Anyone have experience running this oil? Good? Bad? Indifferent?...

Hey Ron, a posting of ST 15w40 fleet would be great! I think my local wally store sells it for about $4.50 a gal. I've never seen a posting of this oil. It has to have more moly or boron than the Rotella T I'm using (Sams @ $5.40/gal).
Here's a 15 hour run of ST 15w40 on my 3.0L marine engine:

It sheared-down bad in those 15 hours.

I'm about to send of the virgin sample of the oil for anaylysis w/ TBN to Blackstone, courtesy of ToyotaNSaturn and I. I shall post a link to the VOA post when I recieve the results.
I have found that brand of oil to perform well in a variety of different applications. That being said, I would strongly urge you to run a synthetic oil due to its superior ability to keep contaminants in suspension and its super long drain intervals. I go 15,000 miles between changes on my TDI and the analysis has always shown the oil not to have been depleted.
Why when this oil costs about a dollar a quart? With the driving I do I never even make it to 2,000 miles before I feel like doing a change.
This isn't a thread about the usefulness of synthetics, this is a thread about the usefulness of this cheap oil with lab results as evidence to back up what we will say.
Then again, if you want to buy me synthetic oil, I'll use it!

Chevron Delo 15w40 was $6.97 per gallon at WalMart this week, why not splurge?
What's wrong with figuring out how good this oil is?
Besides, Pennzoil LL is 5.77

I was under the impression that WalMart gets it ST oil from different suppliers, so this formula's results are so short-lived they are meaningless.
I'm not sure, but as long as it retains the same specs and the mix is done by warren, it should be the same.
Wal mart is crappy, but they aren't that crappy. Their SuperTech filters are good.

I ran this oil in my gas turbo as an AutoRx rinse. It became thinner than water in a very short amount of miles. I'm not saying I have a ton of scientific data to back me up (I have a sample I never sent in) - but any other 15w40 I ran in this engine never thinned like that, so my experience is like doyall's.
T. Pyrek - thanks for the VOA!

If you didn't have the oil analyzed, how do you know how badly (or even if) it thinned out? You should know as well as anyone that you can't go by the way an oil looks when you drain it out of the pan.
Edit: Also, the oil being discussed in this thread and in the UOA and VOA posted is the old SJ formula made by QuakerState. The new SuperTech oils are made by Warren.

Actually Warren still lists their agricultural/fleet oils as SJ not SL. What's the cut-off for zinc for SL? They list 1200 on their spec sheet, Blackstone lists slightly under 1100.
Calcium is still under the listed amount on the Warren site so either Warren is sloppy with the recipe or this is the older oil.

G-man - I can tell that even when cooled to 25°C the sample is really non-viscous. It pours like water - I however will send the sample in to prove my point.
