e10 will likely be the same wherever, buy fuel stabiliser or look at youtube for tutorials on how to remove the ethanol

Evidently, you can still get E5 fuel if you purchase the "super" kind, of whichever brand you fancy.

I don't recommend processing/handling gallons of fuel out of the tank, you'll also end up with gallons of ethanol with no disposal route.

The biggest problem is that it melts rubber fuel lines (not in an MPI), perhaps it has rubber seals though. Worse, in your lawn mower or anything with a float bowl it can eat through the soldered (?) float in the bowl and it sinks. Ethanol also causes the fuel to absorb more water and this then sinks to the bottom of your tank and starts to rust it inside to out.

I don't know how effective they are - but I do know that addtived are expensive. Significantly more than then cost of "super" petrol. Your MPi WON'T benefit (in terms of power) from the higher octane rating of "super" fuel, but it will benefit having less added ethanol sloshing around the tank.

Do so, but know that your Mini wont benefit the higher octane unless it happens to have had significant work done resulting in a higher compression ratio, and therefore NEEDS it to prevent pre-ignition. The only benefit lies in that they contaminate it with 5% ethanol rather than 10%.

I'm not sure what else I can do.
