Frequently asked questions

For most motorcycles using Bagani Amihan Tempest 4T, we recommend an oil change every 2,000–3,000 km under normal riding conditions, or every 1,500 km for heavy-duty use and long daily commutes.

The Amihan Tempest 4T (20W-50) is recommended for motorcycles and big bikes. For scooters, we recommend the Amihan Gale (10W-40 JASO MB) for better compatibility with CVT-equipped engines.

Bagani oils are available at authorized motorcycle shops, auto parts stores, and online marketplaces across the Philippines. Contact us at info@baganioil.com to find the nearest dealer in your area.

JASO MA-2 is a Japanese Automotive Standards Organization certification for 4-stroke motorcycle oils. It ensures the oil provides excellent wet clutch friction performance, meaning your clutch will engage and disengage smoothly without slipping.

While mixing oils won't immediately damage your engine, we recommend using only Bagani oils for best performance. Mixing different brands can dilute the additive packages and reduce the overall protection level. When switching, perform a full oil change.
