suzuki 4 stroke oil and gas additives

[captg]

Hello....2001 Suzuki 4-stroke 115hp
Is it advantageous to add "Slick-50" (or something similar)to my next oil change??

What additive added to the fuel would be advantageous to help keep clean?:

I would add nothing to an ECM controlled EFI engine.

Modern fuels and oils have all helpful additives already.

Todays engine oils are so good that no additives are needed or recommended. SeaFoam or Stabil can be added to the fuel. I and many others on this forum are partial to SeaFoam.
