As an avid motorcyclist, I can confidently say that Harley-Davidson motorcycles, known for their robust oil systems and iconic design, are in a class of their own. Known for their iconic design and unmatched performance, Harley motorcycles are a symbol of freedom and adventure. However, like any other piece of machinery, they too can exhibit certain quirks. One such quirk that has puzzled many Harley-Davidson owners is the mystery of the Harley oil light being on before starting. In this blog, we will delve deep into this mystery and help you understand why your Harley oil light may be on before starting your ride.
Harley motorcycles have a rich history dating back to the early 20th century. Over the years, these machines have evolved, integrating the latest technologies without compromising their classic appeal. As an owner, it is essential to familiarize yourself with the various components and systems of your Harley to ensure a smooth and enjoyable ride.
One critical system that requires your attention is the oil system. The oil light on your Harley-Davidson’s dashboard is a crucial indicator of the oil system’s health, including oil pressure and oil level. It may seem like a minor detail, but understanding this light and its implications can go a long way in maintaining your Harley in top condition.
Understanding the Harley Oil Light (When Does It Come On and Why?)
The Harley oil light is a warning indicator that lights up when there is an issue with the oil system of your motorcycle. It may illuminate for various reasons, including low oil level or low oil pressure, the most common issues. However, what confuses many Harley riders is when the oil light is on before starting the bike.
When you turn the ignition key of your Harley but do not start the engine, you will notice that the oil light is on. This is normal. The light illuminates because the oil pressure sensor has not detected any oil pressure. Once you start the engine, the oil pump begins to circulate oil, and the oil pressure builds up. The oil light should then go out.

If the Harley oil light stays on even after starting the engine, it may indicate a problem with the oil pressure or oil level. It could be due to low oil level, a faulty oil pump, a clogged oil filter or oil lines, or even a malfunctioning oil pressure sensor.
Most Common Reasons Why Your Harley Oil Light Is On Before Starting
As mentioned earlier, the Harley oil light being on before starting the engine is normal. However, if it stays on after the engine has started, then there are some common reasons you should look into.
The most frequent causes are a low oil level or a malfunctioning oil pressure switch. If you haven’t checked your Harley’s oil level in a while, it might have gone down due to normal consumption or a leak. Insufficient oil can lead to inadequate lubrication and excessive engine wear.
Another common reason for the Harley oil light issue is a faulty oil pump, affecting oil pressure. The oil pump is responsible for circulating oil throughout the engine. If it is not working correctly, it will fail to maintain the required oil pressure, and the oil light will stay on.
A clogged oil filter, oil lines, or an issue with the oil drain can also result in low oil pressure. Over time, dirt and debris can accumulate in the oil filter or oil lines, restricting the flow of oil. This can prevent the oil from reaching critical engine components, leading to increased friction and heat generation.
Finally, a malfunctioning oil pressure sensor can falsely trigger the oil light. The sensor measures the oil pressure in the engine and sends this information to the bike’s computer. If the sensor is not working correctly, it can give an incorrect reading, causing the oil light to stay on even when there is no issue with the oil pressure.

What To Do When Your Harley Oil Light Is On
If your Harley oil light is on after starting the engine, do not panic. First, check the oil level. If it is low, top it up with the recommended type of oil.
If the oil level is okay, check the oil filter and oil lines for any blockages. Replace the oil filter or check the oil pump if it is clogged, dirty, or malfunctioning.
If the oil light is still on, it could be due to a faulty oil pump or oil pressure sensor. In such cases, it is best to seek professional help as these components require specialized tools and expertise for diagnosis and repair.
It is worth noting that you should not ignore the oil light. Riding your Harley with low oil pressure can cause severe engine damage. And it would help if you’re aware of this: Harley Davidson Oil Capacity Revealed (All Engines)
Quick Explanation of A Harley’s Oil System
The oil system of a Harley is a critical component that ensures the smooth operation of the engine. It consists of the oil pump, oil filter, oil lines, oil pressure sensor, and the ignition switch.
The oil pump circulates the oil throughout the engine, providing lubrication to the moving parts. The oil filter removes any dirt or debris from the oil to prevent them from damaging the engine components. The oil lines transport the oil from the oil pump to various parts of the engine. The oil pressure sensor monitors the oil pressure in the engine and signals the oil light if the pressure drops below a specified level.
What You Should Know About Oil (Types, Pressure, Etc,.)
Different Harley models may require different types of oil, so consider the oil change frequency and type carefully, so always refer to your owner’s manual for the recommended oil type. Generally, mineral oils are suitable for older models, while synthetic oils are best for newer models.
Oil pressure is a critical parameter that indicates the efficiency of the oil system. Normal oil pressure for a Harley is between 10 to 20 psi at idle and 30 to 38 psi at high speeds. If the oil pressure is below these levels, it can lead to inadequate lubrication and potential engine damage.
General Maintenance Practices To Avoid Issues
Regular maintenance, including timely oil changes and oil filter replacements, is key to keeping your Harley-Davidson in top condition and avoiding issues like the oil light coming on. Check the oil level regularly and top it up if necessary. Change the oil and oil filter at the intervals specified in your owner’s manual.
Ensure that the oil lines are clean and free from blockages. Keep an eye out for any oil leaks and get them fixed promptly. Listen for any unusual noises from the engine, as they can be an early warning sign of problems.
When To Seek Professional Help: A Persistent Oil Light
If the oil light remains on despite your troubleshooting efforts, it is time to seek professional help. A persistent oil light can indicate a serious issue that requires the expertise of a professional mechanic.
Remember, ignoring the oil light can lead to catastrophic engine damage. So, do not delay in getting your Harley checked if the oil light is on.
Wrapping Things Up
Understanding the Harley oil light mystery is not as daunting as it might seem. With a basic understanding of the oil system and regular maintenance, you can ensure that your Harley stays in top-notch condition.
Remember, the oil light is not something to be ignored. It is a critical indicator of your Harley’s health. If it comes on, take the necessary steps to identify and fix the issue. If in doubt, always seek professional help. Happy riding!
