Correct Differential Lub

I have a 2011 4WD Tacoma. It is a base model. I don't believe it has a LSD. This is what the owner's manual says regarding the gear oil needed for the differential:



Is this the correct Redline lube to use in the front/rear diffs?

I am a little confused about the LT designator. Does that mean something like GL-5? The Redline seems to indicate that it is for LSDs.

 

If you do not have a LSD then there is no reason to use that oil. If you do have a LSD then dont buy that there is no need to add additional friction modifiers. Most have found that they need them anyway. Synthetics and LSD's dont usually get along very well. Your rearend should have a sticker on it that says if it is LSD or not.

 

If I don't have the LSD, don't use it? If I do have the LSD, don't buy it? Not sure I am following....

 

Yours is a 2011, it does not have a LSD. So any 75/90 gear oil will work. The 75/85 is from toyota for a 1% increase in fuel milage. That redline oil has modifiers in it for use with LSD so if you dont have that which you dont there is no reason to use it. If you did have LSD and used it the rearend would probaly start chattering and you would be draining it and adding new oil plus friction modifier. What im saying is most high dollar gear lubes that claim to have friction modifiers in them usually dont work and require more modifier. Synthetics are too slick for the clutches in LSD rearends.

 

Ah. Very clear now. Thanks much. Mobil1 Synthetic 75w90 is readily available in my area. Sound like a good choice to you?

 

Its what i use in mine. The Toyota 75/85 stuff is fairly new and i read they have actually recalled some of the older tacos to switch them to it also for a 1% MPG gain. Not only that the Toyota stuff is expensive as hell.
