Just stick to E5, my Plus 8 has been on Super for the last 7 years anyway, it's a toy and I believe you can overthink these things, time is better spent driving them whilst we still can
In real terms it won't cost more than + - £150 for the E10 difference p.a. so a couple of tanks in reality..
IF and when we are approaching an E10 only time I'll look into changing hoses, meantime just get on with some quality miles..
Don't panic Mr Mainwaring springs to mind with this one
