Although this syn gear oil is very good and I've been using it for a number of years for both the manual-transmission and the differential (limited slip) with very good results. However, the newer cars with DSC (electronically controlling limited slip) will not be suitable. The new generation of cars with electronic control require different lubricating characteristics. I know this review should only be for the performance of the item, and this gear-oil certainly does not under-perform, but I thought I give a heads-up to those who might want to use it for the newer generation of cars.

It is close to a one rating!! I use as substitute for MicroSoft Money, as it is no longer supported. Microsoft Money was great for what I used it for, checking balance and upcoming bills and deposits. However, with all Microsoft products, it had many shortcoming. This is especially true with regard to backup and "losing" data. Quicken is not a replacement. It does all kinds of stuff that is not really essential, but does not do the things one would like, at least without MUCH time invested. It is similar but greatly lacks the fundamental reason for using it.
