A presentation prepared for Automotive and Industrial customer on the awareness of application of after-market oil additives to finished lubricants. NOTE: This contains parts of the standard Mobil presentation decks.

1. Lubricant Additive System and
Aftermarket Additives
kasjaca.Jan.2011

2. Why additives?
 Base oil alone is unable to meet the demands of a modern
engine.
 Additives add ‘new’ qualities necessary for specific
applications.
 Enhances existing qualities of the oil.

3. What are examples of additives?
• Friction Modifiers
• VI Improvers (VII)
• Pour Point Depressants (PPD)
• Seal-swell Controllers
• Oil Protectors
• Anti-oxidants
• Metal De-activators
• Anti-foam Agents
• Surface Protectors
• Anti-wear
• Corrosion Inhibitors
• Detergents
• Dispersants
• Friction Modifiers

4. Three Main Types of Additives
• Modifiers
Modify the characteristics of base oil to render it more
suitable for use in engines
• Oil Protectors
Protect the oil to prolong it’s working life
• Surface Protectors
Protect metallic surfaces to reduce corrosion, friction,
and wear

5. If Oil Additives are so Good Why Don’t the Oil Companies
Make Them?
• Oil Companies make additives, but they don’t sell it as it is.
• Many of the additives used in the aftermarket industry are
actually purchased from the oil companies.
• The public is unaware of this though as most all oil companies
run their additive divisions as separate companies under their
corporate umbrella. They include ExxonMobil.
• ExxonMobil has more than a hundred years of experience in
lubricant and lubrication technology. They produce finished
lubricants with carefully formulated additive system.

9. Why Don’t OEMs Recommend Oil Additives?
• OEMs have spent millions of dollars developing and
protecting their engineering to insure that the engine, on
average, lasts as long as they engineered it to last.
• OEMs trust their equipments’ performance from companies’
products whom they believe will not only improve its
performance but also protect it.

10. Dr. Michael L. McMillan
Research Engineering, General Motors
"These supplemental aftermarket additives may upset the
careful balance of additives already in engine oils, and actually
cause engine harm, increase wear or adversely affect emissions
or fuel economy. This is why General Motors specifically warns
against the use of supplemental additives in owners manual
recommendations to GM customers."
