Yet another nail in the coffin of the ATF myth.
it probably works better for dealing with carbon deposits than MMO, but when people use ATF to help build compression on dry or flooded engines which are otherwise fine, it's doing more harm than MMO would.

Every used car I get gets the MMO in the gas tank and in the crankcase for like a few hours. I change the oil and I think the MMO helps break down any old sludge that might be living in my motor. On the rotary its good premix I also add it with a squirt can when I first start a new to me/used car frees sticky stuff. MMO is great stuff!
I think its good for fuel pumps too

It's better to use oil instead of ATF in a dry or flooded engine anyway. Those people still pushing the ATF 'trick' ought to be... ahem. Anyway, MMO sounds like a great lube for fuel pumps (kinda like coolant/antifreeze is a lube for waterpumps).
A don't think ATF will work better than MMO for carbon deposits. It has no solvents in it. I'm about to step out and get some cleaning supplies so I can tear down and rebuild an engine soon. I'll try the MMO vs ATF thing on some parts with lots of carbon on them. Probably some apex seals in a bath of each liquid and see if anything develops.

It looks like more carbon fell off of the apex seals in the MMO bath. The ATF bath looks the same as it did two days ago.
ATF is so thick compared to MMO. I doubt ATF can get up into the apex seal slots very well. That's one strike against ATF. It also smells kinda bad compared to the relitavely nice smell of MMO. Another strike (sort of). It also resists burning inside automatic trannies. Yet another strike against it. It also fouls spark plugs when MMO doesn't. It also produces solid compounds when burned which clogs cadilac convertors. How many strikes so far?
MMO is great to add to oil and gas, and is thin enough to easily flow up into apex seal slots. It doesn't foul plugs hardly at all (I think). Or it atleast won't foul plugs any worse than pouring oil into the intakes, you know, to unflood an engine or to help start a slow cranking engine. Both of which work fine with no residual plug fouling.
I can't say anything bad about MMO.
I'm going to try to scrape the carbon off the apex seals with a fingernail to feel how difficult it is, now that they've soaked for 48 hours...
