I have seen the Techron "Clean-Up" intake valve deposit
cleaner do wonders. However, this was several years back
before companies were required by the EPA to include fuel
injection cleaners in all unleaded gasoline.
My Father believes in Marvel Mystery oil - I do not. I have
seen it claimed that it will lube the valve guides. There
should be enough oil slipping past the seals to handle this
chore. I have also heard it claimed that it will dissolve
varnish clogging up a hydraulic lifter. But, I have never
had this problem, probably because I use good oil and change
it regularly.

Well,.....
This may be unrelated to techron,but..I purchased an old BMW motorcycle on
ebay.It wasn't running all that well.Actually I did a leakdown test that
showed about a 38% difference btw cylinders.Added techron for 3 or 4 tanks
of fuel.By the end of the second tank it ran a good deal better.After the
third tank I did another leak down test.
Wow only 11 % diff.So I suspect that something got "cleaned-up".I usually
don't have much faith in additives of any kind.Maybe it cleaned a bit of
carbon off the valve seat? I've also read that over doing it is not that
good as it may wash off the oil film on the cyl. ,although I did dump a
whole small bottle in a 5 gallon tank,heh,for the first shot,ymmv,Adysthemic
