I was always told by well-known companies: other valves, gasoline pipes, gasoline pump, petrol tank and software valves-> lubricates less therefore harder valves pipes and pump -> is agressiever therefore other sealant software -> more throughput since e85 has less energy there but tec2 where only software is made and that with abe the ADAC also the hardware has to be exchanged, what is the now correct ?? thank you
