Engine Oil Recommendation
We recommend the use of INDIAN MOTORYCLE 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
