fluid change

I am changing all my fluids this weekend, and wanted some input on a few things:

1. Opinions on diff oil for ARB's
2. Oil for a 94 D90 with 113000 miles on it
3. Part number for oil filter (wix)
4. Transfer case oil

What do you guys use? I've been using high mileage oil, and 80w90 in my diffs, but just installed ARB's and want to see what you are using in your trucks.

I've got 122,000 miles on my rig, and have been using Mobil 1 10w40 high mileage synthetic oil but plan on switching over to Rotella next change. I use the Redline MTL for tbox as well.

1) Use what ever is cheap and change it often. The slightest amount of water contamination will ruin your ARB o-rings. I change my diff fluid with every oil change at ~3,000 miles.
2) After tearing into a few Rover engines, I now swear by Rotella-T oil.
3) WIX and Mann are the same filter with two different names printed on them. The Mann is a little cheaper in price.
WIX: 51515
Mann: ERR3340M
4) I like the Castrol EPX 90. It meets the MIL spec's (MIL-L-2105 or MIL-L-2108 B, C, and D) and seems to have worked well over the years.

Continuing 80w90 will be fine for the ARBs, they're not picky. I'm not convinced the synthetics are worth it. Rover V8's do well on Rotella, x2 on that recommendation. The LT230 also wants 80w90. Redline MTL is a bit light unless you live in a cold place year round.

I know you didn't specifically ask for transmission fluid, but I used Amsoil Syncromesh Manual Transmission Fluid (also says 5W-30 on the bottle) in my R380 replacing whatever was in there before. I've noticed a difference (for the good) in shifting, especially in cold temps and between 1st and 2nd

Redline MTL for an R380, but the LT230 needs 90w, or 85w140, depending on environment.
I started using Drydene ESGL 85w140 years ago and continued after they got bought out by Castrol. I've used it from Georgia to Vermont year round.
WIX 51515 is the long filter. Baldwin/Hastings B2 is another quality long filter.
I pay about $5 for the 51515 here at a local heavy truck supply place.

Unless things have changed recently, MANN filters are made by the MANN-HUMMEL group. I don't see any connection between the two.

NAPA1452 filter. The specs on that Mobil 10w40 high mileage are pretty awesome, Ive been using the Amsoil 10w40 with zinc, amsoil specs are awesome but its a pita ass to get sometimes. I know at my local vatozone the Mobil is priced closer to Amsoil lately.

Royal Purple in everything. Synchromax in the tranny and 75w90 max-gear in the diffs and t-box. There is a noticeable difference.

FYI: The wix filter (I get it from Checker/O'Reilly's) is about $5 whereas the Napa branded wix here costs $12 for what appears to be the same filter.

Thanks to Tom I've been saving $7 an oil change.

Nothing beats Redline MTL in an R380, Ive tried them ALL. I always get my filters from NAPA, if they were good enough for the drill they are good for the rover.

Is the 51515 filter too long for a 94 3.9?
