In our family we have an Austin Mini 1100 Special with EZ 04.01.1977. The engine was rebuilt 3 years on unleaded to 57,500 original kilometers. The engine therefore often go on kurzstrekken. After very good experiences with our oldtimer Porsche and Liqui Moly Injection cleaner that we have tried MTX 5100 Liqui Moly. We have not been back entauscht. After adding the fuel and a fuel-tour about 60km everything is wierder perfectly fine. A week later the nächtes trip and the car ran well from the outset directly and around. We did not have long. And this in a car which is now 35 years old is! We are excited. Super-Duper! Thank Liqui Moly! Liqui Moly 5100 mtx Carburetor cleaner, 300 ml
