Answer
the only one i know of, is Lucas oil additive stabilizer, it makes the oil "stick" better to moving parts, and will (according to the company) quiet noisy gear boxes and transmissions, and improve engine internals. i would STRONGLY advise to follow all of your tractor's manufacture's remendation, and if the recommend not adding such products as they may cause more harm then good. the typical mix ratio is 1 quart Lucas replacing 1 quart oil per 5 quarts for engine oil (meaning if your engine takes 5 quarts to fill, add 4 quarts oil, 1 quart lucas.) for transmissions and/or gearboxes, use between 50-50 and 25-75 Lucas to oil
