M2 LCI N55 STOCK Can Fuel E20 ?

My fuel tank cap says do not add more than 10% ethanol.


Will it have any effect on the engine?
In the case of refilling E20 (ethanol20%)

The country i live in Hot weather all year round

I don't have a plan to tune the car.

Sorry my english is not good

I wouldn't recommend it, but yes the ecu should be able to adapt and the car will be able to run on E20 w/o a tune.

The N55 M2 can handle E30 with stock turbo, then hpfp starts crapping out. Tune of course needed to take advantage of it. Bm3 stg 2 e30 tune with stock turbo gives a nice add.

Mixing/ adding more E then in your original fuel won’t give you more so just keep running normal fuel (which here is 5% ethanol).
