Engine Oil Additives are chemical mixture which when mixed with engine oil increases
the inherent properties of the engine oil. These additives are mixed at the time of
formulation of engine oil. Additive percentage in engine oil varies from 5%-30%, or even
50% in some cases depending upon the end application and requirements stated by
OEM
(Original
Equipment
Manufacturer).
Asia-Pacific region has emerged as the key driving factor for this market, contributing for
about 36.9% of the global demand in terms of market share in 2014. China is the
leading consumer of engine oil additives, owing to high demand for passenger car and
commercial vehicle. Demand for gasoline and diesel engine oil additives was almost
equal in 2014 but due to emergence of natural gas engines, there may be a dropdown in
the demand for diesel engine oil additives as GHG emission is higher in diesel vehicles.
Detergents, dispersants and VI improvers have higher demand in the market and
together accounts around 65% market share. Detergent additives improve the engine oil
cleanliness whereas dispersants helps in preventing sludge formation. Viscosity Index
Improvers (VII) are polymers with high molecular weight which increases the viscosity of
the engine oil. Others include metal deactivators, emulsifiers and more.
