True ... So does CD2 and many others ... Slowly they clean all the
deposits off the walls and into the oil ... you will see how black oil
can get.  Of course, that dirty oil is continually being pumped through
the oil pump, filter, oil galleys, bearings, lifters, rockers and on and on.
If the filter was catching it all the oil wouldn't be dirty, would it?

Back in the days when Ford recommended non-detergent oil many owners
would flush their engines with one of these cleaners then leave the empty 
container in the trunk when they brought 'old smokey' to the junk yard.

Modern detergent oils leave the inner workings of the engine clean enough.
better to leave what little sludge collects on the walls stuck to the walls.

Seafoam is pretty much a solvent, some people have said they had luck 
with it.  I never saw much difference outside cleanup and such.

Berryman?  Not used it.

Marvel Mystery Oil...  smells nice and it's a pretty red, but other 
than that it's mostly just light oil.   ATF will probably do the same 
thing MMO does for whatever you'd use it for.


Rislone is the only additive I've used that actually seemed to do 
something.   It's not blisteringly fast but it does break up crud and 
sludge... and of course turns the oil pitch black when it does.   It 
takes its time, meaning you'd have to run the stuff for a while to 
get the most out of it but I have no problem with that, just add a 
quart of Rislone in place of one of the standard 4 quarts for the oil 
changes.   After a few oil changes get under its belt, Rislone will 
have broken up and dissolved a lot of the sludge, which you'll see 
when you change the oil which will be jet black.   The insides of the 
valve covers will also be cleaner.


Rislone works.  Slow maybe, but it actually does stuff.
