Stop Oil Burning Old Lawnmower, 50W Oil and STP

Stop Oil Burning Old Lawnmower, 50W Oil and STP.
This looks like a pretty good fix to get more life out of an old lawnmower that burns oil and has low compression. I dumped out all the old oil in the lawnmower with the worn out pistons and rings and filled it with fresh straight 50 weight tractor oil. i also added a little bit of STP to the straight 50 weight oil. There is an obvious difference in engine compression and also the sound of the lawnmower engine is smoother and deeper. Additionally, there is much less visible smoke coming out of the exhaust so the thicker straight 50 weight oil had done a lot to extend the life of this old lawnmower. Lawnmowers usually require a straight 30 weight oil or if you use a multi-weight oil in a lawnmower use either 20W-40 oil for diesels or something like 20W-50 Castrol conventional oil. Usually you won't want to use a synthetic oil in a lawnmower.
