Engines like oil. A lot.
Somehow, in the busyness of life, I forgot that little tidbit, until the riding mower started sounding rough. It turns out, adding oil after the damage is done, doesn’t undo it. A piston through the engine casing is an expensive reminder to regularly check the oil in ALL vehicles that require it for smooth operation. Oops.
The cost of a new engine? $1600 installed. Yes, I could get a whole new mower for around $3000 but the body on this mower is sound and with a new engine – especially with oil added occasionally – should last a long, long time. So we decided not to treat the mower as disposable, and to repair the damage done.
