Hello, I wonder how exactly (especially cleaning) additives change the fuel or add it to the fuel and if they might have the same effect as Aral Ultimate 102? I had got the LIQUI MOLY Pro-Line petrol system cleaner and the LIQUI MOLY Pro-Line direct injection cleaner to test. Amazingly, both additives have almost the same ingredients. In my opinion, when driving, I notice a similar effect as if I was refueling V-Power Racing or Ultimate 102. I wonder if these cleaning additives simply increase the oct number in the petrol, which one says above all to have a cleaner combustion and cleaning. Or differently, does it bring what to combine the injection cleaner with Ultimate 102? Would I be happy if someone has an answer. Greetings 🙂
