It occurred to me recently that I've badly neglected oil changes
on our ~5-year-old lawnmower; I don't have its manual anymore,
nor a clue as to the weight of oil one would use. Considering
the low cost of the small amount of oil it would use, what
exact variety of Mobil 1 did you use?
(What sort of engine does it have - Briggs&Stratton, like
90% of the mowers in Western Europe and the US? :)
