just got hit with a $700 lesson today. my oil level was a little low, (the add level). today i was running it and BAM! it quits. I take it to my dealer and they break it apart and the oil was sludge. my warrenty wont cover because of negligence, even though the stick read that it had oil. so now i'm out $700 for a new motor. so please check and change your oil frequently.
