Mystik or Pennzoil GL-5???

[FastSUV]

I want to run a dino gear oil and can get both of these for a decent price...which is better & why?

My rear diff is limited-slip and I am assuming both of these are formulated accordingly? My front diff is open so it won't matter...

The Pennzoil is a good gear oil and does have the LS additive in it. I would not hesitate to use it. Have no experience with the Mystik

I've used Mystik Gear oil for many years in big truck rear-ends and trans. Never had a problem with it. However, I've slowly got away from the Mystik Gear oils because I don't think the quality is still there like it was when it was owned by Cato Oil. I still use the JT-6 Hi-Temp Grease but not the gear oil. I would go with the Pennzoil.
