I've tried contacting Service Managers and the reps at Nissan Consumer affairs. I never get satisfactory answers w/ regard to my technical questions. (For example, is it OK to substitute synthetic in the manual transmission? Is so, what weights are acceptable? ) Does anyone know a source for technical information on the Z? I'd really like to speak with someone who knows something beyond the published facts....
Thanks for your help,
Mika
