Source for Kendall NS-MP 80W90? Seems discontinued...

[fanaudical]

Well, I guess this is yet another oil thread...

I have some remnants of a case of the Kendal NS-MP and have been casually looking for a replacement for when that's gone.

I'm a LiquiMoly fan; their oil-finder database points toward this stuff (mineral-oil GL5):

I haven't tried it yet. I have compared this to the Shell Spirax MB90 and all the tech specs are very, very close. Here are the tech data sheets for both:

Swepco 201 datasheet for reference:

I have tried finding a TDS for the Super Tech 80w90 and haven't located one.

In 1973, it was a 915. 901's (with the cool dogleg) were last installed in 911's in 1971.
