Motorcycle engine oil ingredients
There are additional challenges that a lubricating oil must overcome in a motorcycle, including a low volume of oil, high temperatures, high specific power, high average RPM, and so high component stresses. As well as these challenges, as cities across the world look to reduce air pollution, motorcycles are coming under increasing scrutiny, with new regulations adopted to curb emissions.

Friction modifiers for manual transmission motorcycles
In passenger cars, low viscosity engine oils are used to provide low drag to improve fuel economy and reduce emissions. Low viscosity oils have poorer film forming properties and so in passenger cars, friction modifiers are used to reduce metal-on-metal friction and wear.
In a motorcycle, lower viscosity oils are not generally used because the oil must also lubricate the transmission. Transmissions need thicker, more viscous oils with good film forming properties in order to limit gear wear and increase durability.
The “feel” of bike and how the clutch engages is also very important. In the clutch, a high friction environment is desirable to prevent slippage and poor feel. The same engine oil is used to lubricate the clutch and so friction modifiers can negatively affect the clutch friction in a motorcycle, by reducing it too much and causing the clutch to slip. Therefore, friction modifiers are not generally used in wet-clutch motorbikes.
There is a need for friction modifiers that reduce engine drag and increase fuel economy even in a high viscosity engine oil.

Engine test data summary
- We tested fuel consumption in a 110cc Honda Wave motorcycle with wet clutch on a rolling road
- The 0W30 MA2 engine oil was top treated with Perfad 3971
- A reduction in fuel consumption of 0.23% was measured
- We demonstrate an increase in power and torque with Perfad 3570 and 3571 in a 150cc Japanese OEM motorcycle with wet clutch
- The 5W40 MA racing oil was top-treated with Perfad 3570 and 3571 at 1% and 0.5% w/w.
Testing solubility of Perfad 3500
In rare cases the product may not be completely soluble, however this can usually be solved by re-formulating the lubricant.
Perfad 3570 is a polymeric organic friction modifier particularly suited for use in four stroke motorcycle engine oils.
Perfad 3571 is a saturated fatty alcohol friction modifier particularly suited for use in four stroke motorcycle engine oils.
Perfad 3575 is a polymeric organic friction modifier particularly suited for use in four stroke motorcycle engine oils.
Perfad 3576 is a polymeric organic friction modifier particularly suited for use in four stroke motorcycle engine oils.
