What is Redex Oil?

Redex Oil is a fuel additive designed to clean and protect petrol and diesel engine systems. It was originally developed in the 1920s by Castrol and has been used by motorists for over 90 years to help improve engine performance and efficiency.

Redex Oil is formulated using a blend of active ingredients that work to remove deposits, dirt, and debris that can build up in fuel systems over time. As engines accumulate these contaminants in the combustion chamber, injectors, valves, and filters, it can lead to rough idling, poor acceleration, reduced power, increased emissions and decreased fuel economy. Redex helps restore smooth engine performance by dissolving away these harmful deposits.

It is an all-in-one fuel treatment that provides multi-function cleaning power. Just by adding Redex to the fuel tank, it gets to work deep inside the engine breaking down sludge, gum, varnish while also preventing rust and corrosion. This keeps the entire fuel system operating at peak efficiency.

Key Ingredients

Redex Oil contains several active ingredients that provide its cleaning and lubricating benefits for engines. The main ingredients are:

  • Detergents - Help clean away deposits, sludge, and other impurities from engine parts like pistons and cylinder walls. This helps the engine run smoother.

  • Dispersants - Break up sludge and prevent deposits from reforming. Keeps engine parts cleaner for longer.

  • Anti-oxidants - Help prevent oxidation and corrosion of metal engine components. Reduces wear and extends engine life.

  • Friction modifiers - Coat metal surfaces and reduce friction between moving parts like pistons. This improves performance and fuel economy.

  • Rust inhibitors - Prevent rust formation on engine parts, especially during storage. Protects the engine from damage.

  • Anti-wear additives - Form protective layers on metal and reduce friction. Prevents excessive wear and prolongs engine life.

The combination of these ingredients in Redex Oil provides a potent cleaning and protection formula for vehicle engines. The detergents, dispersants and anti-wear additives keep critical engine parts clean and well-lubricated for smooth operation and reduced wear over time.

How Redex Oil Works

Redex Oil works through a combination of powerful detergents and additives that help clean your engine and keep it running smoothly. The key ingredients that allow Redex Oil to effectively work are:

  • Detergents - Redex contains strong detergents that can break down carbon and sludge buildup in the engine. As the oil circulates, the detergents lift away deposits from internal engine components. This helps remove harmful contaminants.

  • Dispersants - Redex contains dispersants that hold contaminants in suspension once they are lifted off surfaces. This prevents them from re-depositing elsewhere in the engine. The dispersants allow the contaminants to be carried safely in the oil until drained.

  • Friction modifiers - Redex contains friction-reducing compounds that help make metal surfaces smooth at the microscopic level. This allows engine components to move freely and reduces overall friction and wear. Improved lubrication minimizes damage to critical parts.

  • Anti-wear additives - Redex contains anti-wear agents such as zinc dialkyldithiophosphate. These form protective layers on metal surfaces under high pressure, preventing scuffing and damage. This provides additional engine protection.

The combination of detergents, dispersants, friction modifiers, and anti-wear additives in Redex Oil enables it to effectively clean contaminated engines and reduce friction and wear. Regular use keeps engines running smoothly.

Benefits of Using Redex Oil

Redex Oil provides a number of benefits when used properly in your vehicle:

  • Improved Engine Performance - The detergents and additives in Redex help clean deposits and buildup from critical engine components like valves, pistons, and injectors. This improves airflow, combustion efficiency, and throttle response. Your engine will run smoother and have more power.

  • Increased Fuel Economy - Clean injectors, valves, and combustion chambers allow for better fuel atomization and complete burning. This means you get more miles per gallon as less fuel is wasted. Estimates show fuel economy gains of 3-5%.

  • Reduced Emissions - The complete combustion of fuel also leads to lower emissions from the tailpipe. Redex can help your vehicle produce less harmful exhaust gases like hydrocarbons, carbon monoxide, and nitrogen oxides.

  • Engine Longevity - By keeping critical components clean, Redex allows your engine to operate at peak efficiency for longer. This reduces wear and can extend the operating life of the engine.

  • Smoother Idle - Redex helps clean carbon deposits that can cause rough idling. It smooths out idle and reduces stalling.

  • Decreased Engine Noise - By removing deposits, Redex Oil reduces tapping, knocking, and rattling sounds from the engine for quieter operation.

  • Improved Cold Starting - Redex dissolves gum, varnish, and sludge that can cause poor cold starting, especially in cold weather. It improves startup and reduces cranking time.

So in summary, Redex Oil provides a broad range of performance and efficiency benefits when used on a regular basis. Drivers will notice smoother operation, better throttle response, increased power, and significant fuel savings.

How to Use Redex Oil

Using Redex Oil is straightforward. Here are the steps for adding it to your fuel tank:

  • Read the instructions on the bottle for the proper dosage amount based on your fuel tank size. Redex Oil should be added at a ratio of 1 part Redex to 1000 parts petrol.

  • Open the fuel filler cap of your vehicle.

  • Pour the correct amount of Redex Oil slowly into the petrol tank. Avoid spilling.

  • Replace the fuel filler cap securely.

  • Start the engine and allow the vehicle to idle for 5-10 minutes to allow the Redex to circulate through the fuel system.

  • Drive as normal. The cleaning agents in Redex will get to work dissolving deposits and cleaning critical engine components.

  • For optimal results, use Redex Oil every 3000 miles as part of your regular maintenance schedule.

Recommended Treatment Schedule

Redex Oil should be used regularly for preventative engine maintenance and optimal performance. The recommended treatment schedule is as follows:

  • For normal driving conditions, add one bottle of Redex Oil every 5,000 miles or 6 months, whichever comes first. This helps clean deposits and prevent future buildup.

  • If you do mostly short trips or city driving, increase frequency to every 3,000 miles or 3 months. Short drives can cause more carbon deposits.

  • For high performance engines, racing applications, or modified engines, treat with Redex Oil every 1,000 miles for maximum cleaning and protection.

  • When changing oil, add Redex Oil during the oil change for extra cleaning boost.

  • Use one bottle per oil change or as directed on bottle. Do not overfill.

Following this routine treatment schedule will keep your engine running smoothly, improve fuel economy, and prevent costly repairs down the road. Consistency is key to maximize the benefits of Redex Oil. Check your owner's manual for any specific recommendations.

Safety Precautions

When using Redex Oil, it's important to take the following safety precautions:

  • Use gloves and eye protection when handling Redex Oil, as it can irritate skin and eyes. Avoid contact with skin and wash thoroughly after handling.
