Questions & Answers
Is this oil safe for motorcycles with a wet clutch?
Yes. This oil meets the JASO MA2 specification, which is the highest standard for wet-clutch compatibility, ensuring smooth engagement and preventing slippage.
How do I know if it is compatible?
We recommend checking your owner's manual for the recommended viscosity. If your manual specifies 20W-40 and requires an API SL/SM/SN or JASO MA/MA2 standard, this oil is a guaranteed fit.
Can I use this in an air-cooled engine?
Absolutely. The 20W40 grade is specifically popular for air-cooled engines (such as Yamaha Virago or Victory models) as it provides a thicker oil film at high operating temperatures compared to 10W40.
Note: 4Drive lubricants are manufactured to meet or exceed OEM performance requirements. Always consult your vehicle manual for specific oil change intervals.
