Engine Oil Recommendation

We recommend the use of INDIAN MOTORCYCLE Premium Synthetic Blend 20W-40 Engine Oil for your motorcycle. This oil is formulated with synthetic-based oil and premium engine additive which have physical properties that meet API SM and ILSAC GF-4 specifications.
Do not blend oil additives with engine oil.
If oil must be added in an emergency and the recommended oil is not available, choose only a high-quality 20W-40 motorcycle oil. Change back to the recommended oil at the first opportunity.
NOTICE
Use of non-recommended lubricants can result in engine damage. Damage resulting from the use of non-recommended lubricants is not covered by warranty.
