[MSCW list] RX8 Engine Oil: Use of Green Earth Tech Engine Oils

[JBRERX7 at aol.com]

For RX8 club members,
 
I saw and ad for a line of engine oil products from the referenced  company 
(_www.getg.com_ (http://www.getg.com) ) and there is a  conventional oil 
along with the usual synthetic and a bio-engine oil.
 
Do any of you have any idea if this type of oil can be used in my  RX8?
 
I've also logged onto the RX8 Club and await their comments-thanks.
 
Regards,
John Becker
