There are many who will disagree with you, depending on the
I've used coal oil,deisel fuel, ATF, Shaler Rislone, Bardahl #1,
Casite engine flush, and a host of other commercial engine flushes
over the last almost 40 years. Only lost one engine to it, and it was
beyond help before the flush. If I had dropped the pan right away a
set of bearings and an oil pickup screen would have salvaged it, but
hindsight has 20-20 vision.(1965 225 slant six with a split oil pickup
screen due to some hamfist working on it previously)
It's not so much what you use as how you use it, and what you are
attempting to accomplish. It is a WHOLE lot easier to, for instance,
adjust the valves on a flathead Dodge or Continental, when you can
actually see the tappets.Or when you have an engine that has sat for
6-10 years and although it ran fine when parked, it smokes badly when
restarted due to stuck oil control rings due to sludging.
In the case of a heavily sludged engine you need to be gentle and take
your time. On a relatively clean engine, like the one with stuck
rings, you can afford to be more agressive.
The best way to remove engine sludge is to prevent it. Adjust oil change
intervals according to operation parameters.
Lots of highway miles for example are better than short trips that don't
warm the engine up. If the engine sits a lot change the oil every few months
or, for synthetics, check with the oil manufacturer. Always change the
filter with the oil.

Definitely no argument there, Budd, but when you are in the business,
as I was, you always ran into the guy who "knew better" and was proud
of the fact he never changed the oil, or the guy who was just
forgetful and neglected to change the oil, or the guy who used the
cheapest oil he could get.
Or you got the guy who bought the car one of those guys used to own.
In those cases, the judicious use of a flushing agent was often

There are two brands I hear about more than any of the others, The
better of the two IMHO anyway is called RESTORE, comes in a cylinder
shaped can about the size of a large can of tennis balls.
The other brand I hear about good results from a lot of people who
swear by it is called "Rislone". In addition I have used Amsoil's
engine flush prior to every oil change in my 1999 Durango SLT 5.9l. I
slowly have become a big supporter of synthetics in general, but I
don't exclusively se Amsoil's products. I have used Mobil 1 seemingly
forever and the engines I have maintained that used it in the
crankcase have usually gone well over 200k or more with no major
breakdowns or increased oil consumption. I usually complement Mobil 1
with an oil additive called Tufoil (made by Fluororamics on the east
coast) Use Amsoil's transmission fluid over Daimler Chrysler's ATF-4.
I do periodically use Amsoil's oil anaolysis services as part of a
(hopefully) thought out , effective maintenance strategy that prolongs
the useful life of my vehicles and helps to reduce the probability of
a roadside failure. Engine and automatic transmission flushing about
every 3-5 maintenance intervals is part of the big picture as well.
Good luck. Joe.
