1.2 The characteristics of Weichai special oil
1)Good ingredients are the guarantee of high-quality oil
Imported hydrocracking base oil and compound additives are favorable
to guarantee the good quality of lubricating oil.
2)Under normal use, oil drain interval can be extended by 3500-7000
kilometers (CH-4 can be extended by 10000 kilometers)
Outstanding high-temperature oxidation resistance and good Total

retention can extend oil drain interval.
3)Professional protection can extend the engine life
Professional lubricating oil for high-power and high-load engines, which
can extend the engine life (special oil can be extended the engine life by
30~40%), has been developed based on a great deal of engine perfor-
mance and endurance tests.
4
Better performance requirements
The engine performance can be improved in terms of abrasion
resistance, TBN retention, oxidation resistance, soot dispersion capacity,
fuel control as well as shear stability and the precipitate in turbocharger
can be reduced.
5)Saving energy
The energy-saving formula “low vi multi-p friction
modifier” is the guarantee of high-viscosity index and good film strength
and flexibility of Weichai special oil, which can ensure smooth operation,
low operation resistance and low fuel consumption of engines (fuel
consumption reduced by 3~8%).
6)Protecting environment: low ash, low sulphur and low phosphorous
The ash content is controlled within 1.0% in order to extend the life of
Diesel Particulate Filter <DPF>; the sulphur content is within 0.4% to
prevent the deactivation of oxidation catalyst

and reduce particu-
lates; the phosphorus content is within 0.12% to prevent the deactivation
of oxidation catalyst

and NOX control system; and volatility can
be controlled within13%
