Does anyone see a issue wih using Amsoil Severe Gear 75w-90 (SVG) for both the front and rear diifs? And using Amsoil Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid (ATF) for the transfer case?
Depends upon the year. After 2015 they shortened the interval. Also if you bought used and it is CPO'd also may affect the duration. My 2015 is 5 year/100,000 mile from the factory. Since I bought my PE vehicle (I worked for FCA) and it is CPO'd it now has a 7 year/100,000 mile factory Powertrain Warranty.
