Still factory oil filter on mine too Bill. I will be changing the oil this winter and replacing that filter with another one that is not Briggs. I am using Valvoline Next Gen oil in the Briggs. Since I reset the hour meter somehow, I know how many hours are on the engine and when to change the oil. Had a guy tell me to do the 1st oil change at 50hrs and then every 100hrs after that. I may get 50 hours in this year lol
