Like any other vehicle, your motorcycle requires a basic level of maintenance to keep it performing at its best and ensure your safety. One of the most important aspects is the motorbike engine oil. Depending on the type of bike and how it is used, it must be frequently replaced. But what type of oil do you need? And should you check the oil when the engine is hot or cold?

With various engine types and oils, many owners are faced with a confusing array of information and products and don't know where to start. So here at OneHowTo we have put together a quick and easy guide to explain step-by-step how to check the oil level on a 4-stroke motorcycle engine.

Steps to follow:

1

For our bike to circulate properly and effectively, it is important to maintain a good level of oil. With a 4-stroke engine, you should check the oil level and top it up appropriately every 1,000 km and just before a long journey.

If you tend to drive on unstable ground or go offroad, or live in a place with a hotter climate, you should check the oil more frequently than this. Regular checks can prevent engine wear and ensure optimal performance.

So when is the best time to check the oil level for a motorbike engine? Should you check the oil when the engine is warm or cold? To get the most accurate result, it is recommended to go out for a quick spin to warm the engine and get the oil circulating. Once you get home or wherever you are going to do the review, you should let the bike stand for about 15 minutes to allow the oil to drain and return to its natural position. This method ensures that the oil has settled, providing a more accurate reading.

While many people recommend measuring motorcycle oil cold, this method is considered more effective by some mechanics, as a warmed engine can give a truer indication of oil levels and condition.

After the 15 minutes, with the bike in an upright position without being supported on the stand, take out the dipstick and wipe it clean. Replace it but without screwing it in (very important) to measure the current level of oil. This step ensures that you are getting an accurate reading, as screwing in the dipstick might lead to incorrect measurements.

There are different types of rods, but all will always have an indicator with two stripes that indicate clearly the minimum and maximum oil level your bike engine needs. When removing the rod, you will see the current level of oil. If it is correct, screw it back in and you are good to go. If the oil is too low, you must top up or change the oil and fill to the desired level. Keeping the oil within these limits is crucial for engine health, as insufficient oil can lead to overheating and excessive friction.

5

It is important to note that you should always use the same type of oil to replenish the bike's oil levels. So once you do an oil change on your bike, be sure to purchase one or several bottles of the same brand to take home for subsequent top-ups. Consistency in oil type is essential to ensure that your engine operates smoothly and reduces the risk of compatibility issues.

Are you sure about that? If I check the oil with my bike horizontal, the oil will drain out.
