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.
