How to Choose Oil For a 150cc Scooter

Engine oil in a scooter is very much like blood in the human body; hence you need to be cautious of what you’re putting into it, or it can seriously disrupt its performance. A comprehensive catalog of functionality involving lubrication, cooling, engine protection, efficiency enhancement, and friction reduction makes it imperative to select the best of the best. It’s a small price to pay in the long run.

Here are some factors to help you choose the right oil:

Synthetic Blend/Fully Synthetic Oils

Personally, we think synthetic blend or fully synthetic engine oils prove to be the best because they reduce internal friction and foster a smooth movement of engine parts as compared to mineral oils.


The next thing you need to be on the lookout for is viscosity. Low viscosity oils flow freely while high viscosity oils flow comparatively slower. As mentioned earlier, 0W-40 fully synthetic oils substantiate an engine’s peak performance. You might want to opt for engine oil that is relatively higher viscosity once your scooter has aged.

0W-40 Oil Grade

Oil grade enlightens you on the perfect viscosity for effective lubrication in a particular temperature range. For example, for 10W-30, 10 shows low-temperature viscosity, and 30 indicates high-temperature viscosity. 

In the winters or if you live in an extremely cold area, it’s ideal to choose one that has a low ‘W,’ indicating a low-temperature winter rating. In the summers, you might want to use one with a higher viscosity because it sticks to the engine’s internal parts, providing lubrication in higher temperatures.

Riding Style

This is another factor to account for as motorcycle oil varies according to it. For performance enthusiasts, we would recommend buying synthetic motor oils. On the contrary, if you’re a calm driver, mineral oil would be a perfect choice; it’s usually pumped into brand new scooters.

Compliance Standards 

Lastly, always look out for compliance standards and standard marks to ensure the high quality of the engine oil. These include SAE, JASO, or API marks on the bottles.

Review of the Best Oil For 150cc Scooters

Moreover, Castrol Power 1 comes with tri-zone technology, which ensures all-around protection of the gearbox, clutch, and engine. It is also capable of changing viscosity under mechanical stress, which helps it cope with extreme temperatures better.

If you love racing and crave for the thrill, then Castrol is the oil for you. Lastly, it fulfills all the requirements of API and JASO standards.

Bottom Line

According to users, there’s no superior bike specific oil for an ‘almost’ eradication of clutch disc sticking. We’d say this is an all-rounder perfect for consumers owning four-stroke engine scooters. Overall, Castrol Power oil remains one of the top products in the market for the current year.

Cautious Considerations to Keep in Mind

The oil you should ideally use is mentioned on the user’s manual of your bike, and it would be best to follow the specified guidelines. However, in other cases, not all types of oils work the same way. For instance, a four-stroke engine oil might not work for a two-stroke engine.

Similarly, there are other considerations to remember, including:

Synthetic Oil is Unnecessary, Provided the Scooter is New

Synthetic oil on paper seems better as it is tailored for engines alone, having higher heat tolerance, but it might not be necessary for all scooters, especially newer ones. Thus, spending more won’t mean getting optimal performance.

Mixing Additional Additives to Freshly Changed Oil is Useless

Adding or mixing additional additives is not recommended when you’ve changed your oil, as synthetic blends already have additives; adding more will not offer any further benefit.

Driving Conditions Should Be Taken Into Consideration During Oil Maintenance

Driving conditions such as temperature and the types of pavement will have different effects on the bike and will require different oil maintenance care. For instance, off-road driving might require higher grade frequent oil changes comparatively.

The Ideal Viscosity For Oil is Directly Related to the Age of the Scooter

The age of the scooter and, more specifically, its engine is of high relevance. For more mileage, it may need high-mileage oil with a higher viscosity.

This is because it might have more qualities better suited for the wear and tear the engine has gone through.

Noise and Clutch Slippage

Noise and clutch slippage is another factor to be considered into account, as mentioned before. Also, changing the oil filter should not be overlooked.

How to Change the Oil in a 150cc Scooter

Changing the oil in your own scooter is not that difficult. If your mechanic is unavailable or if you’re planning on doing it yourself regardless, here is how to go about it.

  1. Firstly, locate where the gearbox oil of your scooter is. In most cases, it will be situated below on the back of the engine. Have some equipment such as tools (10mm socket wrench), gloves, cleaning cloth, and containers to catch the leaking oil and the new oil in hand before beginning.
  2. Then, unscrew both of the bolts with a 10mm socket wrench, starting with the upper one first. It will start leaking the oil as soon as you unscrew the bolt.
  3. You will need to wait for it to drain all the oil from the upper and then the lower part, leaving gravity to do the work for you.
  4. After the oil is drained completely, screw back the bottom bolt and squeeze in the new oil through a nozzle into the upper bolt hole until it starts to overflow.
  5. Then, let it drain until only a few drops are left dripping from the top bolt hole and screw the upper bolt back as well.

Keep in mind not to apply too much force when tightening the bolt back as this may cause the bolt or the threads to break. It is best to watch the video below as it shows a detailed guide, which is much easier to grasp.


To recapitulate, we see how different types of oils interact with different kinds of engines. It is quintessential that you know the model or make of your own scooter before beginning, as there are many options to choose from. Once you know the specifications, you will have the tools to trickle down what fits the bill for your needs.

From a synthetic blend of a high-tech engine to a high viscosity thicker oil for an older working engine, we discussed what is best for a four-stroke engine and what is best for a two-stroke engine. Make sure you take into account all factors before making your pick!

What Oil Does a Scooter Take?

Again, we recommend users check their owner’s manual for the recommended oil type for their particular model, but generally speaking, for a four-stroke scooter, it’s ideal to use 10W-30 or 15W-40 engine oil.

Two-stroke scooters, however, need a slightly different oil designed for their particular configuration. Since two-cycle scooters use a phenomenon known as a total loss lubrication system whereby the oil is mixed with the fuel, it’s crucial to use an oil specially designed for that purpose.

Can I Use Car Oil in my Scooter?

Absolutely not! Choosing an oil not specifically designed for scooters as labeled on the packaging can cause irreparable damage. Car and scooter oils are on completely different wavelengths than one another.

Car oils contain friction modifiers designed to reduce friction between moving parts of a car, while scooter oils require the same oil for their engines and gearbox. Hence the two cannot be interchanged.
