What's the 2006 toyota matrix rear differential fluid type?

The 2006 Toyota Matrix rear differential fluid type iS80w gear oil. Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.If the gear oil runs low, or becomes excessively d***y, it can cause the gears to whine or howl as they turn. The whining or howling is caused by a lack of lubrication and may increase in volume as vehicle speed increases.
