Drivers should always be mindful of what lights come on their dashboard. Among these, one light demands immediate attention due to it signifying a serious problem that could result in extensive and costly damage. The oil warning light, depicted by an old-fashioned oil can icon, is a sign of trouble within the vehicle’s oil system.

The oil system is essential for lubricating the engine and ensuring all mechanical parts function seamlessly. A malfunction in this system can cause rapid wear and tear, leading to catastrophic engine failure.

Annex 6 of the Highway Code notes the importance of any warnings that appear on the vehicle’s instrument panel. It advises: “Make sure that you understand the meaning of all warning displays on the vehicle instrument panel. Do not ignore warning signs, they could indicate a dangerous fault developing.”

What to do if your oil warning light comes on

Should the oil warning light activate while driving, it is critical to find a safe place to pull over and stop as soon as possible to prevent engine damage. After stopping, give the engine at least 10 minutes to cool down before checking the oil level with a dipstick, bearing in mind that hotter conditions may necessitate a longer wait before the engine is cool enough.

If you discover that the oil level is insufficient, you can top it up until it reaches the appropriate mark. Once completed, start your engine and observe if the oil light reappears.

However, if the oil tank is adequately filled, it is advisable to cease driving immediately and arrange for the vehicle to be transported to a garage for a thorough inspection and necessary repairs.

The cost of replacing an engine

Should your engine sustain such severe damage that it necessitates a full replacement, this could set you back thousands of pounds, depending on the car’s age and model. If you’re seeking a quote from a mechanic or garage to figure out the cost of replacing your engine, you can identify the specific engine type using the vehicle identification number – a unique 17-digit code assigned to your vehicle.

This code is typically located as a stamp on the left-hand corner of the windscreen, on the vehicle’s chassis, on the driver-side door, or within the engine bay.
