Johnny.....I operate on a 5 month use and 7 month storage schedule.
Manual says to treat gas and run for a bit and then fog
cylinders.....which is exactly what the dealer does at the end of the
season. And yes, this is a 4 stroke motor and no one confuses 2
stroke oil with 4 stroke.
In the spring I burn off the previous years treated gas and then
change my water filter. Motor starts up right away and might smoke
for a couple of minutes...but works well after warming up.


You have to consider how old the gas is that you are treating. The
clock starts ticking the minute you fill your tank. Fuel stabilizers
only stabilize, they can't help old gas.


How old is the gas by the time it's delivered to your local gas station?

Someone told me once that I should put an additive to the fuel in the
first diesel powered boat that I had (unless I was using it daily and
going through a lot of fuel quickly). Diesel fuel is a breeding ground
for "bugs" that can clog fuel filters if they get too bad. But I
mentioned it to the marina owner who sold diesel. He said the
recommended additive to prevent bug growth is put in the fuel by the
distributor, so don't waste my money on it.

Maybe gasoline is also stabilized at some point after refining but
before delivery to retailers.





The age of the fuel would have a lot to do with your distance from the
refinery. My point was that adding stabilizer early would yield the
best results. Adding it to stale gas is a waste of money.
