Then how are you certain you are getting worse mileage if you fill it to different levels each time you put gas in? If you put 10 gallons in one time and 4 gallons the next time of course you are going to get "worse mileage". The reason being is you are getting less mileage out of the 4 gallons than 10. My truck "tells me" it get's good mileage from full tank to 3/4 and then the needle moves faster between 3/4 and empty. I'm sure others see the same thing with their gas gauges.
Reason for that, the computer is sending too much fuel to the engine due to the old information stored in the computer from before the fuel filter change. Hope that makes sense.
Even if my needle was off by a gallon, a 20 gallon tank is roughly 5 gallons for every 1/4 tank. I shouldn't have went through 5 gallons for a 30 mile trip. Even if it was 3 gallons off, I shouldn't go through 2 gallons on a 30 mile trip.
