SPRAYTED

Hi everyone, nice to meet you. I got a lot of questions about my Lupo 1.4 16v Automatic based on AUA engine's references with 75 HP or 55 kW power. She got 130k+ kilometers. I'm wanting to know if a fuel changeover from Unleaded Petrol (or SP95 in European Union) to E85 (always to name given in European Union, the name in US or England, I think is Super-Ethanol, not sure), was possible. I know risks where I go on and consequences I will have if I do it badly. And an other question, can I upgrade some parts for a better performances from this car ? That's for your responses
