So in reading the Gumout FAQ (this one and this one), it states using Gumout All in One (AIO) in an every tank maintanance dose is acceptable. I have a bunch of Gumout AIO (thread about how much I actually have) that will take me a few years to go through, so I am debating using ~1/2 oz per tank in my 1994 Honda VT1100 Shadow (~ 2.5 - 3 gallons per fillup). I may miss a tank here and there due to filling up away from home, but no big deal overall. One of the benefits of AIO is it is an ethanol treatment, and since I have no ethanol free gas around me, a good thing for a 23 yr old vehicle I think. Not exactly sure what all AIO does for ethanol fuel, but I figure it will not hurt. It also is supposed to have friction modifiers in it, which may help with gas mileage (not a real concern on the bike, but another plus) I think it would also be very helpful for any fuel that may sit in the carbs for any period of time. I try to shut the petcock off and let the bike run out of fuel if I won't be riding for a while, but sometimes it may not happen. I think it would help keep it from varnishing or gumming up as well as helping keep the fuel "fresh" when not ridden. I have almost year-round riding, so no long term storage needed. Any reason to not do this? The FAQ did mention that "massive over-treatment" could cause fuel dilution of the oil due to possible fuel blow-by, but I don't think 1/2 oz per 3 gallons would rate as massive over-treatment (regular dose is 1-2 oz/3 gallons). I have run 2 tanks so far at the regular dose rate, and current tank has . The bike is low mileage (just over 7,000 miles) so not really concerned about any carbon buildup, and being a carb'ed bike, no clogged fuel injectors (and the carbs were just cleaned and sync'ed).
