Liqui Moly Jectron Gasoline Fuel Injection Cleaner 2-Pack — Restores Injectors & Improves Idle

Liqui Moly Jectron Gasoline Fuel Injection Cleaner (2-pack) is a concentrated additive that dissolves carbon and fuel deposits to restore injector spray patterns, improve idling and lower fuel consumption.

This two-bottle kit is formulated for petrol engines and is compatible with catalytic converters. It targets deposits in fuel pipes, injectors, distributors and inlet valves so engines regain smooth throttle response and stable idle without aggressive mechanical cleaning. The formula supports accurate dosing and improved atomization so combustion runs cleaner and more efficiently.

How does Jectron improve engine performance?

Jectron works chemically to break up and remove varnish and carbon that build on injectors and intake components. By clearing those deposits the injector spray returns to its designed pattern, which helps fuel mix more evenly and burn more completely.

• Restores injector spray geometry for more even fuel distribution
• Reduces misfires and lean surging by cleaning inlet valves
• Helps the engine run with smoother idling and better throttle response

When and how should I use the 2-pack?

Use one bottle per full tank treatment or follow manufacturer dosing on older engines; the two-pack gives you a second service interval or coverage for two vehicles. Add the cleaner directly into the fuel tank before refuelling to ensure rapid mixing and even distribution through the system.

• Add dose to a near-empty tank, then fill to mix thoroughly
• One bottle commonly treats one tank; keep the second for the next maintenance interval
• Safe for engines equipped with catalytic converters when used as directed

What benefits can I expect after treatment?

After the cleaner circulates through the fuel system you should notice fewer starting issues, reduced hesitation under load and smoother idling. Over time, improved atomization and cleaner combustion often translate to modest reductions in fuel consumption and lower emissions from unburned fuel.

• Better throttle response and reduced rough idling
• Lower fuel consumption from cleaner combustion
• Reduced carbon build-up that can affect long-term performance

Is it safe for modern fuel systems and catalytic converters?

Jectron is formulated for petrol engines and is suitable for use with catalytic converters when used according to the label. It is designed to dissolve deposits without harming seals, sensors or emission-control components, but always follow dosing instructions to avoid overdosing.

• Compatible with catalytic converters when used as directed
• Does not require disassembly—works while engine runs normally
• Concentrated formula for one-tank treatment per bottle

Who is this for: Liqui Moly Jectron Gasoline Fuel Injection Cleaner (2-pack) suits drivers and DIY mechanics who want to maintain petrol engines between service intervals, reduce hesitation or starting problems, and preserve fuel economy without invasive mechanical cleaning. It's particularly useful for older vehicles showing mild deposit-related symptoms, performance-conscious motorists looking to restore throttle response, and workshops stocking a reliable, OEM-friendly injector cleaner for routine maintenance.
