Fluid change weekend.. Need suggestions

Ok so this weekend I'm changing oil, both differentials, tranny fluid , and maybe transfer case .. I need some suggestions .. Oil I am gonna get Mobile 1 turbo diesel truck 5w40 .. But not sure if filter makes a difference? Not sure on what brand you guys recommend for differential fluid .. I got the additive from dealer cause I have lockers but they told me to put some in front also .. Is this true ? And I have a 6 speed and have no idea on the fluids for that or transfer case ? Any recommendations or reviews would help greatly

For my differentials I just use the store brand typically. The differentials aren't typically picky about the oil they're getting and even over a year the oil is still looking good. Grab locker additive from the store when you buy the gear oil. I use typically 80w-90. For the transfer case, use ATF+4 and call it a day.

Common TJ Maintenance Info

Here's a great writeup about typical fluids in a TJ. For the oil filter I use FRAM. Jerry got to actually tour the factory and was even impressed by they're quality. Avoid Purolator, I've destroyed those filters just trying to get them off. Others recommend the MOPAR filter, and you'll get even more suggestions.

It's got a Willy's body, a Chevy engine, Ford axles, GM transmission, and Dodge steering components... it must be a Wrangler.

I've been using the purolater pure one oil filters for a few years both in my TJ and my motorcycle with no problems.

Never use Fram filters, always use Purolator. They are simply the best. Only use the OEM recommended oil weight. I have been a mechanic and I think you can trust this advice.

I like Shell or Shell owned Quaker State, Pennzoil products. Shell makes more lubricating oil than anyone else in the world... is there a reason they are so successful? I know I can buy cheaper.

Oil filters.... Napa Gold made by Wix
