Re: which is the best oil to the air filter

I don't think the oil matters much.

I use good ole SAE-30 same as in the motor.

The principal is:
that air containing dirt particles enters the filter, as the air flow has to make an abrupt 180 degree change in direction and the entrained dirt being heavier can't make the direction change, it ends up trapped in the oil.

Do not fill above the fill line, you don't want the element resting in the oil or it obstructs air flow to the engine.

I washed out the filter mesh in gasoline and let it dry. Some tiny amount of oil ends up on the mesh.
