Looking to get some Synthetic Shell Spirax in 75w-140.
Why? Because I am putting together a Ford 10.5 rear axle for my superduty and wanting to use a Detroit true trac. My diff is spec'ed from Ford for 75w140 synthetic.
As I think many of you know Eaton is very weird about fluids with the true track diff. I was talking to their tech line the other day and was told they approved Shell Spirax synthetic for use. It's their only approved synthetic oil for use with the true trac.
Problem is, either my google foo is weak or I can't find anywhere that sells it in the US.
Help?
