That's for sure. Just switching from 98 RON to 102 RON pump gas makes quite a difference. Not a hughe one (will never gain 70hp that way), but one I can definitely feel.

Yep, it already happened that I ran ~E30 for pushing the limits. E30 runs well, never went higher cause it's know not to work very well on stock fuelling.
Nevertheless I see that kind of mixture more like a "weekend mix". As that car is my daily and I don't want to bother with mixing during the week.
The idea would be that I would fill up always at the same place near home, 0,6€/L E85, instead of 1,30€/L 102RON gas near work. E85 price is stable, pump gas always increases. That's for me a gain of time, peace of mind, and a gain of money after the fueling system's cost was covered by the price difference, which should come fast. This car covers between 25 and 30000 km / year.

Today I’m on JB4 over the BMW MPPK with no other sort of BEF.
