Chevron Techron Fuel System Cleaner

Chevron Techron Complete Fuel System Cleaner

One-Tank Gasoline Fuel System Cleaner for Injectors, Intake Valves and Combustion Chambers

Chevron Techron Concentrate Plus Complete Fuel System Cleaner is a gasoline fuel additive designed to remove deposits throughout the fuel system in one tankful. Its detergent chemistry targets deposits on fuel injectors, carburetors, intake valves and combustion chambers that can contribute to lost performance, reduced fuel economy, hesitation and deposit-related knock or ping.

Techron Complete Fuel System Cleaner is formulated for modern and older gasoline engines, including port fuel injected, direct injected, carbureted and hybrid vehicles. It is also compatible with commercially available gasoline and ethanol blends, including E10 and E85.

Complete Fuel System Cleaning

Fuel deposits can form at several points throughout a gasoline engine's fuel and air-intake system.

Techron Complete Fuel System Cleaner is formulated to clean deposits from:

• Fuel injectors
• Carburetors
• Intake valves
• Combustion chambers
• Fuel gauge sending-unit components affected by sulfur contamination

Cleaning more than the injector itself is an important distinction between a complete fuel system cleaner and a basic injector-cleaning treatment.

Fuel Injector and Intake Valve Deposits

Injector deposits can disrupt fuel spray patterns and reduce the precision of fuel delivery.

Intake-valve and combustion-chamber deposits can also contribute to performance issues including:

• Rough operation
• Hesitation
• Reduced acceleration
• Deposit-related knock and ping
• Cold-start problems
• Lost fuel economy

Techron helps remove these deposits so the engine can recover performance that was lost because of fuel-system contamination.

It should not be expected to correct mechanical, ignition, compression or electronic problems unrelated to deposits.

Direct Injection and Modern Gasoline Engines

Chevron recommends Techron Complete Fuel System Cleaner for gasoline spark-ignition engines including:

• Port fuel injected engines
• Direct injected gasoline engines
• Carbureted engines
• Gasoline hybrid vehicles

This makes it suitable for many current passenger cars, SUVs and gasoline pickup trucks.

Always follow the vehicle manufacturer's fuel and maintenance recommendations.

Chevron Techron Treatment Rate

Chevron's current treatment rate for Techron Complete Fuel System Cleaner is 1 ounce of Techron per 1 gallon of gasoline.

For best distribution, Chevron recommends adding the appropriate amount of Techron to a nearly empty fuel tank and then filling the tank with gasoline.

Follow the directions printed on the specific bottle being used.

How Often Should Techron Be Used?

Chevron's current consumer guidance recommends using Techron Complete Fuel System Cleaner:

• Once each season, or
• Immediately before an oil change

Do not exceed two treatments between oil changes.

The current technical PDS also references a 3,000-mile maintenance interval. Because usage guidance can vary by package and application, follow the current product label for the specific bottle being used.

Gasoline and Ethanol Compatibility

Techron Complete Fuel System Cleaner is intended for spark-ignition gasoline engines.

It is compatible with:

• Conventional gasoline
• E10 gasoline
• E85
• Other commercially available gasoline/ethanol blends

It is not recommended for diesel engines. Chevron offers a separate Techron diesel fuel system cleaner for diesel applications.

Catalytic Converters and Oxygen Sensors

Chevron identifies Techron Complete Fuel System Cleaner as compatible with:

• Catalytic converters
• Oxygen sensors

Use the product according to the recommended dosage. Chevron cautions that excessive overtreatment can contribute to fuel dilution and oil thickening, so more additive should not be assumed to provide better cleaning.

Fuel Gauge Sensor Cleaning

Certain gasoline sulfur compounds can contribute to corrosion or deposits on electronic fuel sending units.

Techron contains deposit-control chemistry designed to help clean sulfur-related contamination and restore or protect operation of affected fuel gauge sensors.

A fuel-gauge problem can also result from electrical or mechanical faults, so persistent inaccurate readings should be diagnosed separately.

