I found it while perusing Lowe's online needing to find something to get the free shipping being minimum $45. I was low on 15W-40 so I looked for some on Lowe's and wouldn't you know Lowe's sells it and for less per quart than super tech which is my typical go to. I had to try to look up a pds and it's approved for Volvo and Cummins spec and with 4.2 hths. So not only guaranteed good but a bit cheaper and because they're transparent I'll keep rewarding them and will buy more even if the price goes up to match super tech which it hasn't at least yet. I already used up two 10 quart jugs and have one left.Where do you find Mag 1? I never see this stuff at the parts stores.
I'm also thinking of getting 2 quarts of mag 1 80w-90 to try out next time I order more oil given that the product family pdf says it's suitable for limited slip service fill but not the 85w-140. I don't know of any other limited slip gear oil that's close to the $6.48 per quart like mag 1. All LS gear oil is double that or more.
