    I have an older Scag TT that has almost 1500 hrs, and the original hydros. I like to change the oil every 100 hours even though it doesn't show signs of discoloration. Just remember that hydros produce an extreem amount of heat which can easily break down oil. Just like any motor, the more often you change the oil and filter the longer it will last.

    500 hours or once a year. Which ever comes first.

    I use the 5w Mobile also, but the owners manual calls for 5w-20. I like the synthetic better since it can tolerate higher temps.
