& Answer

A few things clients normally ask us about CLEANTECH Engine Flushing Fluid.

What is carbon sludge?
  • Inside the engine, oil becomes carbon sludge by high-temperature, high-pressure combustion gases.
  • Carbon sludge is non-adhesive and is largely filtered by oil strainers and oil filters.
  • However, about 20% of the carbon sludge sticks to the aluminum surface inside the engine to form a mass of sludge.
  • This sludge mass is not removed by a simple engine oil change.
How do I remove this sludge mass?
  • The most reliable method is to break down the engine and remove visible sludge mass by mechanical or chemical means.
  • However, this method is difficult in terms of cost and time.
  • If you use CLEANTECH every engine oil change cycle, there is no reason to clean the engine at a high cost.
Can I use large-capacity CLEANTECH for the motorcycles?
  • Of course, there is no problem with using it. Rather, it is positive in terms of cost reduction.
  • Put 100ml per 0.8 ~ 1.6L Engine Oil Capacity.
