-functioning engine, the oil needs to effectively fill the oil passages and maintain a proper pressure throughout the system to ensure that all components are adequately lubricated.

Therefore, consistently low oil pressure readings when using low-viscosity oil can indicate that the oil is not performing effectively, which may lead to increased wear and damage to engine parts if not addressed appropriately.
