Does Skoda Ming Rui 1.2t7 km engine need cleaning?

It's 70 thousand kilometers. It's time to clean up.

Engine operation will inevitably produce carbon deposits, which need to be cleaned regularly, and can be cleaned according to the road conditions and mileage of the vehicle. If the vehicle is driving in urban areas for a long time, it is recommended to clean the throttle body every 15000 km, and clean the intake and injector every other year or 30000 km.

The cleaning method is as follows:

1, pump out the bottle, cut off the fuel supply, connect the carbon deposit cleaning agent to the engine nozzle, and use the cleaning agent to soften the carbon deposit in the engine for combustion and discharge, but this method is only suitable for slight carbon deposit, which is of little significance to those vehicles with serious carbon deposit;

2. Disassemble the engine intake branch pipe for cleaning, remove the engine intake branch pipe, then scrape the stubborn carbon deposit clean, and then load the car after cleaning. This is the best and most obvious effect. The cost is not much different from that of infusion bottles.
