According to motortrend.com the new formulation of Shell Rotella(R) T Synthetic 5W-40 will be available in bulk, drums, gallon, and quarts beginning May 19,
2008. I can't find anything on the shell site though. I know a number of us use the old formulation I hope this new one is just as good. This is
suposed to be JASO wet cluch OK'd. All the hype sounds good. I'm hopping to find some next week and try it out as I'm ready for a oil change.

Shell Rotella(R) T Synthetic 5W-40 can help improve fuel efficiency up to one percent compared to conventional 15W-40 motor oil through decreased friction and by reducing the energy used to pump the motor oil through the engine.
