5 Recommended Racing Oils for Circuit Riding!

Engine oil is one of the most important consumables for motorcycles. For this reason, it is necessary to choose engine oil that suits your specific uses and purposes.
This is even more true for sports riding on a circuit, where the load on the engine is sure to increase. However, with racing oils now available from a wide variety of manufacturers and brands, it can be difficult to choose the right oil.
Therefore, this article introduces racing oils recommended for motorcycles used on circuits.

[1. How to Choose Engine Oil for Motorcycles Used on Circuits]

For motorcycles used on circuits, it is best to choose an engine oil with excellent acceleration performance. In addition, pay attention to high engine protection performance and low carbon buildup inside the combustion chamber.
Also, pay attention to the strength of the oil film. If the oil film is less likely to break even in summer when the oil temperature rises too high, and is resistant to thermal degradation, it can protect the pistons and cylinders from wear more effectively.

[2. What is the Difference Between Racing Oil and Regular Engine Oil?]

Racing engine oil, used in high-performance, high-output engines like those found in motorcycles used on circuits, has superior performance compared to general engine oil in three areas: "lubricity," "wear and seizure resistance," and "thermal and oxidation stability."
To achieve this performance, racing engine oil contains additives such as antioxidants and anti-wear agents, and is characterized by high viscosity-temperature characteristics that maintain viscosity even when the engine is operating at high speed and under high load.

Moty’s "FULLY SYNTHETIC OIL FOR FOUR STROKE M152"

Moty's "FULLY SYNTHETIC OIL FOR FOUR STROKE M152" is an oil developed with the concept of continuous long-term use, exhibiting excellent performance under all temperature and load conditions.
Among the series lineup, it supports high-torque, high-performance motorcycles. As a durable racing oil, it is recommended for riders who seek a smooth transmission feel.

Castrol "POWER1 RACING 4T"

Castrol "POWER1 RACING" is highly favored by riders who frequent circuits. It is considered ideal for high-performance 4-stroke motorcycles with medium to large displacement, offering excellent acceleration performance and high engine protection due to strong oil film formation.
It's also noteworthy for being 100% synthetic and relatively affordable. It is recommended for beginners who are new to circuit riding or racing oils.

WAKO’S "HYPER SPEC RR"

WAKO'S "HYPER SPEC RR" is a high-performance racing oil developed specifically for use in racing.
It possesses the performance to endure not only sprints but also endurance races, making it ideal for 4-stroke engines with wet clutches. Furthermore, it prevents thermal degradation in tuned engines and large-displacement models, allowing for stable oil pressure during circuit driving.
Additionally, by blending "30S" and "50S" from the series, you can achieve the optimal viscosity.

elf "HTX 909"

elf's "HTX 976+" is a 100% synthetic racing oil that has been improved and evolved from its predecessor, "HTX 976," an oil developed jointly by elf and motorcycle manufacturers for racing.
It is an SAE50 single-grade oil that can handle high rotational speeds of 18,000 rpm or more. With excellent lubricity and thermal stability, it protects the engine internals even at high temperatures and high revolutions.
This oil is also a designated oil for some road racing specific models, such as the "RS250R" and "TLR260."

MOTUL "300V FACTORY LINE ROAD RACING"

MOTUL "300V FACTORY LINE ROAD RACING" is a racing oil born from the experience and know-how of factory teams participating in competitions worldwide, featuring a base oil formulation called Ester Core Technology.
Compared to conventional oils, it increases horsepower by 1.3% and torque by 2.5%. At the same time, it maintains gear protection and wet clutch performance without compromising anti-wear properties. This oil delivers ideal performance for both on-road and off-road use.

[4. Summary]

The performance required for general engine oil and racing engine oil used on circuits differs. Of course, there is no problem using general engine oil for circuit driving, but you must be prepared for the load on the engine.
The oils introduced here are still just a small sample. Why not find your favorite oil and head to the circuit?
