Mobil 40 weight in Oklahoma?

[Narrowrd]

I'm in OK and am having fun trying to round up straight 40 weight for my 8v92. Factory calls for Mobil Delvac 40 which I found no problem in Phoenix, but here in the land of oil wells it's proven elusive. Any tips from locals? Thanks!

There are some narrow country roads here! ;)

Try locating an EXXon-Mobil jobber. You might try finding Detroit Deisel service center or possibly a farm tractor dealership. Chevron should have a Delo 100 40wt also.

I've talked to a few tractor shops... They seem fiercely loyal to John Deere, and offended that I would imply, intentionally or not, that they carry anything but green. I'll look up the Exxon-Mobil. Good tip!
