"Oil additives, you know the ones that almost everyone has tried and most
have not seen much difference, Yea those. Let?s talk about what is really
in them and what they can do to your engine.
There are hundreds of oil additives on the market. Some say that they will
reduce your mileage, or reduce your wear, or reduce your oil consumption,
and some even say that you can run your engine without any oil after
treating your engine with their miracle cure additive.
The truth is that there are 4 types of oil additives.
Solvent is one and it only cleans out deposits left by using a poor oil.
If you use a good oil you should not need to use a solvent in your engine.
Think about it, there is many places in your engine that don?t drain all
the oil out of. You know the small little valleys that hold the oil and
doesn?t drain oil. That still has the solvent it them and will contaminate
your new fresh oil. Solvent will clean out your engine but at what cost?
Solvent is made to break down oils and I for one would never use a solvent
in my engine because it would start to break down my new fresh oil and
reduce the oils ability to properly lubricate my engine.
PTFE is another one. This additive has plugged up filters has an ability
to build up on itself and affect tolerances in your engine. It only has a
500 deg F. temperature range and only holds up to 5,000 psi. Moly has a
650 deg F. temperature range and holds up to 400,000 psi. Some oils have
moly in them and if you were to put the PTFE in your engine with the moly,
you would be diluting the quality of an average oil
Chlorinated paraffin?s is the most popular additive. They show how their
oil will perform in a pressure test that has a torque wrench that puts
pressure on a bearing and a round but rough surface that is turning in the
test oil. They show how by adding their oil the wear is greatly reduced.
This can be done with household bleach but you would not want to put any
of that in your engine because it?s corrosive. The Chlorinated paraffin?s
are also corrosive to the light metals in your engine. The lead in your
engine bearings is subject to corrosion or acids that can build up. When
the chlorinated paraffin?s come in contact with moisture okind they turn into hydrochloric acid and can become acidic to the lead in
your bearings. So the reduction in wear shown by the torque wrench test is
only one realm of wear that goes on inside your engine. Acidic or
corrosion wear is another type and that is why I would never use an
additive containing any type of chlorinated product.
The last type of additive is just a SAE 20 or 30 wt that has the same
additives your engine oil comes with in the first place. In some cases
there seems to be no thought to what might happen if there are to many
additives and the oils additive balance is thrown off by throwing a bunch
of everything in your oil. This is the additive type that is least harmful
but I would recommend against using it also."
