• Safe to use with every fill-up if desired

Maximum Concentration PEA Detergent:

Red Line SI-1 contains the maximum concentration of PEA (polyetheramine) detergent, the most effective cleaning agent for fuel systems. PEA is superior to other detergents because it cleans at higher temperatures, making it ideal for cleaning combustion chambers and intake valves where temperatures are extreme. The high concentration ensures maximum cleaning power in a single treatment.

GDI Engine Carbon Buildup Solution:

Gasoline Direct Injection (GDI) engines are prone to carbon buildup on intake valves because fuel doesn't wash over the valves like in port injection engines. This carbon buildup reduces airflow, causes rough idle, and decreases performance. SI-1's advanced formula is specifically designed to address GDI carbon issues, cleaning intake valves and preventing future buildup.

Restores Lost Horsepower and Fuel Economy:

Dirty fuel injectors spray irregular fuel patterns, causing poor combustion and reduced power. Carbon deposits in combustion chambers increase compression ratio and cause pre-ignition. SI-1 cleans both issues, restoring proper fuel delivery and combustion. The result is restored horsepower, improved throttle response, and better fuel economy.

Reduces Octane Requirement:

Carbon deposits in combustion chambers act as hot spots that cause pre-ignition and knock, requiring higher octane fuel. SI-1 removes these deposits, reducing octane requirement by up to 2 points. This means you can run lower octane fuel safely, or gain additional performance margin with your current fuel.

Track Safe Formula:

Unlike some fuel system cleaners that can damage catalytic converters or oxygen sensors, SI-1 is completely safe for all emissions equipment. The formula is track-tested and approved for racing applications where catalytic converters are often removed, but it's equally safe for street cars with full emissions equipment.

Why Red Line SI-1?

Red Line has been manufacturing premium synthetic lubricants and fuel additives for over 40 years. Their products are trusted by professional race teams and enthusiasts worldwide for proven performance and quality. SI-1 is formulated by chemists who understand engine performance and fuel system requirements.

Preventative Maintenance:

Regular use of SI-1 prevents carbon buildup before it becomes a problem. Using SI-1 every 3,000-5,000 miles keeps fuel injectors clean, prevents intake valve deposits, and maintains optimal combustion chamber conditions. This preventative approach is more effective and less expensive than dealing with severe carbon buildup.

Usage Tips:

• Add to fuel tank before filling with gasoline
• One bottle treats up to 20 gallons
• For best results, use with nearly empty tank
• Drive normally after treatment - no special procedures required
• Use every 3,000-5,000 miles for preventative maintenance
• For severe deposits, use in 2-3 consecutive tanks

Perfect For:

• GDI engines experiencing carbon buildup
• Turbocharged engines requiring clean injectors
• High-performance engines needing maximum power
• Track cars requiring reliable fuel delivery
• Daily drivers seeking improved fuel economy
• Preventative maintenance on any gasoline engine

Perfect For: All gasoline engines seeking professional-grade fuel system cleaning with Red Line SI-1 featuring maximum PEA concentration for GDI carbon removal and performance restoration.

Pro Tip: GDI engines benefit most from regular SI-1 use - prevents carbon buildup on intake valves that reduces performance.

15oz Bottle: Treats up to 20 gallons. Safe for catalytic converters and oxygen sensors.
