When the NV4500 was designed and built there was only Castrol syntorque lubricant that satisfied the requirements of the gearbox. Since then other synthetic oils have come onto the market that do meet the requirements of the nv4500. Some of these oil manufacturers specifically state that their oil is good for use in the NV4500 and they warranty it. I have yet to see anything current that says No oil other than Castrol syntorque is good for use in the NV4500. Sure my factory manual says that but its from 2001.
Dealer cost may be $18, but retail....$29,
that's why I'm not using Castrol syntorque.
Even the Dodge parts guy suggested there are "other" oils out there.

I have used alternative lubricants in the past, I am back to using the Castrol, it performs the best.

What lubricant should I use and were can I get it?
Castrol Syntorq LTŪ 75w85w GL-4 rated, low temperature, synthetic gear lubricant is the only factory approved lubricant for NV4500 series transmissions. Some other lubricant manufacturers such as Amsoil may have products that are compatible. However, we have yet to see any other lubricant match the specifications of Syntorq LTŪ.
Castrol Syntorq LTŪ is available in quart bottles from Dodge dealers (p/n 4874459) and GM dealers (p/n 12346190). Castrol distributors offer factory sealed 16 gallon drums, plus some repackage the oil in 5 gallon pails. We sell Syntorq LTŪ in two quart jugs.
