Do fuel additives work?
Will it actually improve fuel economy and eliminate water in the fuel?
Will automatic transmission fluid do the same thing?
Richard,
I think they work. I have used them since I bought the coach, mainly because it sits for long periods. I do try to keep tank pretty full also and treat every gallon. I used White Power Service for years, bought it in 1000 gal treatment for farm, but I think they changed it. At least I read the label and it didn't seem right anymore.

So I switched to Sta-bil last year.

Had to change the racor out after 2000 miles, but the coach had sat in Florida for five months I assume it was Florida and not the treatment change. Or I got some drity fuel.
I only fill up at Flying J.
I would be interested in knowing what others use.
