Re: Any Engine Oil Flush or Technique Really Work?
There are only two ways to deal with this.
1.) Stick with conventional oil and change oil and filter every 3k.
2.) Do an autorx treatment.
The 93's had bad valve stem seals. The varnish is helping to seal what is left of them, so if you don;t mind on changing them, use the autorx. If this is a job you don't want to do, then just change the oil and the engine will still outlast the frame.
