BRP OEM XPS 4T 5W-40 Synthetic Oil, 9779133, 9779492

This genuine BRP XPS oil (part number 9779133, superseded) is engineered for Sea-Doo and other powersports four-stroke engines, including turbocharged or supercharged setups. It’s a synthetic blend offering antiwear and anti-corrosion additives designed to extend component life and maintain performance in on-road, off-road, and personal watercraft (PWC) environments.

What makes this Sea-Doo oil suitable for high-performance powersports engines?

The formulation balances synthetic base stocks with targeted additives to resist wear while supporting extreme-duty operation. It’s specified for 4-stroke engines and works with transmissions where the manufacturer recommends this viscosity and type.

• 5W-40 viscosity for reliable cold starts and high-temperature protection.
• Antiwear agents reduce friction on critical moving parts.
• Corrosion inhibitors protect metal surfaces exposed to moisture and salt.
• Factory-original BRP part ensures compatibility with Sea-Doo systems.

How does this oil protect against rust and corrosion in marine or off-road use?

Specialized corrosion inhibitors are included to form a protective film on metal surfaces, reducing oxidation and galvanic action. That film helps preserve internal components when engines see moisture, salt spray, or muddy conditions.

• Formulated for PWC and off-road environments with higher moisture exposure.
• Reduces potential for surface pitting and rust on engine and transmission parts.
• Helps maintain seal and gasket condition by minimizing corrosive breakdown.

Can I use this oil in turbocharged or supercharged powersports engines?

Yes — the XPS 4T 5W-40 blend is suitable for boosted four-stroke engines where the manufacturer recommends a 5W-40 synthetic or synthetic blend. Its high-temperature stability helps protect bearings and pistons under increased loads.

• Stable viscosity under high heat common in forced-induction systems.
• Antiwear chemistry supports heavy-load operation and repeated RPM bursts.
• OEM-approved formulation reduces compatibility concerns with Sea-Doo components.

Which sizes and part numbers should I order for workshops or seasonal replacements?

This listing is for the OEM synthetic blend part (9779133), now superseded; a one-gallon format is also available under part number 9779493. Choose the volume that matches service intervals and storage needs.

• Current listing: part 9779133 (factory original, superseded).
