I run a mix of 32 to 1 and see smoke from the exhaust I run pipes with mufflers and they tend to collect oil in the muffler that will smoke until the whole exhaust gets hot enough to burn out or blow out the excess oil residue
too much oil will carbon up the engine and that is not good.
What you did shouldn't hurt the engine just don't make a habit of adding extra oil.
With the colder weather the engines will tend to smoke more no big deal you will just leave a smoke trail if there is a way to color that smoke I'd like to know red smoke or green would kind of be cool anyone know how to color the smoke from the exhaust?
