injector cleaners

[Davey]

i have a 2003 155hp Suzuki four stroke. would like to know how often i should use fuel injector cleaner or if i should use it at all. Engine has about 100 hours on it and has never had a cleaner added to fuel.
thanks in advance for any suggestions

I use Suzuki brand, one bottle every oil change. Brown's Point Marina is convenient for Zuke stuff.
