[75Carrera]

Yea Kurt,
It does appear the T6 provides a different viscosity that may quiet minor engine noise as well as increase the life of these motors. My learning curve has been a steep uphill climb to better understanding this car. So many systems, bells and whistles to sort out. I love the car but after nearly 30 years with my faithful and comparatively simple air cooled 75, this amazing turbo is an entirely new world. Reenlist posts on this subject strongly support the use of Rotella. I have never had a synthetic oil in any of my cars. I know the factory sticks by the M-1 and many owners do as well. These turbo motors spool up so fast and are are so precision oriented compared to our bare boned early cars I am planning to go with the the added protection of the diesel oil. Still looking for reassurance through the various blogs.
Thanks for your input. Tuesday I'll take it over to Darin DeYoung's shop and make the change along with the usual oil and air filters. This car has more than enough "performance" for me. The goal is to enjoy as long an engine life as possible. Better protection via the Rotella seems a no brainer. I have used it in "Precious" for several years. So far, no reason not to use it in the new ride.
Thx again...
