Rislone Super Concentrated Fuel Injector Cleaner with Upper Cylinder Lubricant is the best all-around fuel additive to use with every tank of fuel. This complete fuel system tune-up helps eliminate noisy injectors & fuel pumps, rough idle, hard starting and hesitation. High performance additives maximize power, performance, kilometres and help save petrol by cleaning & lubricating fuel injectors.

Regular use, summer and winter, maintains optimum engine efficiency and power.

  • Smooths rough idle and eliminates hard starts giving cleaner, quieter operation.
  • Cleans fuel injectors, increases kilometres and saves on high fuel costs at the pump.
  • UCL, Upper Cylinder Lubricant, helps prevent cylinder, ring & piston wear along with lubricating valves & guides giving longer engine life.
  • The Fuel Conditioner & Treatment protects and lubricates all parts of the fuel system including the fuel pump and injectors allowing more power & performance.

Use with all petrol, ethanol E10 E85 and diesel fuels.

Works with all fuel injected, turbo, direct injected & carbureted engines.

EZ Nozzle™ works in all vehicles including capless fuel tanks.


Dosage & Directions

Remove cap by squeezing and turning at the finger tabs and remove foil seal. Gently tip bottle and completely insert spout into fuel tank opening, allowing entire contents to empty into tank. Results will be either immediate or noticeable within a few days of driving.

Rislone Fuel Injector Cleaner is compatible with Rislone Diesel Treatment and Rislone Octane Booster.

One bottle is concentrated to treat up to 76 L of petrol or diesel fuel. For small engines, use ¼ bottle for every 19L.

Safe to use on vehicles with oxygen sensors, catalytic converters and particulate filters. Will not void manufacturer’s new vehicle warranty.

Unique formulation allows it to work in both petrol and diesel fuel engines. For diesel applications this fuel additive complies with the federal low sulfur content requirements for use in diesel fuel motor vehicles and non-road engines.

Upper Cylinder Lubricant 
The Rislone Upper Cylinder Lubricant (UCL) additive is specially designed to lubricate the upper cylinder of an engine; however this action starts in the fuel tank. This UCL formulation helps overcome the lack of lubrication in modern fuels including unleaded petrol, ULSD diesel fuel, E10 E85 Ethanol, and other oxygenated and bio fuels.

In the fuel tank, UCL helps prevent rust & corrosion and this process continues into the fuel lines. UCL also lubricates and protects the fuel pump, giving it a longer life and quieter operation.

The next step for the UCL formula is to lubricate the injectors allowing them to work more efficiently. Not only are cylinder deposits cleaned, including gum and varnish, but as the UCL treats the upper cylinder the lubricating film helps to prevent carbon from sticking so that it can be burned. This film completely lubricates the upper piston, rings, guides, valves, and seats.

Note: This bottle includes a patent pending nozzle and flow valve which allows it to be easily poured into ALL fuel tanks, including capless (no fuel cap) systems. This flow valve delays the start of pouring to help prevent liquid from spilling and damaging the vehicle finish like other competitive brands.

What does Rislone Fuel Injector Cleaner do?
With continued use, it reduces carbon build-up which causes pre-ignition, power loss, burned valves and broken rings. It also cleans injectors to reduce loss of fuel economy, hesitation, pinging (spark knock), and helps restore performance.

How does Rislone Fuel Injector Cleaner work?
This product contains a unique blend of additives that clean & lubricate the entire fuel system, including fuel tanks, lines injectors, and even carburetors on older vehicles.

How can this reduce a noisy fuel system?
The UCL (Upper Cylinder Lubricant) additive lubricates the fuel pump, injectors and upper cylinder to reduce friction & wear, reducing noise.

How much will my fuel kilometres improve?
This varies depending on the age of the vehicle, the quality of the fuel used, and how dirty the system is. It is normal for larger increases in KPL on the first dosage and then it will usually taper off and flatten out from the second dosage on. For best results use with every tank of fuel.

Can this replace the lubricant in the ULSD Ultra Low Sulphur Diesel Fuel?
Yes, Rislone Fuel Injector Cleaner with Conditioner & Treatment is an excellent lubricant and will replace the lost additives in the new reformulated diesel fuel.

Will this harm the oxygen sensors or plug the catalytic converter?
No, this will not harm your engine or any emissions components including catalytic converters, oxygen sensors, or the EGR valve.

How much do I use?
One bottle is concentrated to treat up to 95 litres of petrol or diesel fuel.

Can I use in E-85 ethanol in my flex-fuel vehicle?
Yes, Rislone Fuel Injector Cleaner with Conditioner & Treatment works with the E-85 and will lubricate the fuel system reducing the negative effects that ethanol has on the system.


"My car had rough acceleration, after using Rislone Fuel Injector Cleaner.. Wow!... I noticed the difference within 5min of driving.. Totally worth every cent.. I did try all other product but Rislone worked fastest and gave the best result."
