I've done searches here and am not finding anything specific. I went to use my windshield washer fluid and the motor ran, but nothing came out. I checked the reservoir today and it's bone dry. Guess Genesis doesn't top your fluids when you bring it in for service? One would think that when paying for an inspection they'd notice the empty washer container. Ahh, but I digress. Is there a specific brand of windshield wiper fluid recommended for these G90's? Thanks?
