Ouch, may be BMW gotta make a list of approved gasoline brands, lol
I told SA that I purchased the car, and I am planning to keep this car until the end of its design life cycle or even longer. Therefore, I am not going to be penny pinching on gas and filling it with 89 or 87 gas.
My friend leased Z4 sDrive35i a few years ago. He told his wife that lease end is coming up soon, so he is going to cheap out on gas and fill it with 87 octane. The moment he pulled out from gas station and floored it, the engine check light lit up.
