Nice work.

I am going to make one that uses the oil particles to set the friction inside the engine. I will make it so the friction slowl increases until an oil drop sets it back to 0, just like a real engine. Two stroke engines rely on the oil/fuel mix and if it is rotating without fuel (Like if you try staqrting it with an empty gas tank and no oil) you could severely damage the engine.

Also smoke from a real two stroke engine is blue because of the oil. I couldnt find a way for the scripts to detect whether there is oil or fuel being burned, so I will try to work around that later. I might add some code in the oil itself to set friction to 0 on the things it touches.
