Engine/Transmission (1998.5 - 2002) Mobil Delvac 50wt synthetic manual transmission fluid in NV4500

Hi everyone,
I'm posting this because I'd like to get an idea of how many guys are running this stuff in there NV4500's, how long they've been running it, and how it's working out. I know that M1973M has done a good bit or research and is liking it so far, but I'd just like to see if there's anyone out there who's been using it for thousands of miles. I'd like to switch mine trans over two it to hopefully ease some of my rougher shifts(nothing terrible, I'd just like to see if it helps), but longevity is my biggest concern. It just scares me a little bit with this fluid being so much lighter than what the NV4500 calls for, and of course I'm concerned about those carbon fiber synchros.
Thanks!

Use the oem fluid I've tried about every kind of oil under the sun , the oem fluid seems to give me the best shift quality of everything I've tried . I've had synchros fail with both the oem fluid and other kinds of oil but I've had the worst luck trying to use the wrong oil . The little nv4500 needs all the help it can get in this application id recommend a filter setup and pto mount Trans cooler . As far as the viscosity I'll post a chart I have in a book later if I can find it
