Thumbs up here. I was just contemplating the same thing tonite.
Why not use a Synthetic like Mobil 1 10w30 High Mileage and let it clean out slowly without using solvents?
Another thumbs up here! Great time of the year for using MMO with winter knocking at the door! It will help cold starts too, a win, win IMO.
I wouldn't use more than 1 cup of that MMO because it really thins the oil down a lot.
MMO won't flush anything out all at once, it will gradually clean over the OCI. I'd run it about 3000 miles and then change back to your favorite oil and interval. If you're afraid, which you shouldn't be just add a pint for the last 1000 miles of the OCI. It isn't going to do as much cleaning but done over a few OCI's it should help. Keep in mind heavy varnish can be tough to remove so the 3000 mile interval I mentioned is your best shot at it. As you can see opinions vary, search the oil addiitive section for more.
KV40 and KV 100 values were posted I believe, and with a lucky search might be found. I do know MMO is a 5 grade oil, and 100% safe to use as "directed". Which I've done along with millions of others over decades with good results, and w/o issue. Also check the UOA section, wear numbers are usually very good, only TBN takes a hit. If you're cleaning an engine you don't want to do extended drains anyway.
Blackstone tested the KV100 of Marvel at 2.64. It will thin the oil for better flow and clean as well, but it doesn't seem to have as much effect on the base oils actual KV as you would expect.
Marvel says you can run up to 15% Marvel and expect your base oil to stay in grade, for mixes exceeding that they suggest jumping up one grade. My first hand experience with Marvel in the crank seems to have been consistent with that statement. I have also seen a couple UOA's with Marvel added, and the oil was still in grade, when the calculator would have said it shouldn't have been. I speculate that since Marvel is a totally different base oil than PCMO/HDEO it may not have as much impact on the grade of the base oil as the calculator would indicate. Never the less I consider 10-15% Marvel about ideal, beyond that requires some re-evaluation of your base oil.
I know the stuff works. I put a pint in my son's Chrysler the other day (4 1/2 qt sump) and he commented about the improved cold starts and he didn't remember I had put Marvel in until I told him again. I also experimented with a 15w40 in my Jeep and that was a mistake, a partial drain and a quart of Marvel cleared that up too. As far as cleaning, is is definitely a slow gradual cleaner, you'd not need to be concerned about the negatives of a "shock" type cleaner. I have tried to clean my Jeep with HDEO's alone and the oil stays golden, every time I add MMO regardless of where I am in the OCI the oil starts to darken considerably in about 400-500 miles.
You can put a pint of MMO in about any sump and "forgettaboutit" IMO. A quart with a thick HDEO like T5 should be about perfect.
I don't know why people insist on [censored] up a perfectly good oil like T5 by diluting it with MMO.

There's 3 reasons right there. But I'm not going to get into a MMO debate, I'm done.
And I agree the T5 is awesome stuff all by itself, I'm as much of a Rotella nut as I am MMO.

A) Buy the company
or
B) Reverse engineer it and incorporate its obviously superior chemical make-up into their own products. It can't cost much to make given the price it sells for.

^^I never heard of MMO, rebuilding an engine in a single tank of gas or curing cancer. I have however seen how well it can clean up an engine, and heard it silence lifters, many others had similar experiences. For me its worth the cash if I need to clean up an engine or silence a lifter.
I do agree with some of your comments regarding Amsoil, if XOM felt the company was a major player or super cutting edge they'd cut a check. But then again maybe they feel supplying them with raw materials is enough of a slice of the pie.
Also as time goes by I am seriously considering trying Mobil 1 again. Castrol IMO dropped the ball with the change over to SN formulations, but that's another topic.
Edit to add: MMO does float on water! LOL
