Engine lubricating oils which meet all international specification standards.
|
PRODUCT FEATURES:
Ø Very good lubricating ability
Ø Excellent protection against rust & corrosion
Ø Good thermal stability
Ø Ensure engine cleanliness & deposit control
Ø Highly reduced wear & deposits
Ø Blended with useful additives
Ø Compatible with engine “seal” materials
UNDERSTAND THE PRODUCT YOU BUY!
Ø Quality, Grade, Specification are the priority
and not the supplier’s brand name!
Ø Watch for the packs – NEW / Second hand and
any doubtful image.
Ø Observe while decanting the oil, any sludge, corrotive
signs and others that may signify
old blended product.
Ø The color has no relation or effect on the grade
or the specification of the oil.
Ø Commonly used tactic is to provide a big size pack
while filling less quantity/volume.
COMMON LUBRICANT TERMS:
Ø SAE - Society of Automotive Engineers
Ø API - American Petroleum Institute
Ø CD - “C” – refers to DIESEL
“D” & + + + refers to “category level”
Ø SF - “S” refers to gasoline/petrol
“F” & + + refers to “category level”
KNOCK – Noise associated with the premature
ignition of the fuel-air Mixture in a combustion chamber.
LUBRICATION – Control of friction and wear
by an introduction of a friction reducing film between moving surfaces in contact
(fluid/solid/plastic).
MULTIGRADE – A grade of oil that meets extreme
lower and Higher Temperature Viscosity Limits with identified approval specification.
DISPERANCY – Ability of an oil to disperse and suspend potential deposit-forming materials so that they can be removed from the system when the oil is drained.
EXTREME PRESSURE – (EP) Chemical compound which releases wear Under extreme conditions (rubbing, sliding, high contact pressure) …. As in the case of heavily loaded gears/differentials.
FLASH POINT – The lowest temperature at which vapors arising from a sample will ignite momentarily on application of a flame under specific conditions.
KINETIC VISCOSITY – Measure of a fluid’s resistance to flow under gravity at a specific temperature (usually 40 or 100 degrees centigrade).
ASH – Metallic deposits formed in the combustion and other engine Parts during high temperature operations.
CARBON RESIDUE – Standardized test which measures the amount of carbon left behind after paralysis under standard conditions.
CLOUD POINT – Temperature at which a noticeable cloud of crystals
OXIDATION STABILITY
: Ability of the lubricant to resist oxidation and deterioration resulting from high temp.
AND/OR exposure to air.
POUR POINT : Lowest temp. at which a liquid petroleum
product will flow when it is cooled under the conditions of the standard test method.
SAE GRADE : Grade indicating the Viscosity range of a crank case , transmission or rear axle
lubricant according to system designed by SAE
STRAIGHT MINERAL
: Oils which do not contain compounds OR " Additives "
SYNTHETIC LUBRICANT
: Lubricant made chemically by reacting materials of a specific chemical composition
to produce a compound of higher chemical properties
VISCOSITY : Measure of the resistance to flow , OR
internal friction of a fluid.
( Viscosity changes with temperature )
