Doesn't MMO have Zn and P in it? I can see that doing some good in engine oil under certain circumstances, but if it's added to the fuel I'd imagine it could make life difficult for emissions equipment. It'd be comparable to the effect of running an oil with a heavy additive package in an engine with completely shot oil control rings. I'm sure many cars can tolerate it, but...
MMO is no joke.

I can't say that I have ever noticed any benefits of using MMO in anything EFI'd but, I love it in Carb'd engines such as old cars/trucks and small equipment.
My wifes '01 Lexus RX-300 throws a CEL every time I have used MMO(proper dosage)so, I don't use it in her car but, my '04 Altima 2.5S and daughters '06 Mazda3 are both OK!
I still don't notice any benefits or differences in smoothness/quietness or better MPG in any of the three vehicles engines. NOTHING!...Maybe even worst MPG.
My lawn/snow equipment and my '80 Firebird Formula V8-4bbl all love it! As have many of our older vehicles that I have used it in, way back when! It's as though these carb'd engines needed the extra help.
88 Ford E-150 4.9L
93 Ford Aerostar 3.0L
08 Jeep Liberty 3.7L
Reasons: Smoother idle in the E-150, less oil use in the Aerostar and a better idle. Jeep nothing different, other than the fact that I like a UCL, want to keep the injectors clean, and it sits for long periods of time w/o being used, as does the E-150.
Occasional use in oil to keep things clean, or recommend to friends to stop lifter ticks or clean things up.
Other uses, Power Washer, mower, line trimmer, chainsaw, snow blower, outboard engine, 351 Ford powered boat engine. I find carbs stay cleaner and don't need adjustments as often. Flame away. JMO I've never replaced a CC converter either.

'06 Dodge Durango (3.7 V6)
'08 Dodge Ram 1500 (5.7 Hemi)
Lawnmowers, Pressure Washer, Weed Eater.
I use it in the small engines based on the recommendation of my local lawnmower shop, it worked wonders for the power of my Zero Turn Mower.
I then started using it in the vehicles after reading some reviews, it has stopped the "hemi tick" in my truck and my wife said she got just under 2.0 mpg better on her second tank on mixing it with the gas.
I'm actually checking mine this tank to see if it helps the truck.
Even if it doesn't, I'm a believer in MMO.

Are you using the "maximum" dosing of 4 oz. to 10 gallons...? If so....try lowering the dosing to 3 oz. to 10 gallons....see if that makes a difference....these newer machines and their picky codes....hehe. I find it hard to believe the ECU would "notice" the 4 oz. in 10 gallons of fuel...unless it's a bad measurement at the pump? I've found my girl friend's 4 oz. Acetone bottle works great....predosed and ready to go right at the pump
No need to mess with the oily MMO bottle at the pump, chugging away, and checking the level at the hash marks on the bottle, etc.....just keep it pre-measured....the 4 oz. dose works great for my typical fill of 9-12 gallons.....depending on how low I drive the tank
But like they say, "your mileage may vary"
but definitely try "cutting down" the dosage, to 3 oz. instead of 4 and see if that helps any....

This engine doesn't seem to like anything extra in the gas tank at the regular/recomended strength, even fuel system cleaner(s) such as Techron or Regane. Although these FSC do clean, the CEL still comes on with'em.
I'm thinking, that I don't really need any MMO in the Lexus. All the code is telling me is; that one of the sensors is noiticing that something is different/out of it's range of measurement. The next tank of gas takes care of the CEL.
Yes, I could try MMO at 3oz/10gal gas. But I'm not sure that I want to at this point. I want there to be enough MMO mix in the gas to at least do something along the lines of cleaning/lubricating. Otherwise too little of the MMO could be just a waste of the MMO, if it's not enough to do anything!
For this particular Lexus, I don't know what amount would be considered too little(I already know what is too much)...Because I have never noticed that the MMO made the engine run better in terms of smoother/quieter of better MPG.
On the other hand(OTOH), I have often overdosed carburated engines(beyond the recomended dosage) with MMO and they seem to love it! Overdosed meaning...double the amount recomended(YES, double!)

It might just be the luck of the draw in your case. I've OD MMO more times than I can count with no problems. If you care to experiment cut the dose or just stop using it all together. You really don't any other choices.

Oh, I agree!
Most likely I will not use MMO in this 1MZFE, as the engines sensors/ECM just doesn't seem to like it from a CEL standpoint. When the CEL goes on, the engine DOES NOT ack poorly, it just triggers a code usually either of the Air/Fuel Ratio sensors from Bank 1 or Bank 2. That's all!
I don't want to contaminate the sensors in this engine(I believe this "MAY" have happened) as when I was using MMO early in the vehicles life, I did experience earlier than normal A/F ratio sensor replacement. No code clearing would completely eliminate the CEL from coming on again. Only replacing the sensor fixed the issue. This is why I stopped using the MMO in this Lexus(1MZFE).
I have tried it again since though and again, the CEL lit up on the dash...That's it, no more! And as I stated earlier, FSC do the same thing. Maybe a reflashing of the ECM would cure all of these CEL's. But, the CEL only seem to come on when a chemical is added to the gas tank apon a fillup. Yes, I am following the directions
I have used MMO at the regular dosage in my '04 Altima with no ill effects or CEL's. I DIDN'T notice any benefits in the Altima either, when used regularly for a while(oh, about 1 year).

I don't notice any thing with my Jeep either, smoother idle more pep etc. But then again I don't expect to, the vehicle is pretty much new. I do notice benefits in the 208K mile Aerostar, a better smoother idle with it.
In the Jeep I'm more interested in keeping the injectors clean, and preventing flash rusting of the cylinders since it sits a long time between use.

I'd go ahead and try the 3 oz. to 10 gallons ratio.....and give it a go. Just pay closer attention to your dosing
For MMO, "less" is definitely "more"
It's a slow cleaner anyways.....but yes, carb'd engines do love MMO....and I think that's why MMO has the ratio at 1-4 oz. per 10 gallons
Cause those carburetors can "take it", as stated, even "double" doses
But newer FI engines are just a tad pickier with all the sensors.....
3 oz...or even 2 oz.....per 10 gallons should still leave a good film around the fuel pump and injectors for use as a UCL....
