Do you know these pictures are patted from where?

Do you have an attention to pass photographs of these bloodcurdling there is a place?

I can tell you very responsibly:

These are engine completely in accumulate carbon!

Engine is after long-term movement, inevitable meeting generation is accumulated carbon and colloid, especially engine of turbine pressure boost. If keep clear of not in time, deposit inside piston chamfer accumulate carbon, cause compression ratio to greaten engine combustion is undesirable. Deposit is in of lubricant system accumulate carbon to still can cause engine oil to pollute, oily bad news increases, power drops, serious when can jam oil duct, cause pull a crock, hold the serious consequence such as tile in the arms.

Protective engine begins from the engine oil that has chosen!

Feng Tianke protects engine oil of vegetable of black lead Xi

Use castor oil and black lead Xi to be main raw material, have extremely strong adsorptive sex and liquidity, as engine run, oily film is formed between each machinery component, prevent air to enter, OK and very good cleared engine accumulates carbon, reduce engine dimension to maintain a volume considerably thereby, prolong engine life.
