Injector Cleaners

Hi Guys

I am going to be doing a long trip down to the northern cape in December and was considering using an injector cleaner to take benefit of the long running time the engine would be doing.

Im not experiencing any issues and its purely as a preventative measure,

what are your thoughts on using injector cleaner and which brand is best/better ?

Edit* Its on a F30 328 with about 85k
