well according to your post you must buy all your oil from the dealership............
 

since the dealership is the only one to supply this rare type of oil, oh since you sound like an engineer yourself, what railroad do you work for?

Must be good stuff. Ferrari Enzo requires 10W-60, 12 quarts @ $60 ea., or no warranty on $200K motor

My Mom's F355 F1 uses the 5W-40 at about $15 a quart

Autozone stocks it.

'01.5. Hard to argue with black and white even for the blind spinmasters. LOL.

If you don't see 0W-40 written there, you are only deceiving yourself.

Walmart has it now too.

If you like 5W40, the guys on the oil forum rave about Mobil Delvac1
