winterization fuel question

[holinwtr]

I've heard it said on this forum that some guys put a little bottle of 2-cycle oil in with a full tank of fuel. Just wondering if this is true and what it's does for your fuel system?

Haven't heard of putting it into the gas tank but for EFI applications, you'd put it into a portable fuel tank and run the engine off that portable tank. This is how you typically fog an EFI. Some will spin on a new fuel filter/water separator and add the oil in there, then run the engine.

this is what the manual recommends.
