Hey so I just picked up my 2024 M240i last week and I have suspicions that my dealership filled my car with a full tank of regular gas. A few reasons I suspect this is the smell of the gas, engine not sounding how I’ve heard others with a g42 sound (still only has 200 miles also),gas is burning very fast even though I am driving conservatively, this dealership is constantly trying to find ways to cut costs and help themselves before the customer, and Premium where I live is $5 so I can definitely see them not wanting to fill a tank with premium. Is there a way for me to test the gas? I have just been driving it around trying to drain the gas Im at about 70 miles till empty now until I can fill it myself for the first time. I really want to make sure this car has a long healthy life so will this effect that? I wish I knew they were going to do this because I would’ve just told them to not fill it at all. Any recommendations or advice would be appreciated thanks!
Dude I work at a bmw Factory and they put regular in too. Your engine’s fine. You could put 87 in forever and it would just make less power and get worse MPGs
