Anyone got any expertise on E10 petrol and it’s effect on BHP and running in V6 and i4 AMG engines? For example, reliability and power delivery?

Here’s the official Lotus position on E5 and E10, which covers the V6: https://www.lotuscars.com/en-GB/fuel-compatibility/

For engines with forced induction like the supercharged V6, Lotus recommend super unleaded (97 RON or higher). You can use a lower rated fuel but the ECU will adjust accordingly and you’ll get lower performance. In the UK I think 97+ RON fuel is staying as E5.

Mercedes say all current AMG engines are E10 compatible but with a slight impact on fuel economy and performance, around 1%. They recommend super unleaded too, but will also run on regular unleaded with lower performance.
