FWIW - I'm at 191K with stock driveshafts, and have used Lucas Red n' Tacky (Lithium complex / NLGI #2 consistency) on the Slips and U-Joints (and maybe once every 30k-40k or so?), and they've made it this far

 

I believe I saw someplace (BITOG maybe?) that the Toyota Transfer Case Oil is no longer packaged in the old style can... it's now sold in a plastic bottle like practically ever other lubricant. That's why the part number has changed.

 

Interesting, I see a supersession part number 08885-81080 replacing the 08885-01806 which looks like this:

 

I went ahead and got the Red Line MT-LV since its additive package seemed very close to OEM at less than 50% of the cost. I'm already at 191k with only 3 OEM/LF transfer case fluid changes so far, so not much to lose

Regarding OEM: Are both new variants of OEM LF in the plastic bottle really 2x as much $$$ as the old metal can version? Something seems odd about that. Also, I don't think it was solely the metal can that gave the old formula the Hazardous Materials shipping restrictions, and the plastic bottle versions don't seem to have that restriction that I can tell in 1 minute of searching . Seems like more than just a change in packaging...

 

those are two places where you should not even bother buying Toyota oil. When I went to my Toyota Parts Department and getting some tranny fluid and I asked him about the rear pumpkin gear oil and he said it was $130 a quart and it takes what over a quart and a half.... I laughed! And he even laughed! I don't believe anybody ever buys that,it's crazy . Buy regular gear oil of the appropriate viscosity,i recomend a product which is superior by Red Line. They are just plain ripping you off, especially if you're doing it every 30,000 miles you're just throwing money to the wind

 

From what I understand 08885-01906 is now designated as Transfer Gear Oil 75w LL (long life) and is the replacement for 08885-01806.

i don’t have any information on perhaps and increased life of the lubricant. I am tempted to send in 30k original fluid in for analysis.

Redline 75w-80.

 

After looking at this, and my sample below at 30K, and comparing to another sample found with 55K I am going to go ahead and change the fluid for the liquid gold. the T/C was underfilled by about 200ML. My numbers compare to one with 55K.

 

I think I will do a UOA on my current fill of Red Line MT-LV once I hit 30K miles on it.
It seems like these transfer cases through a ton of iron.
