Engine Oil Recommendations for Greaves
Engines
Quality of Lubricating oil is one of the key drive
factors to decide the performance, Durability and
total cost of operation of diesel engine. Hence we
have always been recommending the best
available / suitable engine oil to be used in our
engine. Greaves Ferymann
has been continuously
upgrading the products to incorporate latest
technology such as low temperature after cooling,
two stage turbo charging, electronics, air to air
charge air cooling, high power to weight ratio etc.
for meeting customer expectations of engine
performance, durability and cost of operation.
Lubricating oil has also undergone various
improvements to meet the requirements of these
changes in diesel engine technology. With this,
SAE 15W40 grade Lubricating oil with API CH-4
classification is now available in India from most of
oil companies. This is the best engine oil currently
available in India suitable for Greaves engines.
Greaves India Limited strongly recommends the
use of SAE 15W40 Lub oil with API CH-4, CES
20071 & CES 20076 classification for all Greaves
engines to get the various advantages and
optimum performance from the engine. This oil has
a minimum TBN of 10.5 to counteract the higher
sulphur content of high speed diesel available in
India.
CAUTION
Beware of the spurious oils in the market. Bad oil
quality is detrimental to engine performance.
Hence oil should always be procured from the
original manufacturer or the authorized distributor.
Lubricating oil to be used in the engine must meet
all qualities as per manufacturer’s specifications.
Greaves India recommends audit checks of fresh
engine oil to ensure the quality of oil. Facility to
check suitability of oil for using it in the engine is
available with Greaves service network.If in doubt
about the quality of lub oil, contact lub oil
manufacturing company / Greaves service network
and get oil analysed in laboratories. Do not
intermix different brands of oil as two different
brands of oils may not be compatible with each
other. It is therefore recommended that the brand
which is used for initial fill / oil change, should only
be used for top-up. Different brand of oil may be
used after draining all the existing oil i.e., at the oil
drain interval and after flushing the lub oil system
with new brand of oil.
