I don’t know if I’m losing it through a bad gasket or just burning it, but my mower (scag swz 52” with probably 700 hours on it) is using a fair amount of oil. I actually checked it the other day and it didn’t register on my dip stick.. not a good feeling. Anyway, it calls for just good ol SAE30. Should I run something else(maybe a 5w-30 high mileage) to slow down its consumption? Or is this just the nature of the beast?
