Injector Cleanliness

* Deposit on the spark plug and/or combustion chamber can be easily removed. Also, high concentrated Hyper-succinimide can remove deposit on injectors of the diesel engine so the original engine performance can be easily recovered.

Cetane Number improved by 3 points

* Tested at an outside research center.

* Cetane number is a measure of fuel's ignition delay; the time period between the start of injection and start of combustion (ignition) of the fuel. The range of cetane numbers is usually from 15 to 100. Higher speed diesels operate more effectively with higher cetane number.

Gas oil lubricity improved.

*100℃x700 hours soaked (4000volppm). 
No metal corrosion was found.

Frequency of Use
  • Add 250ml of DDR per 75L fuel.
  • Add every 6 months or 5000km.
Direct Deposit Remover Premium

Exclusive for Chinese Market

New DDR Premium is launched with new ingredients derived from our bestseller existing DDR gasoline and improved removing performance of injector water-soluble deposits.

DDR efficiently removes oil-soluble and water-soluble deposits in the injector, intake valve, plug, and combustion chamber.
Recently, new types of deposits tend to be generated at the port injection engine due to improved engine efficiency. This kind of deposits is difficult to remove with existing additives.
New DDR can remove this kind of deposits with new active ingredients and it can be expected to provide better overall effect.

How to use

  1. Pour this product into the Gasoline tank. (One item for up to 75L gas tank)
  2. Additional fill up afterwards is not required. Use vehicle as usual until the fuel tank gets nearly empty. *It can be used at a tank with low fuel. However, we recommend to use it at full of gasoline for bringing out high performance.

* Recommended to repeat every 5,000km or 6 months whichever comes first.
