With all the trouble the 900xp motors have with oil usage/ leakage, would an oil additive help like a Lucas oil stabilizer, or Shaffer moly? Just wondering, I bought a xp with a dusted motor and replaced it with a low mileage motor and just don’t want another issue. I know keeping the air clean will keep a motor happy, but I want to do all I can to keep the oil happy too. I run rotella oil had good reviews and I have used it in my vehicles with good luck.
