Hello! I am a new S2000 owner as of two weeks ago. I am going to change out the Differential Fluid and I am curious if the fluid will need a Friction Modifier added for the Limited Slip Diff.

I have looked around and it seems that everyone is just putting in the Diff fluid without a Modifier.

I purchased Mobil One, Full-Synthetic, 75W-90, GL-5 spec

Is this correct?

 

See the oil thread

"Diff Oil: Straight SAE 90 Weight
I use Mobil 1 75w-90 personally. I know many like LE 607, but there are 2 key things to keep in mind. LE 607 does not have the "official" API GL5 certification, so if you use this, and you suffer a diff failure, don't let honda know you used this fluid as they can easily void your warranty."

Also see "Differential Oil:
IMPORTANT WARNING ABOUT HONDA SUPPLIED DIFF FLUID!
Even after years of this info being out there, some folks are still getting gooned with regards to Honda supplying the WRONG DIFF FLUID! This is important enough that I thought it worthy to put up here. Take a look at these and BE CAREFUL! .....

I use mobil 1 like u got.

 

Our diffs do not need a special friction modifer for the LSD.

For what its worth, I'm using LE1605 in the diff.

 

Thank you for the info!
