When I first got my car I was getting around 210-220 miles per tank.

It's an E93 M3 with 90% city driving in hot and humid Miami.

Over my last few fills i'm noticing my mileage getting lower and lower.

It went down to around 200 miles per tank. Then I was getting around 190 per tank. On my last tank I only managed 179.

I have not changed my driving style and the weather here has actually gotten a bit cooler.

I'm scheduled for my next maintenance service in October. Is there anything in specific I should tell them to check to see what the issue could be?
