Quick Answer
Bajaj Pulsar engine oil varies by model: 10W-30 JASO MA2 for Pulsar 125 and 150; 10W-40 JASO MA2 for Pulsar 180, NS200, and RS200; 20W-40 JASO MA2 for Pulsar 220F; and 10W-50 JASO MA2 for Dominar 400. Using a single grade across the full Pulsar range is a common and potentially damaging mistake — each engine platform has a different thermal output and bearing design.
Bajaj Pulsar Engine Oil: Why Different Models Need Different Grades
The Bajaj Pulsar range spans from the entry-level 125cc commuter to the performance-oriented 400cc Dominar — a spread of engine outputs from 11 PS to 40 PS. Each platform has a distinct thermal output, bearing design, and cooling system. This means there is no single engine oil specification that fits every Pulsar model: a 10W-30 ideal for the Pulsar 125 would be insufficient for the Dominar 400's forced-oil-cooled engine under highway load. Using the correct viscosity grade matched to your specific Pulsar model is essential for protecting internal engine components and maximising service life in Indian conditions.

| Model | Engine | OEM Grade | Carbo Oil Recommendation |
|---|---|---|---|
| Pulsar 125 (NS/Split) | 124.4cc BS6 | 10W-30 JASO MA2 | 01 GT 10W30 API SP |
| Pulsar 150 / 150 Twin Disc | 149.5cc BS6 | 10W-30 JASO MA2 | 01 GT 10W30 or 01 RS 10W30 API SP |
| Pulsar 180 / 180F | 178.6cc BS6 | 10W-40 JASO MA2 | 01 RS 10W40 API SP |
| Pulsar NS200 / AS200 | 199.5cc BS6 liquid-cooled | 10W-40 JASO MA2 | 01 RS 10W40 API SP |
| Pulsar RS200 | 199.5cc triple spark | 10W-40 JASO MA2 | 01 RS 10W40 API SP |
| Pulsar 220F | 220cc oil-cooled | 20W-40 JASO MA2 | SUPER-FS 10W40 API SN |
| Dominar 400 | 373.3cc liquid-cooled | 10W-50 JASO MA2 | 01 RS 15W50 API SP |
Why the Pulsar 220F and Dominar 400 Have Different Oil Specs
The Pulsar 220F uses an older oil-cooled 220cc engine platform where Bajaj specifies 20W-40 JASO MA2 — a thicker cold-start viscosity grade that suits the wider manufacturing tolerances of this older engine design. The 220F is largely a pre-BS6 era platform; if you own a BS6-compliant variant, confirm with your dealer whether 10W-40 is also accepted. Carbo Oil's SUPER-FS 10W-40 API SN is a modern semi-synthetic alternative that meets or exceeds the 220F's requirements with better cold-start flow. The Dominar 400 is a different matter entirely: Bajaj's official specification is 10W-50 (higher operating viscosity than standard 10W-40) to handle the 40 PS output of the 373cc liquid-cooled engine. Carbo Oil's 01 RS 15W50 is the closest available product with the 50-grade operating viscosity the Dominar needs.
Slipper Clutch and Oil Compatibility in NS200, RS200
The Pulsar NS200 and RS200 feature slipper clutch mechanisms. Contrary to a common misconception, slipper clutch motorcycles still use a wet clutch system — JASO MA2 certification is still required. The slipper clutch uses asymmetric cam ramps to disengage partial clutch pressure during hard downshifts, preventing rear wheel lockup. The oil must still maintain adequate static and dynamic friction for normal clutch engagement while allowing the slipper mechanism to function. Carbo Oil's API SP JASO MA2 formulation provides this balance without the friction modifiers that would interfere with clutch operation.
