[DeBella]

Cleaning agents such as 3M, BASF, or Chevron brands can be chosen. Additional information is as follows: 1. Due to the large amount of dirt, the cleaning process may cause oil passage blockage and poor lubrication, or even lead to bearing burning, so it should be used according to the situation. 2. Effectively clean the engine lubrication system, removing the oil film and sludge formed by old engine oil; effectively utilize the lubricating performance of the oil and enhance oil fluidity; can neutralize long-term harmful acidic substances generated inside the engine. 3. The cleaning agent is directly added to the fuel tank and mixed with the fuel. When the vehicle is started, the cleaning agent will enter the combustion chamber along with the fuel, and while the cleaning agent enters the combustion chamber, it will clean the carbon deposits inside the engine to a certain extent.
