how often is it reccomended to change out the differential fluid? is it easy to do it yourself, or will you need a lift?
Here is the "How To" on this fluid change:

The Mustang uses a clutch-type LSD (limited slip differential) that relies on slip between clutch plates to apportion power appropriately to either rear wheel. If the differential lubricant has the wrong friction coefficients, the clutch plates either slip too much or not enough. That's why specific lubricants and friction modifiers are needed in clutch-type LSDs. They are usually specific for type and brand.
The S2000 uses a Torsen LSD, a mechanical type that relies on the intermeshing of gears to apportion power. In this type of LSD, the differential fluid need only lubricate the gears correctly, and no friction modifiers are needed. It is nearly identical to the LSD used in the Mazda Miata and RX 7.

Man, this issue is still getting beaten to death after "the truth about 90w..." was posted years ago. Oh Ye of little faith!
1) It is mostly Honda's fault - they spec an oil that is generallt hard to source, and in most cases has a pour point too high to be practically used in much of the USA where temps average below 32degF in winter.
2) I did a lot of research to find LE607, and still use it in my car. LE revised its line of diff gear oils, and now it is LE1604 that is the 90w gear oil.
some relevant specs about LE1604
- it still has the lowest PP I have seen in a 90w - minus 11 degF
- it is GL-5 rated http://www.lubeng.com/search.asp?ID=ALLDOCS - that post that said use of it would void the warranty is wrong
- LE uses an aluminum magnesium additive package that has high shock rating - probably very good for those of you who drag race and do clutch dumps since the beveled edges of the ring/pinion need all the help they can get when such high inertial forces are in play. Almasol is proprietary and unlike anything else out there that I have uncovered. Some of the gear oils foam up badly at high RPM, and foam is a poor lubricant, believe me.
3) I still have it in my diff. No, I do not work for them or have any financial association directly or through any reseller on this site. I have seen this allegation posted by some Amsoilers, and resent it deeply. Attacks ad hominem are lowly and usually come from those without the brainpower or the product to play on a level playing field. Shameful!
4) I do not think an annual change is necessary - gears are hardened steel, and after they break-in, normal wear metal in suspension will do little or no harm - fresh oil has lightweight volatiles that burn off over time, reaching the 90w stability in time. It probably does not hurt to do it annually, but it is possible.
