Chevron Techron Concentrate Plus fuel system cleaner — 12 oz. bottle, Pack of 6, PEA concentrated formula

Chevron Techron Concentrate Plus is a concentrated fuel-system cleaner that uses patented PEA chemistry to remove deposits from injectors, intake valves and combustion chambers, helping restore performance and fuel economy.

Techron Concentrate Plus is a concentrated, professional-grade fuel additive designed for periodic use in gasoline engines, including ethanol blends and flex fuels such as E85. Formulated with Chevron’s proprietary polyether amine (PEA) technology, this product targets carbon and varnish buildup that accumulates over time and impairs throttle response, idle smoothness and mileage. Sold as a 12 oz. bottle in a pack of six, it treats a full tank of fuel when used as directed and is suitable for cars, light trucks and many small-engine applications.

How does Techron Concentrate Plus clean the fuel system?

Techron’s PEA-based formula lifts and dissolves stubborn carbon deposits that form on fuel injectors, intake valves and inside combustion chambers. These deposits affect spray patterns, airflow and combustion efficiency, so removing them helps restore original engine behavior without disassembly.

• Breaks down gum, varnish and carbon residues on fuel system components
• Works in injectors, carburetors, intake ports and chambers
• Concentrated dose treats a full fuel tank for thorough cleaning

What improvements can I expect after using it?

Users typically notice smoother idling, reduced hesitation during acceleration and more consistent throttle response after treatment. While individual results vary, restoring cleaner fuel flow and combustion can also recover some lost fuel economy and improve cold-start behavior.

• Reduces rough idle, engine surge and hesitation
• Helps restore lost power, acceleration and fuel efficiency
• Improves cold-start performance and long-term fuel stability

How and when should I use this product?

For most passenger vehicles and light trucks, add one 12 oz. bottle to a full tank of gasoline every 3,000 miles or at your next oil change. Other gasoline engines — motorcycles, boats, ATVs, lawn equipment — can be treated as needed to address performance issues or before storage for fuel stabilization.

• Use one bottle per full tank for routine maintenance every 3,000 miles
• Safe for ethanol-containing fuels, including E85 and flex-fuel vehicles
• Also recommended before storing equipment to improve fuel stability up to a year

Is Techron Concentrate Plus compatible with my vehicle and are there any precautions?

Techron Concentrate Plus is formulated to be compatible with modern gasoline engines and is recommended by various automakers. Always follow your vehicle manufacturer’s service recommendations and the directions on the bottle. Avoid overuse, and do not exceed the recommended concentrate per tank.

• Safe for automobiles, trucks and most gasoline-powered small engines
• Follow owner’s manual guidance and product dosing instructions
• Do not mix with incompatible additives or exceed the recommended dose

Who is this for? Chevron Techron Concentrate Plus is aimed at motorists and equipment owners who want a concentrated, professional-level cleaner to tackle clogged injectors, sticky intake valves and combustion chamber deposits. It’s ideal for drivers seeking routine preventative maintenance, users restoring throttle response or fuel economy, and owners of ethanol-fuel vehicles who need a cleaner proven to work with flex fuels and E85.
