An unofficial, but sensible, list for routine 911 maintenance

Suggested by Porsche guru Warren Hall, who adds: "I am not convinced that it makes any difference what brands of oil, grease, spark plugs you use! The one thing I know is bad for 911's is to treat them like a Honda ... that is, just fill them up with gas and drive until something breaks!!!

"The following schedule may not be optimal for all, but it is based on an owner/mechanic doing all of his/her own work -- not having a shop do this work, and it gives a starting point to work from."
