The Yamaha Blaster sports a 200cc air-cooled, two-stroke engine with a reputation for power and simplicity. It requires premixed fuel, meaning oil is mixed with gasoline to lubricate internal engine parts. Since two-stroke engines don’t have an oil reservoir like four-strokes, the quality of premix oil is critical.

What Type of Engine Oil Does a Yamaha Blaster Use?
Two-Stroke vs Four-Stroke Oils
Your Yamaha Blaster uses two-stroke engine oil, also known as 2T oil. It’s specifically designed to burn cleanly with the fuel and lubricate without leaving excessive residue.
Recommended Viscosity Grades
While viscosity isn’t as variable in 2-stroke oils as it is in 4-stroke oils, you should stick with manufacturer-recommended oils like Yamalube 2R, which are optimized for high-revving engines.

Benefits of Using High-Quality Engine Oil
Improved Engine Longevity
Premium oils reduce internal friction and wear, helping your engine last longer and resist damage under extreme conditions.
Better Fuel Efficiency
Efficient combustion thanks to quality oil reduces carbon deposits and improves fuel economy.
Enhanced Performance
Smooth, responsive power delivery and cooler engine temperatures are hallmarks of using the right oil.

How to Change Engine Oil in a Yamaha Blaster
Although the Blaster uses premix, it’s still important to clean or replace the oil mixture and perform general lubrication.
Tools and Supplies Needed
- Oil measuring cup
- Two-stroke engine oil
- Mixing can
- Fresh gasoline
- Spark plug wrench
- Funnel
Step-by-Step Process
- Drain Old Fuel: Empty the fuel tank completely.
- Prepare the Mix: Mix oil and gas in the correct ratio (Yamaha recommends 32:1).
- Refill Tank: Use a funnel to pour the premix back into the fuel tank.
- Check Spark Plug: Clean or replace to ensure efficient combustion.
- Test Run: Start and idle the engine for a few minutes.
Common Mistakes to Avoid
- Using four-stroke oil: Will cause buildup and can damage your engine.
- Incorrect mixing ratio: Can lead to overheating or smoking.
- Cheap, off-brand oil: Often contains poor-quality additives or too much ash.

FAQs
What kind of oil do I put in my Yamaha?
The type of oil depends on the Yamaha model. For Yamaha two-stroke engines like the Yamaha Blaster, you should use high-quality 2-stroke engine oil, preferably a synthetic or semi-synthetic premix oil designed for off-road or ATV engines (e.g., Yamalube 2R, Maxima Castor 927).
For four-stroke Yamaha motorcycles, use 4-stroke motorcycle oil that meets JASO MA/MA2 and API SG or higher specifications. A common recommendation for many Yamaha bikes is 10W-40 engine oil.
Can I use 15W-40 engine oil for a bike?
Yes, 15W-40 engine oil can be used for some motorcycles, especially in warmer climates, if the oil meets motorcycle-specific standards like JASO MA/MA2. However, it’s more commonly used in diesel engines and heavy-duty applications. It’s not typically recommended for high-performance or small-displacement bikes unless specified by the manufacturer.
What engine is in a Yamaha Blaster?
The Yamaha Blaster is powered by a 195cc air-cooled, single-cylinder, 2-stroke engine with a reed valve induction system. It features a 6-speed manual transmission and uses premixed gasoline and 2-stroke oil instead of a separate oil injection system.
This engine is known for its torque, lightweight performance, and ease of maintenance.
Is gear oil the same as engine oil on a motorcycle?
No, gear oil and engine oil are not the same, although some motorcycles (especially those with wet clutches and integrated gearboxes) use the same oil for both engine and transmission.
- Gear oil (like 80W-90 or 75W-140) is thicker and designed specifically for transmission and differential components.
- Engine oil is formulated to handle combustion by-products and protect engine internals.
Two-stroke motorcycles like the Yamaha Blaster have separate gear oil and use premix oil for the engine, whereas four-stroke bikes often use shared oil for the engine and transmission.
What is the advantage of 20W-50 engine oil?
20W-50 engine oil is thicker than standard oils like 10W-40, and offers:
- Better high-temperature protection: Ideal for hot climates or air-cooled engines.
- Improved film strength: Provides extra cushioning and protection under load.
- Slower breakdown: Helps in older engines or motorcycles with high mileage that may burn or leak oil.
However, it may not be suitable for cold weather starts or engines designed for thinner oils.
What is the difference between 10W-40 and 20W-50 motorcycle oil?
| Feature | 10W-40 | 20W-50 |
|---|---|---|
| Viscosity (Cold) | Better in colder temps | Thicker; slower to flow in cold |
| Viscosity (Hot) | Suitable for moderate temps | More resistant to thinning in heat |
| Engine Type | Ideal for modern engines | Better for older, high-mileage engines |
| Climate Suitability | All-season (mild to moderate) | Hot climates or summer riding |
| Fuel Economy | Slightly better | Slightly worse due to thickness |
Final words
Your Yamaha Blaster deserves top-tier care, and that starts with the right engine oil for Yamaha Blaster. Stick with trusted products like Yamalube, Maxima, and Motul. Follow proper premixing procedures, and you’ll enjoy the full power and reliability of your Blaster every time you ride.
