I mowed my lawn for the last time this season late this afternoon and then changed my oil. It's a B&S 18 hp Intek and I used some older 10w30 PAO synthetic and an AA 3614 filter. After I added almost the full qt. of oil I started the engine and ran it for less than a minute to circulate the fresh oil and fill the filter. When I checked the level it was about 1/2" BELOW the ADD mark (about 12 oz. low). Would running it for less than a minute (with no load) cause any damage? I was rushing because it was getting dark and I confused the capacity with my snow blower.
Does the oil 'slinger' still sling when the capacity is lower?