Two-Stroke and Small-Engine Applications

Chevron also identifies Techron Complete Fuel System Cleaner as suitable for certain gasoline-powered equipment, including:

• Air-cooled two-stroke engines
• Water-cooled two-stroke engines
• Motorcycles
• Chainsaws
• Marine engines
• Four-stroke lawnmowers

For two-stroke applications, Chevron specifies a treatment rate of 1 ounce per gallon of gasoline.

Always maintain the correct fuel-to-oil ratio specified by the engine manufacturer.

Frequently Asked Questions

What does Chevron Techron Complete Fuel System Cleaner do?
Techron Complete Fuel System Cleaner removes deposits from gasoline fuel injectors, carburetors, intake valves and combustion chambers. It can help restore performance and fuel economy that were lost because of those deposits.

Is Techron a fuel injector cleaner?
Yes, but it is designed to clean more than just the fuel injectors. Techron Complete Fuel System Cleaner also targets intake-valve, carburetor and combustion-chamber deposits.

How much Techron should I use?
Chevron's current treatment rate is 1 ounce of Techron per gallon of gasoline. A 12 oz. bottle treats 12 gallons, a 20 oz. bottle treats 20 gallons and a 32 oz. bottle treats 32 gallons.

Should I add Techron before or after filling the gas tank?
Chevron recommends adding the proper amount to a nearly empty fuel tank and then filling the tank with gasoline. This helps distribute the cleaner throughout the fuel.

How often should I use Chevron Techron?
Chevron's current consumer recommendation is to use Techron Complete Fuel System Cleaner once per season or immediately before an oil change, with no more than two treatments between oil changes.

Does Techron work in one tank of gas?
Yes. Chevron describes Techron Complete Fuel System Cleaner as a one-tank cleanup treatment.

Can Techron improve fuel economy?
Techron can help restore fuel economy that has been lost because of harmful fuel-injector and intake-valve deposits. It should not be interpreted as increasing fuel economy beyond an engine's normal operating condition.

Can Techron restore lost engine power?
If power or acceleration has been reduced by fuel-system deposits, cleaning those deposits can help restore lost performance.

Does Techron help rough idle or hesitation?
Fuel injector and intake-system deposits can contribute to poor drivability, hesitation or rough operation. Techron may help when deposits are the cause. Persistent problems should be mechanically diagnosed.

Does Techron help engine knock or ping?
Chevron states that cleaning combustion-chamber deposits can help minimize deposit-related knock and ping. Knock caused by insufficient fuel octane or a mechanical problem requires a different correction.

Is Techron good for direct injection engines?
Yes. Chevron specifically recommends Techron Complete Fuel System Cleaner for direct injected gasoline engines.

Can Techron be used in hybrid vehicles?
Yes. Chevron identifies gasoline hybrid vehicles among the recommended applications.

Can Techron be used with E85?
Yes. Techron Complete Fuel System Cleaner is compatible with commercially available ethanol blends including E10 and E85.

Is Techron safe for catalytic converters?
Yes. Chevron states that Techron Complete Fuel System Cleaner will not harm catalytic converters when used as directed.

Is Techron safe for oxygen sensors?
Yes. Chevron states that the product will not harm oxygen sensors when used according to directions.

Can Chevron Techron be used in diesel engines?
No. Techron Complete Fuel System Cleaner is intended for gasoline engines and is not recommended for diesel engines.

Can Techron clean a fuel gauge sensor?
Techron is formulated to clean sulfur-related contamination that can affect some electronic fuel gauge sending units and can help restore their operation when contamination is the cause.

Can Techron be used in motorcycles and small engines?
Yes. Chevron identifies several gasoline motorcycle, marine, lawnmower, chainsaw and two-stroke applications as suitable uses. Follow the correct treatment rate and the engine manufacturer's recommendations.

Can I use too much Techron?
Yes. Chevron notes that slight overtreatment should not harm the engine, but excessive amounts can contribute to fuel dilution and oil thickening. Use the recommended treatment rate rather than assuming more cleaner is better.
