Re: The truth behind EFI's and fooging oil?
If you aren't running seafoam, the engine will eventually tell you you should have. Seafoam is safe for virtually every engine on the planet whether its two-stroke, four-stroke, carbed, or injected. Seafoam keeps the fuel system clean. If you do not stabilize the fuel (using SeaFoam or Stabil) you run the risk of gummed up injectors and other fuel system components. You are in Wisconsin so I happen to know that the engine will be layed up from November until April so fuel treatment is essential. Fogging will not harm the engine either.
