Engine Oil Additive
Introduction
A
multifunctional additive for use in formulating crankcase oils
suitable for gasoline and diesel engines .
GL
7521 is a highly detergent additive package possessing excellent
thermal oxidation stability characteristics. it has been developed
to fulfill the severe requirements of lubricating oil for high output
engines. Finished oils containing the recommended concentration of
GL 7521 exceed the engine test performance requirements for API
Classification.
Formulations
Recommended
for use at: In
part synthetic 20W-40 oil formulation to prepare cranckase engine oil
meeting the requirements of API service category CC.
GL
7521 at optimized treat levels (based on specific engine test
requirements) can be used in formulating single viscosity and multi
viscosity mineral oil based crankcase engine oils meeting
requirements of API service category CC, CD,SC, EDL1, EPL1,
,MIL-B,EDL2, MIL-C, EDL3.

Applications
- Appropriate
viscosity at all operating temperatures & conditions, especially at
cold starting and high ambient temperatures, ensuring better
lubrication.
- Ensures enhanced engine life by providing excellent wear protection during starting, when wear is maximum.
- Cleans carbon deposits formed in the combustion chamber.
- Controls oil thickening by virtue of its excellent dispersive action.
- Extends oil life & reduces oil consumption.
- Takes care of acid formed due to Sulphur Di-Oxide & thereby reducing wear due to acid corrosion.
- Compatible with catalytic converters.
- Prevents degradation and sludge formation of the oil at high operating temperatures & speeds, thereby extending oil life.
- Reduces the friction
USES
-
Recommended
for crankcase lubrication of four stroke petrol engines.
-
Recommended
for use in modern high performance Indian cars like Maruti, Contessa
Classic, Daewoo, Mitsubishi, Hyundai, Premier 118NE,etc.
-
Recommended
for crankcase lubrication in four stroke diesel engines under medium
operating conditions.
-
Also
suitable for stationary diesel engines operating on HSD or LDO.
GL 7521
GL 7521 is
a performance package for the formulation of single and
multigrade diesel oils with Gasoline enigne capability.
Rationalisation is possible to both higher and lower performance
levels.
