Hi Guys,
Today I stopped by my local BMW Zentrum and asked my guys there about E10. They were nice enough to give me a document that BMW has put out to all the German dealers.
Basically any BMW produced after 2000 M.Y. it is ok to run E10 in it. But the car will perform better with Super (E05) or with SuperPlus.
My guy there said I could try/test the E10 fuel - but most likely I would notice less performance and less fuel economy with E10. He said it is better to run SuperPlus - but that is up to the owner/driver. The car CAN run on E10. But in the end of our converstation... he said its a performance car and it is better to feed it SuperPlus. Just what I thought going in. So... I will stick with SuperPlus 98 in my car!
Here is the internal BMW document. I hope you can read it. (its in German!) Basically all the BMW models listed in the box bellow CAN NOT use E10 fuel and MUST run SuperPlus!!!
