me and my powerlifting meathead friends used to argue about a similar thing. i.e. whether loading 3 45lb plates on each side was easier to bench than the equivalent of smaller plates (say 13 10lb plates on each side). we never did experiment.
I had the same experience, same year/model. I did use the washers a couple times briefly. then, the "low washer fluid" message came up. took most of a container of fluid. if the dealer, not ford is supposed to fill it, someone messed up. was going to contact the dealership (Westpoint ford in VA)...
im a tech dummy.... in Williamsburg. bought a 26 awd lariat in late June. over 6k on it already. love the thing. wish I had the sunroof though. sales guy never told me they were available. would like to meet up with other maverick owners.
I have a 26 lariat awd and getting an average of 40 mpg (8 liters per 100 mi) on a good mix of city/highway w/AC on 100% of the time. 6000 miles on it now have to see if mpg gone up.
