Look carefully at the label. Rotella changed recently to a new spec, I 
think it's CL-4 or something like that. They have reduced the ZDDP in the 
Rotella too.

On the plus side, several oil companies have recently indicated that they 
will release motor oil products for gasoline engines that have higher 
levels of ZDDP - these will be marketied as racing oils...

If you can't wait, there's good products out there already. Most cater to 
the racing community (Like RedLine, Valvoline Racing and Brad Penn and 
others)
