Review on Liqui Moly 2001 Valve Clean by Micha Dziubiski ᠌

In December 2022, the check engine light came on on the dashboard. Gasoline car. Mileage is about 100,000. I have never poured anything into the fuel. Refueling only LUKOIL. Onboard gave error 172 - mixture too rich. The error was not removed onboard (although this was very rare during regassing, but it was filmed). After pouring LIQUI MOLY Injection Clean Light after about 40 km, the check went out by itself, the onboard one reset to zero. I don’t know what was washed in the injector, but the fact is obvious.
