My service rep recently told me that BMW had informed them that their testing showed that there was no longer a need for me to put premium fuel in my car. Instead, I was told that I could safely use mid-grade or even regular fuel. And, the car would run fine.
Being a skeptic by nature, and having a number of Dinan add-on's on my car, I posted this query on anther BMW related board. The advice I got was to call Dinan. I did. I was told that it would be best for me to use a fuel of at least 91 octane in my car because that's what their products are made to run on. (I have a Dinan throttle, exhaust system, cold air return, engine and trans chips.)
My service rep still says that I don't have to use premium. And the service manager backs him up. What do you guys think. For $.20 a gallon, is it worth it?
