Bump for the most recent discussion in OTC Oil Additives.

Does it do any harm? Probably not.
At 4 oz. per 10 gal. and 25 mpg, you are putting the equivalent of burning 1 qt. of oil per 2000 miles in phosphorus through your cat. Will that cause long term problems? I don't know, but the less phosphorus thru the cat the better.
If your goal is cleanliness, an additive containing PEA is better all around.

So would MMO thin down an oil grade if you're adding a few ounces to an OCI?
Something sounds very strange. I can tell you that the oil turning black fast like that means a couple things. #1- the Amsoil is actually started cleaning out some of that goop/gunk just like many of today's modern oils can do. (**PLEASE** boutique oil haters lets not start a big thing about who/what/which oils clean better?**) #2- Since your car is drinking (not leaking right?) save some green and stop using the Amsoil. Having to add that amount of oil is a tough pill in just 5000 miles. I do not believe the previous owner took as good care of that engine as he said or thought he did and I seriously doubt they used Mobil 1 Synthetic oil each oci. Hard to accept someone used that quality product and you still ending up with a badly gunked engine + using 2 qts between oci. Dealer either lied to him or ??? I dont any one who used Mobil 1 syn oil and came away with a gunked , goooey engine. So, not your fault and all you can do now is try to manage it. Since you live in a high temp climate, I would bump to 10w40 Mobil 1 Super Hi mileage (blend) flavor for the next oci and then check it weekly to see if it keeps going black as fast and if it keeps using as much oil. Take a clean rag and wipe out your tail pipe/pipes if dual and see what that looks like. Nothing to lose trying that oil and you can save the extra cost of the Amsoil (which I have used for years and still use in one of our cars to this day). Just it costs so much to be going thru 2 additional qts between oci, especially if you end up needing money for engine repair work later. Good luck with it. Oh and I noticed you said you added MMO into the engine. Is that still in the engine at this time? If so you should really see some black gunk come out next drain. I would drain that out within about 250-300mi just in case it knocks a lot of goo out and restricts the filter. MMO is a really good cleaner that I have used in fuel for many years but only had one time/reason to put it in my engine oil. I had a badly gunked engine one time in the late 70s after using Quaker State 10w40. Pulled valve covers to replace leaking gasket I found when installing headers on a short block Chevy. The engine looked like it had been intentionally coated in plastic or wax. MMO cleaned a lot of that stuff out over the course of about 10,000. Dont really have a need to use it anymore.I just poured in 1 qt of MMO in a Chevy 2.0L GTDI (LTG) that has 93k miles. When I started maintaining the engine, it had 68k miles. The original/current owner said that the local Cadillac dealership had changed the oil since the car/engine was brand new in 2015. The Caddy dealer swore that semi-synthetic was all that was needed. Once the owner used up the free dealer oil changes, they had it changed at Belle Tire with Mobil 1 synthetic.
Opening the filler cap, I can see a thin layer of sludge around the fill port. The dipstick also had signs of sludge, and I had to clean off the sludge using brake cleaner. I've done 3 oil changes on it already, each time using Amsoil Signature Series 5w30. With fresh oil, the oil on the dipstick was clear amber. Just driving it a day after an oil change, the dipstick oil becomes pitch black. The engine uses up about 3-4 quarts every 7500 miles. I add about 2 quarts by 5000 miles.
BTW - E10 or E20 is often painted as an evil fuel, but for those with GTDI engines (like EcoBoost), running E30-E47 allows for running a lot more timing and boost as the alcohol allows for evaporative charge cooling which raises the effective octane well above pump gas ratings. If you are running a tuned EcoBoost or tuned GTDI engine and sticking with 93 octane, you are leaving a lot on the table. The Bosch DI systems (HPFP and injectors) are generally designed to run up to E100/14% methanol, and most of the Fords share the same fuel tanks as their flex fuel counterparts. FWIW my dad still uses the regular E10 pump gas for his 1980s Craftsman lawnmower without any problems.

I see no efficacy in adding MMO to fuel since we don't have leaded fuels.
Thanks. Have not used MMO in years for anything though I knew folks who cleaned tools and equipment with it.I see no efficacy in adding MMO to fuel since we don't have leaded fuels.
