nv4500 fluid?

it says in the book i should use castrol syntec 75/90fluid,i couldnt find it.i called the dealer they said 20.00 a quart.i found 75/90 moble brand synthetic oil for 8.00 a quart.can i use this?or do i have to pay 80.00+for mopar oil?thanks

I thought the factory lube was overpriced, and way under the so-called "lifetime fill" spec quality.

I had great luck with Amsoil in mine, MTG, made specifically for the NV4500. Retails a little under $10 a qt.


No idea about the Mobil.

No matter what you put in, it should be changed about once a year.

Pay the $80 now or a whole lot lateroke: .
