I have a 9N that smokes bad and uses about 2 Quarts of oil when plowing for half a day.
I was watching a video that showed an oil additive that restored the engine, giving less blow by an more compression in sparkplug. I realize this is the cheap way to help the problem. I am concerned that the thick viscosity of the engine restorer may plug up something on these older engines. Any one have experience using this product or other similar products?
