Well, with over 40 years experience with the stuff, MMO is very
effective at feeing up moderately stuck rings, quieting down noisy and
sticky hydraulic lifters or timing chain tensioners and conditioning
leather accelerator pump cups - among other maladies experienced by
MANY engines.
In today's engines, it does appear to also solve sticking and dripping
fuel injectors a good percentage of the time. Not foolproof - but
always worth trying when the option is dissassembly of half the intake
system to remove injectors for proper cleaning. $9 to have a better
than 50/50 chance of avoiding $400 worth of repair is well worth it in
my experience and opinion.
It was the first thing to try on the old 230 cu inch Chevy six when
lifters got noisy (a common occurence) and quite often the last step
required. Rislone worked too, sometimes - but usually took a bit
longer - and was more likely to cause goey crud to turn to cinders in
a poorly maintained engine. (more solvent - less lubricant)
Engine (4 cyl aircraft) sitting for a year or more has a "limp" when
started - one cyl down on compression. Cyl leakdown shows 40/80 on 1,
70/80 on 2 and 75/80 on one.After 20 minutes of running - no change.
Put MMO in the crankcase and run for 20 minutes and 75/80 all across
the board. And that is not a one-time experience - just an example.

The stuff has a pretty good record for removing "greenies" from
carburetors left overwinter with ethanol gasoline, as well as
disolving varnish from carbs when used as a fuel additive - and when
added to the crankcase has a similar effect on sticking valve lifters
and timing chain tensioners
