Last Updated on September 30, 2025 by foysal islam

As the proud owner of a 150cc scooter, you know the thrill of zipping through city streets, weaving through traffic, and enjoying the wind in your hair. But to keep your trusty two-wheeler running at its best, regular maintenance is a must – and that includes changing the oil. Don’t worry, it’s not as daunting as it may seem! In this comprehensive guide, I’ll walk you through the step-by-step process of changing the oil on your 150cc scooter, so you can keep your ride in top-notch condition.

Understanding the Importance of Regular Oil Changes

Oil is the lifeblood of your scooter’s engine, and it plays a crucial role in keeping all the moving parts lubricated and functioning smoothly. Over time, the oil breaks down, becoming thinner and less effective at its job. Changing the oil on a regular basis is essential to prevent wear and tear on your engine, ensuring it runs efficiently and has a longer lifespan.

Neglecting oil changes can lead to a host of problems, including increased fuel consumption, decreased power and acceleration, and even engine failure down the line. That’s why it’s recommended to change the oil on your 150cc scooter every 3,000 to 4,000 miles, or at least once a year, depending on your usage and the manufacturer’s recommendations.

Gathering the Necessary Supplies

Before you get started, make sure you have all the supplies you’ll need to complete the oil change. Here’s what you’ll want to gather:

• New engine oil – Check your owner’s manual for the recommended oil type and quantity, which is typically around 0.8 to 1 liter for a 150cc scooter.
• Oil filter – This may or may not be included in your scooter’s maintenance kit, so double-check and purchase one if needed.
• Oil drain pan – This will catch the old oil as it drains from the engine.
• Wrenches and tools – You’ll need a set of metric wrenches, pliers, and a screwdriver or two to access the oil drain plug and filter.
• Rags or paper towels – For cleanup and to wipe down the engine after the oil change.

Preparing Your Scooter for the Oil Change

Before you dive in, it’s important to prepare your scooter properly. Start by parking your scooter on a level surface and applying the parking brake to keep it steady. If your scooter has a centerstand, use that to prop it up; if not, you may need to use a small jack or motorcycle lift to get the rear wheel off the ground.

Next, locate the oil drain plug, which is typically located on the bottom of the engine or transmission case. Place the oil drain pan underneath to catch the old oil as it drains out.

Draining the Old Oil

Using the appropriate wrench, slowly loosen the oil drain plug by turning it counterclockwise. Be careful, as the oil may be hot, so take caution to avoid burns. Allow the oil to drain completely into the pan, which can take a few minutes.

Once the oil has fully drained, replace the drain plug by turning it clockwise until it’s snug, but don’t overtighten it.

Replacing the Oil Filter

Now it’s time to replace the oil filter. Locate the filter, which is usually accessible from the side or top of the engine. Use a filter wrench to loosen and remove the old filter, then apply a thin coat of new oil to the gasket of the new filter before screwing it on by hand until it’s secure.

Refilling with Fresh Oil

With the old oil drained and the new filter in place, it’s time to add the fresh oil. Consult your owner’s manual for the recommended oil type and quantity, and slowly pour the new oil into the designated fill port, typically located on the top or side of the engine.

Be sure to add the oil slowly and check the dipstick periodically to avoid overfilling. The total capacity for a 150cc scooter is usually around 0.8 to 1 liter.

Final Checks and Cleanup

Once you’ve added the new oil, replace the dipstick and start the engine, letting it run for a minute or two. This will help distribute the fresh oil throughout the engine.

Check the oil level again and top it up if necessary, making sure it’s within the “full” range on the dipstick. Finally, wipe down any spills or drips with a clean rag and dispose of the old oil and filter properly.

Conclusion

Changing the oil on your 150cc scooter may seem like a daunting task, but with the right tools and a little bit of know-how, it’s a straightforward maintenance task that you can easily tackle yourself. By following this step-by-step guide, you’ll be able to keep your scooter running smoothly and extend the life of your engine. Remember to change the oil regularly, and enjoy the peace of mind that comes with knowing your ride is well-maintained.
