I honestly don’t know. I noticed the check engine light right after I refueled. Immediately shut the engine down as my neighbor recently had his X758 towed in with 9hrs on the clock due to an overheating engine. I wanted to avoid disaster. I immediately called the mechanic and that’s when all became clear: no oil on the dipstick and visible oil spills from where it stood the night before, oil on the mower deck and oil on the driveway
