Do i need to change my lawn mower's oil?
what will happen if i don't and the color of the oil is gray it has been used do i need to change? Briggs&Stratton engine compare to car oil which gets dark and black
Grey oil means you got water in there and the oil needs to be changed immediately. Otherwise I change my oil once per season, but I have a small lawn that only takes about 20 minutes to mow.
