That's the first I've ever hear of the Stiction Reducer causing excessive wear in the motors. Any data to support that? I would think that if it was really that bad, it would be all over the Diesel truck forums....and people would be saying not to use it, but I seem to see the opposite.
I might run it until the next oil change, and then just go with straight synthetic with no additive. I already did my oil change + additive last night.
I can't say if stiction eliminator has chlorine or not but there are numerous TSBs out against using oil additives as many contain chlorine.
The use of aftermarket engine oil supplements that contain
chlorine can cause corrosive wear to a vehicle’s engine
and possible subsequent engine failure.
Aftermarket engine oil supplements are “treatments” advertised
to enhance an oil’s properties. Manufacturers
claim these treatments reduce friction, noise and wear;
maintain higher lubricity and break down sludge and varnish,
protecting the engine components.
Many products advertise materials like Tefl on, molybdenum or graphite;
however, most fail to mention that they contain chlorine,
which can be highly corrosive when mixed with water.
Chlorinated paraffi ns were once used as extreme pressure
(EP) additives in lubricants, but the practice has been
discontinued in most passenger vehicle lubricants due to
the corrosive side effects.
These chlorinated compounds are used due to their low cost and ability to provide EP
properties, but they readily react with water and combustion
by-products to form acidic materials that promote corrosion
of engine components and bearings.
Lubes ‘N’ Greases published an article in August 1998
outlining the effects of chlorine on vehicle engine components.
Author Maurice LePera explains the following:
Chlorinated additives are not used in modern, fully
formulated automotive engine oils. The environment
within an internal combustion engine consists of high
operating temperatures, combustion and blowby
gases, moisture, acid and oxidation precursors, wear
debris, unburnt fuel, etc.
The combination of these ingredients when combined with the catalytic effectsof metallic surfaces and trace soluble metals such as copper will cause chlorine to hydrolyze – forming hydrochloric acid and other associated reaction products.
Once generated, these acidic reaction products
can cause serious internal engine corrosion problems,
especially on ferrous and aluminum alloys.
Furthermore, chlorinated paraffi ns tend to become more
reactive as temperatures rise, making them exponentially
more dangerous in hotter environments.
“Chlorine-based additives can be fi lm-forming even at
ambient temperatures, but as the temperature rises they
become aggressive and, with the release of HCl [hydrochloric
acid], can cause signifi cant corrosion.
Corrosion on the cam lobe or tappet face can also cause
corrosive spalling, outlined in an engine failure case later
in this bulletin.
Because of the side effects of chlorine breakdown, many
military and commercial specifi cations prohibit the use of
For example, military specifi cation
MIL-PRF-17331J specifi es, “[additives], if used, shall not
contain chlorine.”3 Furthermore, “SAE J357 (Physical and
Chemical Properties of Engine Oils) lists chlorine as a
