The last time i checked on prices (early last year at royal purple was actually slightly cheaper than comparable mobil 1 from the nearest autozone.

The reason i checked was because a consultant we work with. He is a rotordynamics specialist (has been consultant on everything from little turbos to pumps used on space hardware to massive industrial gas turbines)
who is also a tribologist (sp?) (study of lubrication and bearings). He was talking to me about it after work one day. he showed me the results of some testing he had done on royal purple oil and also other synthetic and also blended oils. In every instance the royal purple was better than the others and in some tests it was greatly better. He used to use Mobil 1 in all his cars and now uses royal purple. i've just been too lazy to track some down locally to use it in my car.
