Giving up and asking for some advise from anyone on here who may know about fluids.

2013 Ram 1500 4x4 65,000 miles
Canadian truck built in Michigan recently imported to US

I want to change fluids

Front differential
Rear differential
Transfer case ** Not sure if i have BW44-44


Problem i am having is finding a lot of different information on the fluids the truck needs.

I called the dealership and he recommended 75-90 non GL5 for the front and rear and didn't sound confident and he looked it up using my vin.
Called another dealership and he recommended something totally different and they weren't alias part #'s


i have only had the truck about a month.

Just wondering if anyone knows the best fluids for this truck.
Any help is very much appreciated.


Have looked up Valvoline, royal purple, AMS oil but they don't really specify GL5 rating.

If you have the "Auto 4X4" button then it's the BW44-44, if you just have 4X4 Lock & 4X4 Low then it's the BW44-45
As for the differentials, if you don't tow or haul anything heavy you can use a good 75W-90 in both front and rear. If you do tow heavy then use the 75W-140 in the rear

Red Line or Amsoil in the diffs, as noted above use 75-90 in the front and 75-140 in the rear with the added limited slip if you use Amsoil, Red Line has it built in so you should be okay without the additive.

If you have the Auto 4x4 I opt for the expensive Mopar fluid, if not, Amsoil or Red Line again.

You have the owners manual, so do that. Mopar spent a ton of money researching what to use in their equipment. Same advice as what the other guys gave; and they are correct about how to tell which transfer case you have.

Leave the RP alone, don't use lucas or mopar either, study hear.

Amsoil is good because they have bags, no need to get a pump. Redline or m1 great as well. @Hemi395 has used a couple different options in his ram without using that b44 unicron ****. Do a search on that, no reason to buy that stuff.

Mammas Don't Let Your Babies Grow Up to Be Cowboys or ever let them use royal purple gear oil I think is a famous song.

@danielrly , as the gents above have said, use your owner's manual as a guide, and check your 4x4 buttons to see if you have the BW 44-44. You can probably be safe with the alternative oils they recommend as well, but it's your decision on how "safe" you want to be. You can supplement your owner's manual with the Mopar Vehicle Lubricant & Chemical Catalog, which should include the Mopar part numbers, and occasionally the applicable years, for the Mopar versions of the fluids you need.

I did use the owners manual but it doesn't give part #s and if you look up 75w-85 you will find quite a bit from mopar some gl5 some not and most of the diff part #s are not alias #s. So I called dealership and they gave me non GL5 part #s when the manual specifies gl5.

That's why I'm confused.

The
Manual was where I started thinking it's a no Brainer.

Also looking at the diff 75w-85 or 75-90 supposedly the reason for some diff part #s is some are extreme heavy duty and some are not even though same weight rating and synthetic and GL5. I'm not an expert here, so did a bunch of research and gave up due to more confusion and made the post for guidance.


Appreciate the help fellas
