We rotary guys live for these oil discussions as choosing the right oil and following the right procedures determines when you are going to face a rebuild. :-)

I run Mobil 1, 10W40 for my turbo D, and for it's tranny


here's the deal:

if you live in the northern states, then 5W30

if you live in the southern states, then 10W40

if you live in the middle states, then move either to the north or to the south or run 10W30
