## Questions & Answers

**Q: So can I use this if I have a noisy diff but a non limited slip?**
A: No, for a noisy diff I would look at a Lucas oil...after you have checked to make sure the noise isn't being caused by the bad news fairy. Take it to tech and have them check the gears. Or crack it open yourself and look for metal shavings.

**Q: does my 2005 4.6L lincoln town car use this? cant find any info**
A: IF your Town Car has a limited slip differential then this fluid is indeed the proper additive if you are going to be renewing the gear oil in your T C.

**Q: can this be used on my 1997 awd mercury mountaineer**
A: This is used for a clutch type rear end?

**Q: must I change differential oil before adding or can I add to oil already in it?**
A: You could add it to the oil that's already in there but you may need to remove some oil to make room. BTW, Diff oil should be changed at 100K.
