Rislone – Petrol Fuel System Treatment with Fuel Injector Cleaner

Rislone is a historic American automotive brand, founded in 1921, specializing in chemical additives that improve, protect, and restore engine and fuel system performance. Known for pioneering products like Engine Treatment and its “tune-up” system, Rislone has served both everyday motorists and organizations such as the U.S. Navy and Ford Motor Co. Today, the brand continues to offer modern solutions for cleaner, more efficient, and better-performing vehicles. The Rislone Fuel Injector Cleaner is a concentrated additive ...that cleans fuel injectors and lubricates upper cylinders via the fuel system, helping eliminate injector/pump noise, rough idle, hard starting and improving performance and mileage. The Rislone Petrol Fuel System Treatment is a comprehensive gasoline-engine fuel additive that cleans the full fuel system (tank to combustion chamber), adds lubrication, removes contaminants, boosts octane, stabilises petrol and combats water in the fuel-restoring lost power, improving efficiency and protecting the engine.

Rislone Petrol Fuel System Treatment

What it is:

• A more comprehensive fuel treatment for petrol (gasoline) engines from Rislone. Sometimes labelled “Complete Petrol Fuel System Treatment” or similar.
• Designed to treat the full fuel system (tank, lines, injectors, valves, combustion chamber) rather than just injectors.

What it does / benefits:

• Improves quality of petrol by increasing cleaning ability, adding lubrication, removing contaminants.
• Reduces spark knock/mis-fires (via octane booster component) and helps prevent fuel from “going bad”.
• Cleans deposits from injectors, valves, intake manifold, combustion chambers
• Compatible with all types of fuel injected, direct injected, carbureted, turbocharged etc. Also works with ethanol blends (E10, E15, E85).
• Contains multiple functions: injector/fuel system cleaner + upper cylinder lubricant + fuel stabilizer/conditioner + water remover (“dry petrol”) + octane booster.

How to use / dosage:

• One bottle treats up to about two tanks of fuel (for example up to ~68 litres/18 gallons in one listing) depending on size.
• Use when tank is nearly full or after adding. Works in capless and regular fuel systems.
• For best results, use at regular intervals (e.g., every ~5,000 miles or with each oil change) to maintain clean fuel system.

In summary:
This product is a “complete” fuel system treatment for petrol engines. It goes beyond just injectors: it treats fuel tank, lines, valves, combustion chamber, adds octane boost, cleans deposits, adds lubrication, removes water. Good for overall system health and performance.

3. Key Differences & When to Use Which

• If you’re specifically dealing with injector issues (noisy injectors, rough idle, pump noise, hesitation) then the Fuel Injector Cleaner is targeted for that.
• If you want a broad-spectrum treatment of the entire fuel system (tank, lines, valves, combustion chamber) for petrol, plus benefit of octane boost and water removal, then the Petrol Fuel System Treatment is the more comprehensive solution.
• The “treatment” version is especially useful for preventative maintenance or when you suspect your fuel system has accumulated deposits over time or you’ve used low quality fuel.
• The injector cleaner can be used more regularly (e.g., with each fill or every few thousand km) as maintenance; the treatment can be used less frequently (every few thousand miles) to reset/clean the system.

Rislone Fuel Injector Cleaner

What it is:

• A fuel-system additive from Rislone (also called “Fuel Injector Cleaner with Upper Cylinder Lubricant”).
• Designed to clean fuel injectors (and surrounding fuel system components) and to provide lubrication to the upper cylinder area via “Upper Cylinder Lubricant (UCL)”.

What it does / benefits:

• Helps eliminate noisy injectors and fuel pumps.
• Helps smooth rough idle, eliminate hard starts and hesitation.
• Increases power, performance, acceleration response, fuel efficiency/mileage.
• Lubricates fuel system components (injectors, fuel pump, upper cylinder rings/valves) to reduce wear.
• Compatible with gasoline, and in some versions also with diesel, ethanol blended and bio-fuel types.

How to use / dosage:

• Typically you pour the full bottle into the fuel tank. One bottle treats up to a certain amount of fuel (varies by size).
• Use it regularly (e.g., every fill-up or every few thousand miles) to maintain clean injectors and fuel system.

Key ingredients / notes:

• The cleaning action is achieved via a “Premium P.E.A. (Polyetheramine) New Generation Detergent” formula (for certain versions) plus petroleum-based oils for lubrication.
• Includes the UCL (Upper Cylinder Lubricant) to protect upper engine parts through the fuel system.

In summary:
This product is focused on cleaning and maintaining the injectors and related fuel system parts, and giving a lubricant boost to upper engine parts via the fuel. It addresses injector noise, pump noise, rough running, performance drop, etc. What’s in the box
