Regularly checking the level of your motorcycle oil is essential for maintaining its performance, longevity, and overall health.

The Right Way To Check Engine Oil Level On A Motorcycle

Before diving into the specific methods for checking the oil level on a motorcycle, it’s important to understand the general process and necessary conditions for accurate readings. Keep in mind the following steps:

  1. Park your motorcycle on level ground: This ensures that the oil settles evenly within the engine for an accurate reading.
  2. Make sure your bike is upright: Whether you’re using a center stand, paddock stand, or holding the bike upright, this step is crucial for getting the correct reading.
  3. Allow the engine to cool down or wait for at least 15 minutes: This allows the oil to drain back into the crankcase for an accurate measurement.

Once you’ve completed these steps, you can proceed with checking the oil level using either a sight glass or a dipstick, depending on your motorcycle’s design.

Motorcycles With A Sight Glass

A sight glass is a small window on the side of the engine crankcase that allows you to visually check the oil level. There are typically two levels, a high and low mark.

To check the oil level using a sight glass, follow these steps:

  1. Position your motorcycle according to the steps mentioned earlier.
  2. Locate the sight glass on the side of the engine crankcase.
  3. Look for the two marks on the case surrounding the window – these indicate the minimum and maximum oil levels.
  4. Ensure that the oil level reflected is between the two marks.

If the oil level is below the minimum mark, add oil until it reaches the appropriate level. If it’s above the maximum mark, you’ll need to drain some oil to avoid overfilling.

Motorcycles With A Dipstick

A dipstick is a long rod with markings that indicate the minimum and maximum oil levels (if you didn’t know). In my experience riding them, this is most commonly found on Triumph Motorcycles, but can appear on other brands of bikes as well.

To check the oil level using a dipstick, follow these steps:

  1. Position your motorcycle according to the steps mentioned earlier.
  2. Locate and remove the dipstick from the engine crankcase.
  3. Wipe the dipstick clean with a cloth or paper towel.
  4. Reinsert the dipstick into the engine, making sure it makes contact with the filler plug’s threads (do not screw it in all the way).
  5. Remove the dipstick and check the engine oil level against the markings.

Add or drain oil as needed to maintain the appropriate engine oil level.

Different motorcycles have different requirements for checking the engine oil level, some may suggest checking the engine oil levels in the bike’s natural position whereas others may suggest you put it upright on a flat surface.

In general, it’s best to check the engine oil level with the bike in an upright position to get the most accurate reading. If your motorcycle has a center stand or paddock stand, you can use it to keep the bike upright while checking the oil level. However, always refer to your owner’s manual for specific instructions regarding your bike model.

How To Know When Your Motorcycle Is Low On Engine Oil

Apart from visually checking thebike’s engine oil level through a sight glass or dipstick, there are other signs that your motorcycle may have a low engine oil level:

  1. An illuminated oil warning light on the instrument panel.
  2. Unusual engine noises and premature engine wear such as knocking or ticking sounds.
  3. Decreased performance or poor fuel efficiency.
  4. Excessive engine heat or smoke from the exhaust.

If your motorcycle exhibits any of these symptoms, it’s crucial to check the oil level and address any issues as soon as possible.

How Does An Oil Pressure Gauge Work?

An oil pressure gauge works to measure the oil pressure inside the crankcase of the motorcycle. Naturally, when there is enough oil in the crankcase the oil pressure gauge is higher; which is why it works to tell you that the oil level is dropping because the oil pressure is dropping along with it.
