Call Yan Version: Removing carbon deposits is really a surprise

September 5, 2024

The E300L in April 2014, the last batch of 3.0 naturally aspirated engines, was exactly 8 years old and 97,000 kilometers.
I was running at high speed in February this year and found that the fuel consumption was more than 10. I felt that it was time to clean the carbon deposits. I remember that the new car had less than 8 fuel consumption at high speed.
I started looking for a dry ice cleaning shop in Jinan, and found that the prices were not as cheap as Yan Bianfa. I finally chose to do it in a 4S shop. Buy it with peace of mind. In the end, I had mixed feelings.
I cleaned the intake port + throttle before May Day, and finally found that the dry ice was out of stock. After the goods arrived after the holiday, I washed the cylinder with dry ice.
