This is my first year where I'll try using Oil on the axles on mine and my boys cars and I'm a little paranoid I'll end up with lint on the axles. (I've read its so important to have clean axles that some people use a jewler's loupe to make sure it's clean.) Does this only matter for you national racers who are looking to shave off .0005, or is that for us small-time cub-scout and awana racers too? I've read any amount of lint will slow it down when using oil, and that makes sense. I guess im wondering how much it will slow it down. Would the presence of lint on an oiled axle slow it down to the point that graphite would be faster?
