    Like a number of you, mpg from my 3rd gen anchors my OCD. (I’m getting 54 mph combined with a new Nexpower v3 GT and currently replacing plugs, coils, A/F sensor and cleaning injectors to get one or two more)

    That being said, love the the 17” 5 spoke rims. Currently have 15”. Will my mileage suffer if I give into vanity?
