Cayenne 4.8 engine jitter problem, have any buddies encountered it?

This is the only way to clean the oil circuit regularly. Before, my car was idling and the exhaust pipe was black. The master couldn't check the problem and finally said it might be carbon deposition.

Give me two Siyoupu fuel additives and pour them into the fuel tank. It's smooth after two sesame oils. The exhaust pipe is now metal. I think it should be caused by carbon deposition and unclean oil circuit.

Sioupu is developing household fuel, and domestic gas stations will also use cleaning agents similar to Sioupu when cleaning underground oil storage tanks regularly. Siupu is also providing solutions and products for cleaning oil storage tanks in gas stations.

The fuel before the gas station cleaning is added to the car fuel tank, and the private car should clean and maintain the oil circuit in time. Siyoupu fuel additive can not only remove carbon deposits caused by improper maintenance,

More can be used to maintain impurities, colloidal water and other substances that are not conducive to combustion caused by long-term failure to clean the oil circuit, so that the car can burn more fully and better. Avoid carbon deposition caused by poor combustion for a long time.

Therefore, Siyoupu is not only an additive for cleaning up carbon deposits, but also an additive for preventing carbon deposits and maintaining automobiles.
