I understand it may hold 18 gallons when filled to the vent. My dash average showed 39.9 but I calculated 37.8 IIRC. Its very hard to get fuel down the filler neck without getting the nozzle cutting out often. I wonder if that skews the station pump readout if you have 6 or more nozzle cutoffs?
It might skew the pump reading, but also depending on the car I am told it can mess with the recovery system in the car. Best results always come from using the same method at the same pump. I picked a pump at one of the cheapest stations in the area, and I always go to that pump on a nearly bone dry tank, always pump at the slowest steady fill rate, and always stop filling at the first click. Best we can do to reduce data noise with crude equipment.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
