So how many years has ethanol been in our gas? How many BTU's of energy do you think they pack in 2.5 oz of injector cleaner.
IMO the problem with ethanol is it gums up after about 8 weeks. So the real question is in 8 weeks how many tanks of fuel does the average MH burn up. Most Class A's I see the weeds are pretty tall around them so I'm guessing none. In that light, if MH don't get used that often what do you think the fuel tank look like (crud, rust, etc...) might explain the filters needing to be changed often.
When I was lucky enough to find non-ethanol gas my F53 would only get a slight increase in MPG. What I did notice was the power I had when going up hills pulling a car.
To the OP, run the correct ratio of SeaFoam to gas (at least 1/2 tank worth), then change the filter. After that see if you're back to normal or not.
