Red Line Synthetic Oil, Fluids and Additives

Shop Red Line synthetic motor oil, gear lubricants, transmission fluids, fuel-system treatments, cooling additives, and vehicle-service fluids by exact product specification and manufacturer part number.

Choose the Correct Red Line Fluid

Match the required viscosity, lubricant standard, fluid specification, container size, and service application before ordering. A vehicle may require different fluids for its engine, transmission, differential, transfer case, cooling system, and power steering system.

• Confirm the viscosity and manufacturer fluid specification
• Match the transmission or differential type and every limited-slip requirement
• Verify the quantity needed for a complete service
• Use only products approved for the intended system and operating conditions

Frequently Asked Questions

How do I select the correct Red Line motor oil?
Use the viscosity and performance specification required by the vehicle manufacturer, then account for climate, operating temperature, engine condition, and intended use.

Can I substitute one Red Line transmission or gear fluid for another?
Only when the selected product explicitly meets the required fluid specification. Manual transmissions, automatic transmissions, differentials, and transfer cases can require different friction and additive characteristics.

How much fluid should I order?
Check the manufacturer service capacity for the exact vehicle and component. Capacity can differ by drivetrain, cooler configuration, service procedure, and whether the system is completely dry.
