Does this look like a problem to you guys? This is an old quart I found in friends shop and I transfered it to a larger jug and did not pour into the engine. I did not see any Sludge transfer during the pour. I cracked the seal when spinning cap off, but these bottles do not have a foil seal on them.

Not sludge, additives that dropped out. Put some oil back in, shake it, dump it in.
I might shake it up and use it, assuming it meets the required spec. That bottle looks really old and some modern vehicles have a very particular oil specification.
What would make an API SM oil so inappropriate here that you'd only use it in a "worn out rust bucket"? Technical reasoning please.
+1 fall-out
I ran 68’ era Pennzoil from cardboard cans in a 98’ Bonneville with a ULTRA filter. No issues.
That's good to hear. I'm not sure how those old cardboard cans look?I ran 68’ era Pennzoil from cardboard cans in a 98’ Bonneville with a ULTRA filter. No issues.
That's got the SuperSyn! Excellent stuff IMHO
I've gotten myself into the habit of shaking the bottle before use. It seemed to be worse with Pennzoil but I believe it was mostly due to the yellow colored jugs so that you could easily see the dark spots of the additive which fell out of suspension. SM ended around 2010 and would work in everything that I have.

Even my 2011 Nissan Frontier specs SM. Send it over, I'll pour it in with confidence.

Assuming this was new, but older oil, put the oil back in the bottle, warm it up inside, shake and then use.
Yellow can with Pennzoil logo. Said “with Z-7!” Below Pennzoil logo. Dad still has 2 cases unopened from 1969 I think
Yes, that’s it
