If you use some other brand of 75w140 gear oil, you can get the friction modifier from Ford.

Looking for a Henway.

If you have a LS, use the Ford stuff no matter what the lube you use. The clutch packs are very picky about LS additive and many have had to go back and add the Ford stuff after the fact and it is much harder to do.
I ordered all my stuff from Amazon. I used Lucas 75w-140 Synthetic and the Ford XL3 stuff.
About $50 shipped (3 qts fluid and 1 bottle FM) using the links above.

I use the friction modifier at O'rielys, - it's the exact same stuff as Ford. In fact I haven't seen a different type yet. Think it's made by trans tune or something ? Can't recall, but they usually carry it there.
