Toyota requires synthetic 75w-90 and i wouldnt run anything less. Personally i run 90w-135. Little heaver, keeps driveline quieter, probably hurts my mileage...

Used the Mobil 1 75w90 LS myself. From the research, looks like 30k is a good interval either way.
I think its dino from the factory tho with LS additiv? If you go dino, just make sure its LS (limited slip).
I've always been a fan of Valvoline syn blend too.

Yep, like Burt.
AMSOIL Severe gear 75W90
In my opinion. I like to put the best oil in my rear end/transfer case. No pun intended...

The only version of the 4th gen 4R that need the LS additive is the Trail Edition for the rear locker. Otherwise the LS additive is not necessary. All 4th gen 4R except for the (TE) have open differentials.

Thanks for the correction. Still learning myself as I go.

The LS additive is not necessary (can be used, but not required) for any 4th generation including the Trail Edition. The TE has an electronic diff locker, not a limited slip (LS) differential with clutch packs.

Just changed the front and rear diffs and transfer case fluids to Redline's 75W-90 Synthetic and I can honestly say that I've never handled a more slippery gear oil in my life!
The 2007 4Runner Sport 4 x 4 feels as if it glides across the road's surface with barely any hint of friction.
I got turned on to Redline while changing the fluids in my Harley Road King Classic where the tranny and primary were incredibly smooth shifting with a lot less noise.
I plan on leaving the Redline in the 4Runner's diffs and transfer case a minimum of 30K miles... maybe a whole lot longer.

Getting ready to do the same thing- I guess Amsoil 75W90 it will be unless someone has a better option. I do like the Motul and Motorex oils but they are hard to find.
